2-channel audio sounds hissy and low; Each channel by itself sounds good... what?

Hello everyone. I have been having a problem with the quality of my captured audio for a while now. I am not an audio guru at all, so it is hard for me to even explain. So, please bear with me:
My issue is that I import my footage into FCP 7 as HDV 1080i60 with both audio channels active and linked together as a stereo mix. As I play the video in the timeline, the audio has a hiss in the background, and the persons voice that I interviewed sounds like he was "holding his nose shut"(for lack of a better word) while talking throughout the entire interview. If I delete one of the channels, it sounds great... but it is now mono, and it doesn't have the full quality that my lavalier (stereo) microphone supports.
Here is a pic of what the waveform looks like:
Here are the spec's for the audio (thanks to Invisor.app):
ID : 2
Format : PCM
Format settings, Endianness : Little
Format settings, Sign : Signed
Codec ID : sowt
Duration : 5mn 39s 204ms
Source duration : 5mn 39s
Bit rate mode : Constant
Bit rate : 1 536 Kbps
Channel(s) : 2 channels
Channel positions : Front: L R
Sampling rate : 48.0 KHz
Bit depth : 16 bits
Stream size : 65.1 MB (5.8%)
Source stream size : 62.2 MiB (6%)
Now, both channels sound great by themselves, but when joined together create the hissing and high pitched sound I mentioned earlier. Can anyone tell me what is going on? Thank you for the support!!

When you start editing, either only add one to the timeline, and make it mono...or add both and make them mono. Typically when I deal with talking heads, I will use only one channel. Unless I have a wireless mic on one, and a boom on the other...I'll add both, but mute one (the one that sounds worse)...but have both just in case some sound affects the main audio, then I switch to the other.

HP Mini 1030NR Bad audio, very Tinny and low...

I purchased the mini around christmas of last year and I was hoping this would have been resolved but the audio driver is still nothing like I expected. It is far too tinny and low even after it has had the latest updated drivers.
I have been unable to find help online or with tech support. They have recommended trying other driver sites, but they have no direct links to specific drivers and will not support outside audio drivers.
Any ideas?
Everything else about the machine is great!

I have heard this complaint about the MINIs from other people as well. To the best of my knowledge there is nothing really to be done about it. The speakers in those notebooks are about the size of a quarter, they simply do not put out much noise, or very high quality noise. There are speakers of that size that put out better sound, but they cost considerably more, and the concept of the MINI is a ultra-portable notebook for an affordable price, and the speakers are one of the trade-offs. I would recomend, if the sound quality is important to you, putting the money that would have been in the cost of the notebook towards a nice set of earphones or travel-sized speakers.
They may eventualy release a driver that could concievably make the sound better, but no driver will ever be able to change what the speakers are physicaly capable of.
-Good Luck

Audio Sounds good in SP and bad in FCP

Hi,
I preface: Recently i did a clean up of system with prefernce manager and pro maintenance tools.
I just sent an audio file from FCP to Soundtrack Pro (SP) to get rid of clicks. Sounded great in SP but with more clicks than it originally had in FCP. Never had this problem. I'm sure it's related to the fact when i went to export the file from SP after taking clicks out it asked me if I wanted to Reference Source Audio or Include Source Audio. I chose Include Source Audio even though it said in the box that it wouldn't play correctly if I didn't reference source audio, but it said i could change the setting in preferences back to the default. I did change it back to reference source audio, resaved and exported and it still has all those clicks in FCP.
Any help is appreciated!
Thanks,
joe

Hi Mike,
Thanks for your help. I played it in i tunes and fcp today and it sounds good in both, but yesterday it was cracking throughout. I don't understand. Bizarre.
Thanks again!

