Hiss in Itunes

I have a new ipod and the songs download fine with no problems but recently I started to get a hiss that I can not get rid of. I know it has nothing to do with my windows sound set up because Rhapsody real player, windows media player, and other players play just fine. I have also checked my firewall and it is not interfereing with itunes. I made sure that I tunes and quicktime also have been given permission. I have uninstalled and reinstalled itunes. I have messed with the equalizer repeatedly and I can not get rid of the open hiss that has started recently. If I turn my computers master volume down and turn town the itunes player then I get a distored itunes. If I turn itunes up to the max I get a better sound but the hiss is always there. I need a dolby feature or some kind of noise reduction patch. Can anyone help please?

Open the Quicktime Control Panel and fiddle around with the Audio tab. Make sure Safe Mode is turned off and try adjusting the "Rate" to 44.1 and 48 and see if that makes any difference. You may need to close the Control Panel and restart iTunes between each change of settings for them to actually take effect.

Background hiss reappears when sharing to iTunes

Yikes! My whole question just disappeared when trying to update my profile; trying again.
Briefly, I am digitizing old audiotapes for our library's local history collection. All these interviews have considerable background hiss, some worse than others depending on the condition of the original tape. I looked around the net - including here - and found the Visual EQ. With this, I was able to get the hiss down to what seemed to me a reasonable level. But, when I shared the file to iTunes, the hiss came back, as loud and obnoxious as ever! Why is this happening, and what can I do to prevent it? It is my hope to make a Ken Burns-style movie of this audio, using photos and short film clips. But that will never work unless I can get rid of the hiss in iTunes.
My tools. A boom box and connecting cable; the library's Macbook 2Gz Intel Core 2 duo, running Maverikcs 10.9.5; Garageband 10; iTunes 11.4.
TIA for any light you can shed on this situation!
Mary

I still haven't solved the problem, but found something that helps a bit. In the older versions of Garageband, the program automatically exported an AIFF to iTunes. This new program doesn't. If you tell it to export in this format, the hum seems to be reduced - but it still does reappear. Can anyone help me get rid of it entirely? Thanks!

Hissing/Popping/Crackling/Cracking in iTunes 6.05 w/ Quicktime 7.1

I reformatted and installed Windows 2000 Server. I used to use Windows 2000 Professional, and iTunes worked fine. Now, installing the latest iTunes 6.05 with Quicktime 7.1, I get hissing/popping/crackling/cracking at semi-random intervals (as bizarre as it may sound, with one song it seems to always occur around 10 seconds into the piece if it is the first song I play with iTunes. In another song it tends to be within the first second, but it's not as consistently within that first second as the other is at 10 seconds. After the first crackle, I usually can listen for 2-5 minutes before another crackle occurs.) . I can play the MP3's fine in Quicktime 7.1, VLC, and Windows Media Player 6.4. I'm running a Creative Soundblaster Audigy sound card. I have muted all items in Volume Control excepting Wave and Master. I have experimented toggling with the Quicktime "Sound Out" section (as suggested in http://docs.info.apple.com/article.html?artnum=93610). I have done various combinations of "safe mode" checked/not checked, 44.1/48/96 kHz, 8/16/24 bit, and Stereo/Quadraphonic. Judging from Creative documentation, it ought be 24 bit/48 kHz, but no combinations worked. I've reverted to iTunes 4 with Quicktime 6? from my iPod CD. Creative EAX and "Sound Enhancer" in iTunes are both disabled, though I have experimented with turning them on and that hasn't helped either. I have used my 5 year old Audigy drivers as well as the latest Audigy drivers. I really don't know what to do.
It looks like the following threads concern the same topic
http://discussions.apple.com/thread.jspa?threadID=588534&tstart=15
http://discussions.apple.com/thread.jspa?threadID=588245&tstart=30
Both of which come to no resolution.
Just to be thorough, iTunes is installed on my system disk, a 120 gig Seagate hard drive, and my library is located on a RAID 1 array of Western Digital 120 gig hard drives. I have 640 mb of RAM and an Athlon XP 1700+ on an Abit KR7A-RAID.
Thanks in advance for any help.

