Convert AAC to AC3?

I have HTPC connected with HDMI to AV Receiver and then it's HDMI out connects to TV.
On my HTPC I have few .mvk and .mp4 files that have AAC 5.1 sound tracks, however I have a problem to sent them over through my AV receiver. Whenever I try to play a movie with AAC 5.1 track, it always breaks up once in a while... plays a bit and then breaks up for few seconds or a minute and then plays again...
Can I convert AAC to AC3? So that my HTPC doesn't have to do it on the fly.

I don't see why you wouldn't be able to. While I hate to give cryptic answers, the best I can suggest is to do some research into using ffmpeg and/or mencoder. Probably either of these programs could do it, but if you can only go with one then my vote's with ffmpeg.
I can't be any more specific, sadly. Both programs are a little hardcore for me, and the best I can do without a reference is ripping audio out of a video file (creating an mp3).
You might be able to get away with using Handbrake or something if ffmpeg / mencoder seem daunting. It's worth a look, in any case.

Converting AAC 5.1 to AC3 5.1

Unable to convert aac (m4a) to another format

I have hundreds of m4a files in iTunes, and I want to convert them mp3.
however every time I try, I get an error message
"Error occurred while converting the file "myFileName". The disk could not be read from or written to."
now, I know you'd generally think that my permissions are set incorrectly, but I've checked that the files have read/write access.... I even tried converting them to WAV and AAC instead but same issue. Weirdly, MP3 files in the same folder can be converted to another format.
I tested converting a problem AAC file outside of iTunes using 3rd party software and it worked.
It seems to be that my AAC (mp4a) files are being stubborn inside iTunes. anyone know why?

First, M4A stands for MPEG 4 Audio. It's an AAC file inside an MPG envelope. AAC is the successor of MP3, providing better quality at lower file sizes. In addition, people distributing content don't need to pay royalties to use AAC.
To convert these files to MP3 files, there is two ways for you:
#1. go to into the Preferences panel of iTunes. Click on the orange "Importing" selection and then select an MP3 Encoder for importing. Change the settings to whatever you want. Now, click OK and go back to the main window of iTunes. Select all songs you want to convert to MP3 and click on "Advanced" -> "Convert Selection to MP3".
iTunes knows a second AAC format called M4P. This is the protected version. It cant be converted to MP3 as easily. If you want to convert it to MP3, do this: First, burn the songs you want to convert onto an Audio CD (preferrably an CD-RW so you can erase it again afterwards). Now, import those songs again, this time into MP3 files.
#2.you can use a video converter software, here i recommend you Leawo Video Converter,this video converter can help you to convert aac audio format to mp3 files easily. You can find this software here. http://www.leawo.com/leawo-video-converter/
wish ican help you!

How do I convert AAC files and put them on my SD card

Hello all,
I'm trying to convert some of my itunes track unto my sd card and then play them with my zen. ? The problem is I can't figure out how to get zen media explorer to put the converted files on my sd card. Does anyone know how to overcome this problem? Any help and information is very much appreciated.

Yes, they do. What they don't answer is "How do I configure <insert random media management application> to convert tracks between different audio formats and DIRECTLY store the converted output to the SD card I have installed in my Zen?
Why not? Because it isn't really possible. The internal memory of the Zen and the SD card contents are completely distinct storage areas and are not simultaneously visible to the host computer. You either have the Zen in MTP mode where you can interact with the internal memory or you have the Zen in Removable Disk mode where you can interact with the SD(HC) card. It is an either-or proposition. So you must (a) convert your music files to a location on your host computer, (b) put the Zen into Removable Disk mode, (c) transfer the converted files to the SD card and then (d) restore the Zen to MTP mode (where you can use the Memory Card menu items to browse/play the files).
I suppose I could pull back on the "not possible" part a bit since a stand-alone audio converter should allow you to set a user-specified output folder. As such you could put the Zen into Removable Disk mode first and then configure the converter to send files to the approriate folder on whatever dri've letter the SD card gets mapped to.

I think I want to start with (a), now can I use Zen media explorer to convert the files and place in another location on my computer or I must I download a 3rd party application to do this?

How do you convert audio to ac3 in DVD SP 4 without a.pack

how do you convert audio to ac3 in DVD SP 4 without a.pack
thanks

NO. If you let DVDSP make your encoding you'll get uncompressed audio (AIFF/PCM) what means most probably high bitrate issues during building/playback and a lot of the space of your disc.

How to convert AAC to MP3 in iTunes

I sent a friend of mine a song in the AAC format; I had thought that format was universally acceptable. Unfortunately, my friend said that she couldn't open the file. I then thought of converting the file to the MP3 format, because I know she can read that. This gets to my question: How do you do it? When I highlighted the song and clicked on Advanced, the only option was to convert to AAC. That's when I decided to come here. Is there a way to convert AAC to MP3 with iTunes? Also, how widespread is the acceptance of AAC?

