Mp3 and aac file formats

Well, I made a playlist on my shuffle...Then when I was playing it It seemed it skipped over all the aav files and only played the mp3. So when I hooked up the shuffle to the computer all the mp3 files were at the top and the aav were at the bottom! So, After spending some time rearranging the list they're now in the correct order...Is there a setting I did or didn't use?
Thanks

i found this info at this link

iPod calibrates its touch-sensitive surfaces when you turn off the Hold switch. Touching the buttons or the touch wheel on a sleeping iPod at the same time that you turn off the Hold switch causes iPod to calibrate to the capacitance of your finger instead of the air. This can cause iPod to turn on but appear unresponsive when waking from sleep.
i'm thinkiing that maybe the click wheel is not calibrated. also, have you restored the ipod.

MP3 and AAC files mixed in burned Audio CD???

Here is the story. I am new to iTunes and I have a 400Mhz G4 AGP Machine running OS 10.2.8 and have Quicktime 6.5.3 installed. I also have a 93 Gig HD and 512 megs of RAM and a Sony CRX160E iLink CD burner. I was running iTunes 3.0.1 for a little bit and just upgraded to 4.7.1 about a week or 2 ago. Can I mix "MP3" encoded tracks with "AAC" tracks. I think that I read in the help menu that I had to use the "Data CD" option instead of the Music CD option. But, if this is so, can I still play this CD in a regular CD player? since was encoded with MP3 and AAC and it is formated as a Data CD??? The reason I am asking is because I encoded a bunch of songs as MP3s in 3.0.1 as default and I understand that AAC files are of slightly better quality so, I wonder if it would be worth it for me to re-import my songs in "AAC" for consistency. Consistency is my main concern. I want to be able to burn CDs with little problems (although I have some issues but, that is a different story) and mix formats if I can.
Thanks,
Larry

Thanks for your help! I just burnt a CD with mixed formats and it played fine in a "newer" CD player. My home CD player is older (Circa 80s or 90s?) and I have been told that the older CD players either can't or, don't like CDRs. So, it played fine in my son's newer CD player but, not in my "older" player. I am not too sure about the difference in sound quality yet. I'll have to do some more testing. The MP3 files and AAC files both sounded well when played. One annoying thing, though is the volume issue. Most of the songs played at a similar volume but, one played quite softly. An annoying thing but, I understand that even if you use the "Sound check" option, the sound can vary due to the fact that iTunes has a "fast" way of reading the sound levels and could be inefficient. I will try "iVolume" to see if that helps. It is supposed to be pretty good for iTunes except for the version 7 that just came out.
Thanks again,
Larry

HT1589 Why does creating a new library only look for mp3 and AAC files. why not ALAC and AIFF ?

I want to add a new library so i can use on sepcific devices. However it does not att AIFF or ALAC files. I always import using AIFF into my standard library.
If i want to use only mp3 files in the new library do i have to create them first in my standard library then they will appear in the new library. then delete from the original library but keep files?
Thanks

Then it may have stalled, ot there could be permissions problems... Try adding the folder again or use iTunes Folder Watch.
Also i dont want to downsample to 128k. i want to use 320k and still have best quality without using lossless formats to put on the iPhone
iTunes can now downsample to 128k, 192k or 256k...
Also i dont want to see 2 of each song in one library
thats why i want to use two different libraries.
Yep, that bit I get, but switching in and out of libraries and trying to keep things up to date is easier said than done. I'm just trying to point out there might be an acceptable alternative that is easier to manage.

CBR MP3 and AAC issue for audioqueue

We are exporting MP3 and AAC files from Logic Pro / Itunes with a constant bit rate - however when we look at these in the terminal they are showing as having a 0 value for the bytes/packet - therefore the SDK is seeing them as VBR files... Here's an example in the terminal:
File: introduction.mp3
File type ID: MPG3
Data format: 2 ch, 44100 Hz, '.mp3' (0x00000000) 0 bits/channel, 0 bytes/packet, 1152 frames/packet, 0 bytes/frame
no channel layout.
estimated duration: 246.000 sec
audio bytes: 4938188
audio packets: 9452
bit rate: 160 bits per second
packet size upper bound: 1052
maximum packet size: 523
audio data file offset: 4096
optimized
Tried exporting them as AAC and MP3 using both Logic Pro and iTunes but all output files are showing a bytes/packet value.
Does anyone know how we can ensure that the CBR files have non 0 values for both bytes/packet and frames/packet?

Here's some more details on the file: Looks like there's a lot of different bit rates in there:
FO:
MPEG1 layer 3

I have a song that is in the following format: 256 kbps, 48 kb in size, and an AAC file format. Why is it tagged in imatch as ineligible?