I found new symptoms to my problem. It seems the cracking only occurs when there is hard drive activity on the hard drive where my music is located. When I move a large file to and from the hard drive, the cracking is non stop. This behavior makes sense when you recall that towards the beginning of every track there is cracking as I think this is when the data is being moved from the hard drive to the RAM.
I don't think this has to do with my music being on a Raid 1 array or the Raid controller since iTunes exhibits the same cracking when playing music off other disks, including those attached to the Raid controller and those not attached.

ITunes issues, hissing, store crashes, quicktime buggy, browsers issues etc

Where do it start, iTunes 7.1.3 is a bomb! I changed my quicktime settings in preferences, audio, to safemode, rate:32khz, size:16bit, channels: Stereo, Music Syntheszisor: general midi and the hissing, garbling is somewhat better. But, if you use any other application the sound again distorts. Major issue.
Next: Itunes is unable to browse Album covers on this computer!
Itunes Store: when going to movies or othe areas, message: unable to browse Album covers on this computer and then Itunes crashes! Solutions welcome!

I give up!

Hissing and fuzzy sound in iTunes

With headphones on, I hear a hiss and fuzzy sound when playing songs in iTunes. Even with no sound and with headphones on, there is a hissing sound.
I never had this problem before.
Is there a fix?
Using iTunes 9.0.2
Thank you.

I fixed it and here what I did, thank you Wikipedia:
Utilities - Audio Midi Setup
Under "Built-in output" and "output" tab - change setting to 2ch - 24bit
Hope this helps you too

Hissing sound after I turn volume up trying Bose speakers using iTunes

Now,, I am just trying this Bose speaker system (2.1) out for a couple of days to see if I would like them over my existing speaker system , which also has a subwoofer, but while I basically play most
of my songs from any playlist from my iTunes, if I turn it up to any decent volume,, I get a hissing in the background. Also,, even if I don't have any song playing,, and turn up the volume,, I can hear the same hissing sound. Now,, is this a sound card issue? or is there a setting that I am not aware of that I must adjust? Or is it typical to get hissing. Thanks

UPDATE: I have managed to get it working, after disconnecting and re-connecting over 50 times, iTunes finally picked it up and I have now completed the factory reset and everything is now working as it should

ITunes playing music - pops, cracks, and hisses

I've been playing my iTunes library for years now, but have noticed something THIS MORNING.
I try to play any song I've had since forever and I hear audible anomalies like pops, cracks, and hisses.
I try playing the same mp3 in Windows Media Player and it sounds fine.
What's the deal? Is iTunes divorcing me?
help!!!

OK, so now we know it is a Quicktime problem not iTunes, I wonder if it has got broken in a subtle way.
It might be worth trying a removal and reinstall of Quicktime.
Download the stand alone version of Quicktime (without iTunes) from here:
http://www.apple.com/quicktime/download/win.html
Now remove Quicktime using the method here:
http://docs.info.apple.com/article.html?artnum=93698
ONLY do the Quicktime part.
Next install the stand alone Quicktime.

Hissing sound on ITunes

Hello! I have trouble with me music on Itunes since I change the autorisation ID. The music sound like there is hissing sound? Thank you for your help!

Apple does make it very difficult to get support on iTunes. So I gave up on it. I just installed Real Player 10, which can play the AAC formatted songs. Strangely enough, it works just fine (strange because from what I understand, Real is just using the Quicktime API to get at the music). But the point is, the sound works. With iTunes it did not. I see plenty of posts with similar concerns, and the iTunes support article seems to not be helping many. So perhaps a future rev of iTunes will actually fix this, and I can go back (since I prefer using iTunes). But for now, I'm going with what works.

Problems with iTunes. Music skips and hisses. Sound is terrible. I have an IPad 2 and iOS7.1.