Audio sounds good on computer but shakey on TV in spots

Hello,
2 hr project. all audio levels are consistently between -6 and -12. Project sounds perfect in fcpx. When exported to dvd and played on a computer it sounds fine, BUT when played on a new hd tv audio at various points in the project make the tv's audio shake just a little.
I used bass boost throughout project cause i wanted a fuller sound. I think it might be that, but short of having to go in and adjust all bass levels i was wondering if anyone knew of a filter in fcpx that normalizes everything so that it sounds good on computers and tvs? i think there's a broadcast safe filter. Will that take care of the problem, or is there something else? A little more detail - my audio levels were originally above -6 consistently via an someone who worked on the projedct throughout entire project. when i moved them back between -6 and -12 i didn't adjust any of the bass boost levels that he originally established.
Thanks for your help! joe

Update....
So far, the video made with iDVD only sounds clear via the computer or surround sound system. The sound is hissing/fuzzy sounding at the "s" and "f" sounds on ALL regular tv speakers that I've tried it on, mono or stereo either one.
I saw the reply that stated there are no audio settings in iDVD with "OneStep..." So nothing can be adjusted in iDVD to make it sound good on all tvs? And no clues as to what's causing this issue?

External Usb Audio Card Popping and Cracking sound with Satellite L500

Greetings,
My name is Boyan and I am from Bulgaria and about an year ago I've bought a satellite laptop from the l500 series ( i can not state which exactly is the model at the moment because my computer is not currently with me and on my user manual the only thing which is stated is that it is for L500/L505/ L500D / L505D . But by memory I think it was the Satellite L500D-ST5506 which is currently not at my dispossal because I gave it for repair for the same problem which I will state down below)
The problem with my laptop is that when I plug a Usb Audio card in my laptop I have a cracking sound when live sound is played trough the speakers/headphones from the external card. I've tried numerous audio cards and speakers/headpohnes which work perfectly fine with other computer, including laptops but the same problem keeps on showing up in the headphones/speakers of my laptop when I am using an external audio card to connect them to the laptop.
The problem is prominent only when the sound signal passes trough an external audio card and it is very annyoing since I use my laptop to create music and i've bought an expenssive audio card and speakers which can not be used with the laptop. I've tried 3 models of audio cards:
M-Audio Fast Track Pro
Behringer uca 222
and a simple external 3d sound usb audio card and the problem still appears.
At first I thought that the problem should be software and I should install new drivers although windows 7 automaticaly recognizes and intalls the drivers for the devices and I have sound in them (but with cracks and popps) so i tried using the official drivers sold to me with the audio cards but with no luck: The problem was still there. I tried finding new drivers of the audio cards on the official distributors websited and i've downloaded them but the problem was still there. Then i tried to delete every audio driver on my computer and just use the external audio card for sound but this dint help eighter. I've updated my drivers for my build-in audio card as well but again - no luck.
After that.the frist thing I did when (2 weeks after i bought the laptop) was to contact the store from which i bought my audio card and they stated that the problem may be eighter latency or high voltage from the laptop so they adviced me to try to lower the latency from the settings or to try and see if the problem remains if my laptop is only running on battery. I've tried both things and they didn't help. The audio cards worked without a problem on every other computer I've tried them on except mine. So they said to me that the problem couldnt possibly be from the audio cards .
What I did next was I gave my laptop to the official distributor of toshiba in my country so they can fix my problem. What they said to me was that the problem is caused from the version of windows which was pre-installed on my laptop and that it wasnt compitable with the audio cards (which was bizzar sounding because I've tried them on the same windows and they've worked, just on other computers). So I got back my laptop and changed my operating sistem from Windows 7 Home Premium 64bit to Windows 7 Ultimate Edition 64bit to Windows 7 Ultimate Edition 32bit and on all of those versions the problem was there: whenever I activate a Usb Audio Card and audio signal passes trough it I heard cracks and popps. I even tried isntalling Windows XP but the laptop wants spesific SATA drivers for the installation of Windows XP which although i did find - they didnt help me install XP and I didn't want to go in to the BIOS of the computer to try to put a new one and so on because I am not so sure about that and I could lose my warranty so I said to the official repair store for Toshiba in my town to put XP on my computer to fix the problem but they can't because they are not liscened to operate with software which doesn't have a recipt for its purchase ( which i didnt because i bought my windows xp long ago and i've lost the recipt)