I ended up reformating the drive as FAT32 because I still need to use it on my Windows 98SE system also. I did have a problem with the allocation size. I wanted to use 512 bytes but it kept failing so I used the default size(8192 bytes) and then it worked fine. I didn't think there would be a problem formatting as NTFS but since you are having problems I just tried it. It failed at 512 bytes allocation size so I tried again using 4096 bytes, the default, as the allocation size and it failed again. It looks like these drives will not format as NTFS.
Also, I think I figured out what's going on with the ReadyBoost problem. As I said initially it wouldn't work with ReadyBoost then after I had 12GB of data on the drive the ReadyBoost feature started working. After I deleted all the files it quit working again. After doing some reading on the net about Flash drives and ReadyBoost problems it appears that the memory chips on my Lenovo Flash drive are mixed with both fast memory chips that work fine with ReadyBoost and slower memory chips that are too slow for ReadyBoost. Apparently, after I fill up the portion of memory with data that uses the slow chip(s) then ReadyBoost works fine with the fast chip(s). I also verified the Flash drives read and write memory speeds using Vista's Event Viewer. To work with ReadyBoost the Flash drive has to read at a minimum of 2.5MB/s (for 4KB random reads) and write at a minimum of 1.75MB/s (for 512KB random writes).
Let me know what you find out.

AAC File Format

I am in the process of deciding whether or not to buy an 4GB Mini Ipod. Could someone please tell me the sort of file sizes the AAC format takes up at different bit rates.
I currently have a Sony ATRAC CD player. I have the music on it in sonys own format ATRAC at 64Kbs and I think the quality of it is okay and I can get around 300 tracks on one CD.
What quality would you recomend I encoded tracks at for an Ipod and realistically how many tracks could I hope to get on an 4GB Ipod Mini.

This was originally posted by the incredible Sparky the wUnderdog with help from MacMuse:
As a general principle, you can fit more CD's on your iPod if you encode at lower bitrates (making smaller files), but at the cost of audio quality. Apple Lossless promises to capture all the data on the original CD (thus preserving quality) but coded so the file takes half the space. MP3 and AAC (an implementation of variable bit rate MP4) both eliminate some of the information on the CD in order to compress the digital recording into ever smaller files--the lower the bitrate, the smaller the file, but smaller files mean more information lost and consequent poorer sound quality.
AAC files ripped in iTunes certainly sound better than its MP3's, with audio quality close to the best LAME MP3's at higher bitrates. With the type of music I listen to most often, sound quality declines substantially as bitrates fall below 256kbps, but LAME or AAC @ 256kbps sounds pretty darned good, and at 320kbps LAME alt-preset-insane is amazingly faithful to the original. However, many users claim that with the music they listen to they can't hear the difference between 192 or even 128 kbps files and the original CD source, so they naturally choose lower bitrates to fit more "songs" on their iPods.
CDs take approximately 10MB per minute of music; Apple Lossless takes 5MB/minute; LAME insane takes 2.5MB/min; AAC or MP3 at 256kbps take 2MB/min; and iTunes Store files (AAC@128kbps) take 1MB/min. At these rates, a 20GB iPod (really 18.6GB) can hold anywhere from 30 hours to over 300 hours of music. (iPod marketers express this potential playback capacity as "songs," figuring 4 minutes per song--thus 300 hours at 128kbps = 4500 "songs.") You will need to listen to samples ripped with different bitrates and codecs to determine the optimum tradeoff point for you between quality and quantity. It's worth taking some time to do this at the start as it sure beats reripping everything in your collection 2 or 3 times to get it right later.
So far as convenience goes, nothing beats iTunes's one-step process. To change bitrate as you import from CD, go to the iTunes menu>Preferences, select the Importing tab, choose AAC or MP3 encoder in the "import using" selection box, then choose "Custom" in the "setting" box, and the window permitting bitrate selection will pop up. If you choose iTunes MP3 encoder, at least use VBR (variable bit rate) to maximize the sound quality. (VBR increases sample size as data complexity increases.)
If you would prefer LAME MP3's, fear not, for the easy-to-use CDex ripping software is a free download and requires only one simple extra step to get the files into iTunes for transfer to your iPod. Now if AAC sound quality is comparable to LAME MP3, you might wonder why you should even consider LAME: Because of portability to other devices. At present, hardly anything but iPods can read AAC's or Apple Lossless, but almost everything reads MP3's. So if you plan to burn CD's of your compressed files for playback on your home or car CD player (for instance), it would be wise to choose MP3.
One other consideration specific to the iPod- It has a 32MB cache (If you don't know what a cache is, read the last paragraph of this page: iPod + iPod Mini- Batteries). Keep individual file sizes below 25 MB as the rest of the 32 MB memory holds the iPod's Opperating System. If you choose a compression rate that results in large files (i.e. Lossless), then the cache won't hold very much 'music' and the hard drive will have to spin up frequently to fill it, and that will shorten your battery life somewha

Mp3 and AAC (unprotected) in FCE 4??

Hi,
I couldn't find any mention in the Apple documents. Does FCE 4 finally support mp3 and aac audio files??
Thanks,

Well, I got FCE 4.0 and it doesn't appear to accept my aac files.

WMP will play some mp3 and mkv files to my Sony TV but not others

Hi,
Windows Media Player will play some mp3 and mkv files to my Sony Bravia TV (KDL70W850B) but not others. I get the error: “Failed to retrieve media information”. Sometimes if I make a copy of the files that don’t play, I am able to play the copied files.