Problems with iTunes. Music. When I put on my ear buds, I hear it more clearly. There is this skipping and hisses. If you are an old (50)audiophile like I was when I was young, it sounds sort of like a record is skipping on my turntable. When I try to play a song it skips, jumps around and the Sound is terrible. I have an IPad 2 and iOS7.1. Help!!! Thanks in advanced. Spike

Try reset all settings
Settings>General>Reset>Reset All Settings
Note: Data will not be affected but settings for Wi-Fi, FaceTime, Message, Home Sharing, Wall Paper, Sound etc will be reset

Hissing and crackling through ITunes on MacBook Pro.

Funny that most complaints about this issue are from people running ITunes through their PC's. I have the same problem through ITunes on my Mac. Play music through VLC player and it plays perfectly!!

What about Quicktime Player? I don't know how much of QT VLC uses and I'm trying to test under different configurations.

WORKAROUND - Found a Way to Force iTunes Match to UPLOAD

I wanted to let everyone know that after months of living with incorrect matches (mainly The Beatles in Mono), I've finally found a semi-easy workaround to force uploads. I haven't found this anywhere else, but if someone else has documented it, I apologize. I posted this onto one of the many threads regarding the issue quite some time ago (~ 6 months), but I wanted to make sure it was seen by as many as possible. (Sorry for the long post—skip anything you're not interested in! )
MY THEORY
The basis of this was noticing that there seemed to be discrete steps to the matching process (when adding via already-ripped FILES and not CD at least):
You add the files to iTunes
You can force a scan by right-clicking and selecting "Add to iCloud"
iTunes scans the new files
iTunes reports that it is sending the file data to Apple
iTunes waits for a "Matched" or "No Match" response from Apple
If the response is "No Match," then iTunes triggers the upload
After observing this for some time, I concluded that if (edited) files could be imported that would give a definite "No Match" result, there may be time in-between steps 4 and 6 to replace the files with the real ones (which had been triggering a false match in the past). To my delight, this worked. Here's what I did:
STEP-BY-STEP:
Deleted existing files from iTunes/iCloud, but kept the files on the computer. I then moved these to a different folder.
Took existing files and converted them with dBpoweramp. This will cost money but is well worth it if you are looking for a way to force an upload to iTunes Match. I converted them using the same AAC settings (this doesn't matter), but added the "reverse" DSP, which reverses the audio. This has been enough to foil iTunes into not matching the track, while ensuring that each file will contain unique audio data. This will be quick and painless, at least for the first time. I did it this way because it will retain all of the tags AND length of the file. iCloud will get the file length from this step, and will not change it afterward...so you probably want to use files of the same length as the real ones.
Now I have a copy of the files with audio gibberish but still having correct metadata, etc. I then put these files in my "Automatically Add to iTunes" folder.
Right-clicked on these files and selected "Add to iCloud." If you use "Sort Album" like I do, you can change it before this step and it will upload into iCloud with the correct sort information. If done afterward, it doesn't usually sort correctly on my iPhone.
After iTunes displayed the message "Sending information to Apple" (don't remember the exact message), I pasted the original (correct) files and replaced my audio gibberish files. It is important to note that the filenames must be the same, e.g. "01 Come Together.m4a" if a single-disc, or "1-01 Back in the USSR.m4a" if multidisc. iTunes will also truncate the file name at 36 characters (I believe) so this will all need to be done beforehand. I use various MP3tag actions that I'd be happy to share if anyone wants them. If you are starting with a file that has already existed in your iTunes library, this will already be done (provided iTunes is managing the library).
When Apple returns a "No Match" signal back to iTunes, it then begins to upload the files which I have just pasted.
This has worked for me 100% if doing the upload one time. In some rare cases, I may decide to EQ a file and then re-upload, or otherwise edit the file. Or perhaps I have more than one version (original/remastered, or original mix/remix) that I want to coexist in my library. In those cases, I have again utilized the dBpoweramp "VST Plug-in" DSP, where I use something like Freq Show to garble the audio. It is necessary for the garbled audio to be unique each time for this to work.
A FEW THINGS I HAVE LEARNED