I gave it for repair for the second time telling them that the change of my operating system did not solve my problem and what they did was they changed the whole motherboard on my computer, stating that the build in realtek audio device on my computer is not good enough to support an usb audio card or it maybe broken and they have to change the whole motherboard because the build in card is glued to it, so they did that but my problem wasn't solved. They told me that although I am using and external usb audio card the signal still passes trough my internal one and I have to disable it so i tried disabling it trough the control panel but this did not solve the problem and i do not have an option from BIOS to disable my build-in audio card. Another thing which I thought maybe causing the problem is that the two audio cards aren't working on the same bit rate and Hertz so I set both cards to 16 bit 48000hz DVD Quality (Also tried other options on the 3 cards i have) but...the same thing happend.
They told me that this is just my luck and that the build in audio card doesn't support this external audio cards and I should had been more careful when choosing my laptop at first.
I couldn't accept this awnser for several reasons:
1) This audio cards work on lower version of windows and are supported by much older models of Realtek and much older computers (one of them was bought 2000!!!!! and my laptop is from 2010!!)
2) The guys who were fixing the problem apperantley didn't go in so deep in to my problem because they didn't know what actually the problem was they just knew that there is a problem with the audio card and the computer interacting with eachother, they didnt know that there is cracking during live play from the external audio card.
3) I can not accept the fact that Toshiba is manufacturing models with chipset audio cards which can not support a simple external Usb Audio Card. This is totally unacceptable for me and I truly hope this is not the case!
4)They didn't try my audiocards on an other laptop from the same series stating that they do not have one at their dispossal at the moment so I will go tomorrow to a local store and try the audio cards by my self on the same computer in the store.
What I did now was I gave back my laptop for repair asking for a statement of the problem in wrtting with all details of the problem so I can go to court or ask for a new laptop but I will be charged with some money because according to them there is no problem in the laptop and the problem is that my external audio cards arent compitable with the build in internal chipset audio card. If I give my laptop for repair and there is no hardware problem I will have to pay some money. I will do this but I am now mad, since this will not solve my problem and I am loosing time and money.
What I am asking here is, if you can not help me solve my problem and advice me what to do to fix it, please provide me the details of the chipset build in audiocard on my motherboard, so i can investigate if it is compitable with my external audio cards and contact the audio card dealers to ask them for their opinion. Or if you can tell me with what it is compitable with and with what not, it would be great. I personally think that this laptop should have no problems at all with running a simple external usb audio card but I am asking you, if you know something more about that.
If the problem is from the build in chipset then Toshiba is manufacturing (or at least selling) audiocards which aren't at a normal standart but sadly I cant do nothing about it except complain to Toshiba and never deal whith such productgs anymore. In the other case if this is not true, then my laptop has a problem which is different and I will have to go to court with the repair mans for not fixing my laptop or not giving a new one when I have warranty which will not be Toshiba's fault and It will in a way solve my problem.
I hope you understand how Important this is for me and I hope I resolve the problem as soon as possible.
P.S
I would like to state that I am well aware of the grammar mistakes I have made in the text below and I would like to ask for your apologies as I am not a native English language speaker.

hi i just like to say i had a similar fault though i would be surprised if it causing yours,but you never know,my fault was my laptop lid, [9 months old] it contains the mic ,and when the lid was in a certain angle crackles could be heard worse when i had my external sound card in, it was a faulty membrane [ lid to body] easily missed by engineer because it was the same angle all the time it happened,good luck, PS you English is very good