I have stopped and restarted the Windows Media Player Network Sharing Service and the UPnP Device Host Service; I also linked a Windows Live ID but this did not help. All devices have access to my PC and my TV has the latest software.
I have Windows 7 and WMP 12 and according to my TV specs, the DLNA supported formats are: MPEG1/ MPEG2PS/ MPEG2TS/ AVCHD/ MP4Part10/ MP4Part2/ AVI(XVID)/ AVI(MotionJpeg)/ MOV/ WMV/ MKV/ WEBM/ 3GPP/ MP3/ WMA/ LPCM/ JPEG/ MPO
I would appreciate any help you can offer.
Thank you

It seems to be an issue with Sony Bravia TV. According to the following article:

Walkman app not showing my downloaded podcast mp3 and m4a files

Hi all,
Hope someone can help me with an Issue on my Z3 Compact running Lollipop 5.0.2 firmware.
I have a Music folder on my SDCard which contains all my music files in subfolders and all these files appear in the Walkman app just fine.
I also have two folders called 'Podcasts' - one on the internal storage and one on the SDCard which contain mp3 and m4a files which I have downloaded using 3rd party apps.
I would like to listen to these podcast files using the Walkman app - but they will not appear in Walkman - even if I try the Folders options.but it still will not show either of the Podcast folders.
The weird thing is it lists voices and sounds / voices rom two different SatNav folders which are stored on the SDCard - but not the podcast folders!!
It even lists a folder of foreign language audio mp3 files - but not the podcast files.
The podcast files appear fine in PowerAmp whic even shows the tags and descriptions etc....So, why not Walkman?
I even tried unmounting and re-mounting the SDCard to see if it would rescan - but still nothing.
Any ideas?
Thanks!
Solved!

Change in AAC file format?

I have a 3rd party music player (the Archos 604 WiFi) with the podcast plug-in (which includes support for non-protected AAC files). I can play AAC files created (i.e., ripped) with iTunes 7 just fine, but it has trouble with AAC files created with older versions of iTunes. Has the AAC file format changed? Is there a way to convert older AAC files to what seems to be a newer AAC format? I don't want to have to re-rip my entire library (26 GB) again when I am not even changing the format.

It doesn't matter which adapter you are using that approach will work. Any custom modification of the output column order which overrides the calc sequence can be done in the Export Action script. Be aware though that any changes to Action script will affect your support agreement with Oracle if you have one. Therfore it may be best to put any custom output in the AftExport event script.

Illustrator CS3 Import and Export File Format list?

Hello,
Has anyone typed up an updated supported import and export file format list for CS3? I used to reference a support knowledgebase document, 1001741, (no longer on Adobe's site) that showed the majority of file formats and versions that Illustrator was able to import. I searched all over and couldn't find one, then called support and they confirmed they no longer had a list like that available--they had split the import options into separate lists--like what versions of Photoshop files, what versions of .eps files, .tiff files etc. Illustrator CS3 could open.
The reason I was looking because I wanted to see what version Corel file CS3 could open after I was not able to open a customer's v.12 .cdr file.
Thanks,
Rick H.

I am pretty sure that the last supported version of Corel that AI can open is version 10.

Save as PDF, HTML and CHM file formats

Is FrameMaker capable of saving in all three of these formats: PDF, HTML and CHM file formats? Would InDesign be a better choice?

The first two, yes. For Compiled Help, the third, I'm sure you know that the files have to be compiled, so no, and I don't think the source files for compilation are a direct export either, unless you can follow an XML path. Although the popularity of CHM is way down from a number of years ago because HTML is more portable, but that's a different issue.
If I were you, I'd look at MIF2go, a Frame add on that does support export to all these formats, and a number of others.
InDesign doesn't do this either...
Just as a word of unasked for advice, choosing your authoring platform by what it can output is a back-asswords way to choose a tool. Find the tool that suits the way you create documents the best so you get more required features to create your stuff quicker and easier.
Both the tools you mention and most other modern ones do pretty open-ended output, either directly or through filters or conversion utilities... there are always ways to massage output to a different format. So output is certainly a consideration, but it's a relatively minor one.
As for input tools, you're comparing apples and oranges with FM and ID. FM excels at book style documents with multiple chapters or files that share common layout characteristics. InDesign excels at shorter documents that are usually design-driven, that require hands-on layout tweaking, and it can't do multiple file management.

How do I "Add MP3s and ACC Files?"

I can't find the "add MP3s and ACC files" function on this new Itunes. It's stupid, but what can I say? Can you help?

Thanks, but this version doesn't have "import files from folders". I've checked it all. Any idea what I'm doing wrong?
Thanks!!

Does apple store the .mp3 and other files I've purchased 'in the cloud'?

Does apple store the .mp3 and other files I've purchased 'in the cloud'? I had to restore my PC and forgot to back them up. If not, I assume I would potentially need to purchase them again, right? Please help.
THIS IS REGARDING THE iTUNES Client Application V10.9.
Thank You,
The Technology Diva