If you delete a file and wish to re-upload it, you can use the same files from step 2 (provided you still have them) and iTunes will recognize them as the files previously uploaded. I am not sure how long this works, but your uploaded music remains in iCloud, though invisible, for some time — even if you selected "Delete from iCloud."
iTunes/iCloud evidently does use metadata (at least Album) to help determine if you've already uploaded a song within the same album. I ran into this when trying to test an EQ/level change I had made, and even though the audio content was completely different, iTunes would not upload or would flag as duplicate. If I altered the Album field in any way it would proceed. Other tags can be kept the same.
If you do have mono content, it is trivial to use the dBpoweramp "Channel Mapper" DSP to remove one channel during the conversion from lossless to AAC. The nice thing is, I encode with Nero AAC quality 0.65 (~250 kbps VBR) and this will reduce the file size significantly. There is no real advantage to keeping both channels, since you're doing a lossy conversion anyway. Sometimes the encoders (even very good ones) don't see the file as being mono, due to different artifacts and noise in the left and right channels. Or perhaps the mono tape was transfered with a stereo tape deck, etc. Try it yourself and see if it makes a difference. Also, iTunes will report the file as "mono" when you do "Get Info." I keep the FLAC disc image/tracks in stereo so it will exactly match the CD, but only encode one channel to lossy. If you know the source is mono for sure then there is no possible advantage to keeping both channels of a lossy conversion. (If you're not sure if the source is mono, use your favorite DAW, e.g. Audacity, to invert the phase of one channel before combining left and right. Once you do that, if all that is left is very low-level noise or other artifacts, then you know it is safe to encode as mono.)
IF YOU CARE ABOUT MASTERING
It is also worth noting that if you care about what mastering you have in your iTunes library, there is no other way I know of to guarantee you have the correct version in your iCloud library except to upload it. I found this out the hard way: I had a retail CD version of Paul McCartney's "RAM" album that was recently remastered. I put the CD in, added to my library, and iTunes Match quickly returned with "Matched" for all tracks. Some time later I was listening with headphones and noticed that some tracks had hardly any hiss at all, whereas others had a good amount of it. Since "RAM" is a rather hissy album, I investigated it against the CD and finally found that many of the tracks were being matched to other versions of the song (either from the earlier CD version or compilations with different mastering). So most of the tracks were hit with heavy noise reduction for the iCloud version. I had to follow this upload procedure to be sure that I got the right version. Purchasing the item(s) from the iTunes store would work also, but I had already paid $100 for the deluxe box set. This same problem occured with the Bob Dylan mono box. I was surprised to find that iTunes actually matched my mono versions to mono versions, and continued listening until one day the stereo version played on a certain track instead of the mono. So, even if the iTunes store has the mix/mastering that you are wanting to add to iCloud, the only sure way is to upload it (or purchase it from iTunes in the first place.) If given the choice going forward I would choose the latter, since I am not hung up on physical media and cannot tell a 256K iTunes store encode apart from a FLAC file in a double blind test (almost nobody can).
This has been bothering me for months. I'm really happy to be able to play my correct files on all my devices! For those of us who have unique versions or masterings of albums we prefer, this should be a workaround until Apple decides to give us a "force upload" option. I have tested this on Windows 7 primarily. Should work on any OS.
Hope everyone finds this useful!
Nick

I wanted to first thank you for this, as this is the only workaround literature that seems to be floating around out there. With that said, I know it is a big ask, but is there any way that you could create a video showing step by step how to do what you do? I have several tracks that are stuck in waiting mode, and if left in itunes, will never upload or match...they only cause the upload process to hang up and restart. I've tried leaving it for days...I've tried converting the files, signing in and out of itunes (and itunes match), updating itunes match, and I tried your technique...unfortunately to no avail. Perhaps I didn't do your technique correctly. I used audacity to reverse the audio.
ANY help would be GREATLY APPRECIATED!!!
Thanks