Audio sounding Dull & low - After export

Hi there,
I'm editing in Premiere Pro CS4. If you see the images below, it will tell you a bit more about the system and settings I'm using. I gave my customer a DVD and she complained about the audio. I asked her to email me the description of what she wasn't happy about, and she wrote this: 'with the audio the sound quality was lost it wasn't crisp and clear. And the base and beats were very low. Came out as very dull sound'. Now I agree with her. One of my fellow editors who uses another system produced a video, and imediately I noticed how wonderful the sound was. I could feel the base and hear more of the instruments.
My original audio peaked like this:
I asked someone what was the best level to put it at and they said let it peak at -6. So now my audio peaks like this:
After the complaint, I asked a few more people, and they said that the green level of the audio should be reaching level 6. So now my audio peaks like this:
Now I'm not sure if the above settings have fixed the problem, but at least on the computer it sounds better.
This is the version of Premiere I'm using:
This is some info about my computer:
File properties before export:
File properties after export:
Project settings:
These are my export settings:
I hope this is enough information and I appreciate any help. Let me know if you need me to gather more info.

haha very funny.
Certainly not. :-) I've actually noticed it even before she mentioned something to me. Maybe I'm mistaken. You sound as though nothing should be wrong with my audio. Is that right? Judging from my settings.

When I record video on my iphone 4 the audio sounds like it is muffled and is not as loud as it should be?

when I record video on my iphone 4 the playback of the audio sounds like it is muffled and is not as loud as it should be? I have had the phone for 2 years and the last time I had used it to record a video was in July of this year. The sound came out crisp and clear. Now when ever I play back videos the audio is muffled and at a lower volume than it should sound like. I have the volume set all the way up when I record and my hands are not covering the microphone and/or near to affect the audio playback.

It worked!!!!! Thank you. I didn't know there was a microphone at the top. I knew the hole was there but I didn't know what it was for. Thank you so much. \m/ ROCK ON!!

My audio/sound has been erratic for a while and now I have no output Help!

My audio/sound has been erratic for a while, both output and input, sometimes one would worked but not the other and sometimes both would be none excitant.
System preference does not show what I have connected aka external speakers or headset and the sound output in menu is grayed plus the output on system preferences output as well, sound input looks ok now.
Had Tiger, so I upgraded to Leopard to see if that would helped, Output use to come back after a while, however now input works but output hasn't worked for days, I can hear sound when I am rebooting or starting the computer, but its gone right after.
Since the Mac its fame for their audio stability, no ones seem to know how to solve the problem, so I am kinda desperate.
I have tried the following; ran repair permissions, looked for fluff lol!....still cannot fix the glitch. Any new ideas please!!
Thanks in advance!

Since the problem existed before installing Leopard, it is clearly a hardware problem. Updating a broken system does not fix it, in fact many times it makes it worse or at least harder to diagnose.
I suggest you repost in the appropriate hardware forum - in your case the G4-17 forum(s) here:

and the general G4-17 forum here:

Hi Brian,
Thanks restoring and restarting didn't fix my problem - i have started it fresh and still it doesn't work. Basically I press ONCE on the remote, after the machine has not had any commands for 10 minutes, and the cursor skips from one end of the menu to the other - so I can't choose network or update software etc - I sometimes manage to stop it randomly in the middle of the menu if I press on a command in the middle of the cursor skipping all the menu steps...not sure what the problem is but I have basically not used my brand new apple tv since I bought it for that reason! I should call Apple support I suppose! grrrr hate wasting time with stuff like this!
Thanks for your help though!

How can I record an audio sound and convert it to a ringtone?

How can I record an audio sound and convert it to a ringtone?

Record your voice using iPhone (for ringtone only 35 secs or under are valid), sync iPhone with iTunes.
In iTunes the recorded voice is listed under Music as some_numbers.m4a.
Right click on the item and choose Create AAC version.
Drag the converted voice onto the desktop.
Delete the voice copy in iTunes. (important step)
On desktop, rename the some_number.m4a to something_more_intelligent.m4r
Drag it back to iTunes and you will find it under Tones.
Now select it (for sync) and connect your iPhone, do a sync.
If everything works out, it will be in Settings > Sounds > Ringtone.
Now choose a contact you want to assign this ringtone, tap Edit and add the ringtone.
Hope this helps.