ITunes 7 sound and playback problems

I downloaded iTunes 7 today and when I went to play a track I recieved hidious distortion from every track in my library. I have checked my speaker volume, system volume, iTunes volume and played other media players to see if the same problem came up with them and it did not. I also had iTunes running moments before I downloaded 7 with no problems so its definately 7 related. I have made sure the the equalizer in 7 is turned off and checked each and every setting to see if anything is messing it up and have not found anything. I have reintalled the software twice now as well. I run a Audigy 2 ZS and assume my drivers are up to date if not a fairly recent version.
I should also mention that I run Windows XP 64-bit and have all the Windows updates up to date. One thing I noticed is that the Music Store icons next to each song are only appearing when I have the song highlighted which may indicate some bugs as I know the arrows use to be next to each item in the window in the iTunes versions prior. I bring that up obviously because perhaps 7 isn't running well on XP-64 yet.
Any ideas on where I should start to troubleshoot this? The best description for the sound is a huge distortion filter where you can kind of make out the song behind layers of static and hiss. Its definately something to do with the software or its interation with my hardware and not nessicarly any volume settings that I can find.

Me too.... Just upgraded to iTunes V7. Now I cannot play anything from within iTunes. When playing a song, it is just garbled. You can hear the song enough to tell what it is. But it is severly distorted. More of a "repeating warbling" type sound. Like a scratched record that is playing the same section over a few times before moving on. Also, when I double click a song to play, it takes 12-15 seconds before any sound at all comes out.
In my other players, like Windows media, songs play just fine. All other audio seems OK. Just now cannot play anything in iTunes V7.
I have had iTunes since at least version 4 or 5, and upgraded everytime a new version came out. Each time with no issues until now.
Using Windows XP, SP2
2 Gig RAM
2 Terabytes Data storage
AMD 4800 Dual processor
Sound Card - Creative Emu 1212
Any help would be appreciated. Thanks...

Really Bad Playback Issue w/iTunes

I really hope there's someone who can help with this issue! Sorry for the long post but
I wanted to cover as many possible questions right away.
While working on photoshop files or switching between apps or windows, opening
finder windows, basically doing anything outside of itunes seems to cause itunes
to cut out briefly or completely stop OR the audio stops but the song keeps
playing. Other times a song will stop and then only a loud HISS comes from the
speakers.
I have unplugged the 3rd party speakers and played just through the small
speaker in the G5 and the issues remain.
I've done a fairly thorough search for this issue and have found a few postings
(http://tinyurl.com/yajdg6z) (<--windows version) about it but no answers offered except for one that
suggested:
"right click on the song and go to 'Convert ID3 Tags...'then from the drop down
menu pick one, mine works with v1.1
after that the song should start working again."
I converted my entire library to 1.0 and the problem remained. _I do not_ recommend anyone
do this as itunes will duplicate your entire library!
*This is a brand new (month or so) install of 10.5.8 on a 300GB drive w/tons of*
*space in a Dual 2.0 G5 w/8GB's or RAM. itunes 9.0.3 (15)*
This issue was there w/10.4.11 using the OEM boot drive and I'm still having
this issue even having done a new installation on a NEW, bigger freakin drive.
The itunes library resides on an external 500GB firewire drive with 39 GB of
space available, so no airtunes or network to contend with.
I've also deleted my entire song list twice. Once re-importing the original
files and finding the issue remained, then deleted again and imported the backup
of the songs from my backup drive in case the 1st drive the originals reside on
was having issues. I guess it isn't!
When working w/Photoshop, the maximum amount of RAM being used by all processes
is a little over 4GB. Since I have 8GB (that's the max amount of RAM this
machine can hold) AND a completely empty 160GB internal drive for Photoshop
scratch disk space, I should be well within tolerances, but I could be wrong for
unknown reasons. I have allotted CS3 it's maximum amount of RAM which is
3072MB.
I have MenuMeters in the toolbar which gives me a constant readout of processor
and RAM usage, so I'll see it if there is a spike or maxing out of the
processor at any given time. I usually never see that unless I am applying an
effect that requires that much, but the iTunes issue comes when just using a
very small healing brush and I'm cleaning up a scan.
BUT, and this is a big "but", the problem is not isolated to just when I'm using
CS3. CS3 might be running and doing nothing, and I'll be switching windows or
to a different app or just advancing to the next song in iTunes itself and bad
things will happen.
With iTunes being the only app running the problemwas minimized. I tried
opening a lot of finder windows with coverflow andscrolling and the problem
wasn't too bad, occurring ONLY when I did a title change of
a song in iTunes. As soon as Safari was opened and I had multiple windows open,
the problem was back with no CS3 running. Basically if I run any app with itunes,
itunes has problems.
I had left itunes running with some Safari windows open to some CNN pages and wasn't
even at the keyboard and heard itunes cutting in and out.
I do all the necessary utilities (DiskUtility, Disk Warrior, iDefrag, Applejack, and CleanMyMac)
to keep everything up and running so why is this going on? I have also uninstalled Perian just
+in case+ that might help. It didn't.
This is driving me nuts!
Help!
Eric

Yep, unfortunately.
I have 2 500GB FW drives that are clones of each other.
One drive I work from and the other is the backup.
I have deleted the library from itunes and loaded the +clone drives+ copies of the music instead, in case working on images while playing music from the same drive was causing the issue.
Also I switched FW ports the drives are plugged into; switching from the PCI FW card they were plugged into, to the built-in FW port on the G5.
Worst case I will just play music through the wired network on my G4 and plug in the good speakers into the headphone/speaker jack on the G4. I've tested this out using +itunes 6+ which is what is on my G4. I'll update itunes on the G4 eventually if no other suggestions come in. I may try downgrading to itunes 8.2 on the G5 unless I hear otherwise.
You're right this shouldn't happen but seems to be specific to this particular machine as a previous G5 that died on me had no problems. I bought this one used so I can't speak to it's previous history, but it demoed just fine w/final cut and HD movies that were being edited by the previous owner.
I've had this issue since getting this G5. It occurred using the boot drive from my original G5, the boot drive that came with this G5, and the present brand new 300GB boot drive that I'm gonna stay with.
Things that have come to mind as possible culprits have been bad memory and the application switcher if that's still used in Leopard.

In Version 7.1.1. Why is there a delay playing songs in iTunes?

I am an older working musician. This is my 1st iPad (Ver.7.1.1) which I bought specifically to play MP3 drum tracks in my trio. I purchased NextSong and Go Button and am trying to use an AirTurn bluetooth foot pedal to trigger some of the songs. NextSong, a great little app, is basically a controller for iTunes which contains all of my MP3s (originally produced on Alesis SR16/18 machines and recorded). I also loaded all of my MP3 drum tracks separately into Go Button which is a theatrical music/cue controller. I have two issues with playback (in either program) even without using the AirTurn pedal:
1) When the track is played there is a ramp up in volume at the beginning. It is probably around 250 milliseconds. May not sound like big problem but it is. Most of my tracks start with four drum stick clicks (imitating a live drummer) and when you can't hear the first drum click we don't start together.
2) There is delay from the moment I hit start and when the track actually starts playing (this is even evident in iTunes itself). It isn't a consistent amount of time even on the same track played, let's say, 3 times in a row. Sometimes it's 100 milliseconds but sometimes longer even on the same track. This is critical if I'm trying to start a drum track in the middle of the song (and the reason I bought the AirTurn pedal). I had a lot of correspondence with the programmer of NextSong and it seems to him that it was a problem with this latest iPad/iTunes version.
I've been all over Settings but can't find anything that may correct the problem. Any suggestions?

I think there is a problem. I dont get the noises on each song even though that happened to me on a previous update but rather than being a sporadic click it was a very loud hiss over every single track...
The latest problem with my copy is that the songs are only playing out of one speaker and its not even the centre speakers, its the left speaker.
The last time itunes didnt work properly it took apple around a week or so to correct so im not worried at the moment but i have to use windows media player in the mean time which I dont like to use.

Bazaar high-pitched squeal/fuzz noise in iTunes when scrolling.

System info:
I'm using iTunes 6.1.3 on Windows XP Pro, and I'm wearing headphones (i don't have regular speakers).
Issue:
I noticed that if I click and hold down the scroll bars in the Library in iTunes (the scrollbars for Genre, Artist, and Album), I hear a faint high-pitched squeal or fuzz noise coming into my headphones. (If I scroll through the songs themselves, I do not get this noise. It's just the three above-mentioned scroll bars). Since it's pretty faint, I only hear it if nothing else on my computer is sending out music or noise (or only if the noise is also very quiet at the time). As far as I recall, I don't remember hearing this in conjunction with any other program.
Question:
Has anyone ever heard of such an issue? It's not really a big deal, but it does make me rather curious to know what's causing it. Try it on your own computer and let me know if you have the same issue. Could it be a sound card thing? But then why would where I click in one particular program have anything to do with it?
Example file:
If you'd like to hear what I'm talking about (Since you might be tempted to think I'm making this up), I created a wave file recording of it. (I didn't want any mp3 compression to confuse the matter, so that's why it's a wav. Not that I know much about that sort of thing... but just in case.) I uploaded it to here: http://aranel.alasse.googlepages.com/itunessqueal.wav (Sorry it's so big... 5.3 MB... Obviously because it's a .wav file. It's a little over 30 seconds long. )
Process of making example file:
I recorded it using Audacity (which is an open source program that can be downloaded from sourceforge.net). In Audacity, I set the recording/input "channel" to be "Wave Out Mix". I turned the Wave out volume and the master volume all the way up, then pushed record. (Turning the Wave volume up caused additional fuzz, so concentrate on the contrast between the sections of the recording to hear the actual sound I'm referring to.) It's a pretty quiet track, so you'll probably have to turn the volume way up.
It's a 30+ second clip. Here's how the seconds break down:
For the first five seconds, I just did nothing.
From seconds five through 10, I clicked and held down the Genre scroll bar in iTunes.
From seconds 10 through 15, I did nothing again.
From seconds 15 through 20, I clicked and held down the Artist scroll bar in iTunes.
From seconds 20 through 25, I did nothing, once again (I kept doing this so you could hear
the difference).
From seconds 25 through 30, I clicked and held down the Album scroll bar in iTunes. (Notice that this one seems to be slightly higher in pitch than the noise from the previous two scrollings I did.)
The last couple seconds, I did nothing again.
More weirdness:
Changing the volume on my computer (both the master mix, and the wave out mix, and any other mix that exists (e.g. line, microphone, CD Player, Mono out, etc.)), or even MUTING the volume of any of these mixes does not make the sound go away or change in volume at all! It's always at the same volume no matter what I do. I can only make it go away if I unplug my headphones (remember: I don't have regular speakers. If I did have those, unplugging the headphones might only change where the noise is heard.). Changing the wave out volume only affected the recording (which is why I turned it way up. If I turn the wave out volume all the way down, then push record, I still hear the noise coming from iTunes while I'm recording, but if I play the recording back, the noise is gone.
Very bazaar...
Any input anyone?

Called Apple support, they said they do not support the use of iPods in cars, they may have sold you your car kit, but they dont support it. So buyer beware. I have three cars, I upgraded my Nano to 1.1, which is the latest, didnt fix it. I went out and tried it in all three cars, squeals in the Toyota (with Monster Cassette Adapter to Original Radio, hisses in the Nissan (with Audio 3.5 cable to audio jack to after market Sony radio), and works fine in old Mercury (with 3.5 cable to old JVC with audio jack).
So I better take care of the old Mercury.