You got the process correct, it
is just that iTunes only offers you the option to
convert to whatever your preferences are currently
set to for importing.
So go to preferences, importing, set it to MP3. then
go to your song and you can now use the "Convert
to..." option which should show MP3. Once done, go
back to preferences and switch back to AAC if that is
what you normally want to use.
Patrick
That was fast. Anyway, it worked. Thanks for your help. Now, all I have to do is to work-out what combination of factors I should use to obtain the smallest possible MP3 file while maintaining decent quality. It's an individual decision. What would be okay for me, might be intolerable to others, but I want to keep all sound files less than 1 MB. Make that, "all sound files that I send". I hope that doesn't mean that I will have to keep duplicate files. We'll just have to see. Anyway, thanks again.

Convert .aac files to .mp3 in itunes 11.0

How do I convert files from .aac to .mp3? I've changed my 'import as' settings to .mp3, and when I select a file, and click File->Create New File, all I can select is .aac format.
Thanks.

Janice.
You can convert AAC files to MP3 by using the Advanced > Convert menu. However, you must first go to the Preferences > Advanced menu and change "Import Using AAC Encoder" to "Import using MP3 Encoder". This setting is used for both importing and converting. When you are finished converting, change the Preferences setting back to the encoder you prefer for importing.
You can burn an MP3 CD if your CD player can play that format. You can fit a lot more songs on an MP3 CD than an Audio CD, but not all CD players can play an MP3 CD. Just go to iTunes > Preferences > Advanced >Burning and select the type CD you want. Note that songs must first be converted to MP3 format to burn to an MP3 CD. If your songs are in AAC format, iTunes converts them on the fly to AIFF when burning an Audio CD, but cannot burn them to an MP3 CD unless you convert them to MP3 files first.
Hope this helps.

Convert AAC files to MP3 in iTunes?

On my Mac, I can download from the internet in either MP3
or AAC. I can also change MP3 files to AAC. But, can I
change AAC files to MP3? I'm sure Apple had me do this one
time to override some iTunes error, but I can't seem to do
it now. I used this MP3 format for a long time so a lot of
my downloaded songs are in this format. Now I'd like to
change them back to AAC because it says I can't make a CD
from MP3 files. Can I change the format or is there some
way I can make a CD with MP3 files? I think I did it before
on my old computer....I MUST have done it before because so
many songs are in MP3 but it says I can't do it on the new
mac.

Converting .wav to .ac3

Hi Everyone,
I have a stereo mix and a 5.1 mix from a pro mix session and I'm trying to determine the proper way to convert them to AC3 files.
The stereo mix consists of two separate .wav files. How can I convert them to a single .ac3 without altering anything that was done during the mix? I feel like I'm missing something obvious, but I've searched the forums and the Compressor User Manual, and I can't seem to find the answer.
The only way I could seem to combine the files in compressor was by using the add surround sound button and manually placing the Lt and Rt channels and then dropping the dolby 2.0 profile on it. I wasn't sure though if by using the surround sound area that I was harming the integrity of the mix.
For the 5.1 files, which are all properly tagged (i.e Lf, Ls, C, etc.) in the filenames, do I use the add surround sound to assign the channel? This one seems pretty clearly explained in the manual, except that I'm using .wav files.
Thank you in advance for your help. Sorry if these are dumb questions!
Michael

The converted file will be saved to the same folder the original file is in. You have to delete the original if you don't want it, there's no setting to have iTunes automatically delete it. Party shuffle isn't a folder it's just a playlist of sorts, it's made up of various songs that are in your library.

Convert DTS to AC3

I have a MKV movie that has DTS for audio, however, my TV only supports MP3 or AC3 for audio playback. Does anyone know how to extract the audio from the file, convert it to AC3, then reattach it to the MKV file?
Thank you.

you need to select the audio clip in the window, under the import window, after it is imported and then below that it will change and instead of seeing the video options you will see the audio options. check the box that says downconvertDTS. You should understand that there is now DTS decoder for the mac and if you are going to use these on your PS3/360 you will need to take that demuxed file to a pc to convert to an AC3 or ACC file for use in an .M2TS file. email me if you have further problems.

Converting aac to mp3 for a cd

Hello
Is t possible to convert my iTunes library (aac format) to mp3 in order to burn a mp3-cd? I couldn't do it, iTunes tells me that none of the songs are in mp3 format. Do I have to bring all the cd's again to my library in mp3-format? There's 7 gigabits of stuff so it'll take a while if that's the case...

Before I go into detail, with store bought Songs from iTUnes, there in a "AAC protected format" and can not be converted, you have to first burn them to a audio CD, then "Re"import them as MP3
For all other songs you will first goto edit>preferences>Advanced tab>importing sub tab and set it to MP3 and the bit rate you choose (Usually a high bit rate is better when converting songs from AAC or other formats)
With that done you can rightclick each song one by one and hit "Convert to MP3" or you can select/highlight one song, hold the shift key, and select the last song, this will highlight every song inbetween the first and last song (More on iTUnes shortcut keys here http://www.apple.com/support/itunes/windows/shortcuts/ ) When you convert songs like this iTUnes will list 2 of the same song, one is the original, the second one will be the converted file

Converting AAc files to mp3

I loaded all my CDs into iTunes as AAC files. There are a select few somgs that I'd like to turn into mp3s to be loaded into another device. Is there a simple way to do this within iTunes, or am I just better off re-importing them (there aren't that many).
Thanks in advance
Steve Denvir

Steve.
If your CDs were imported as AAC files, you can convert them to MP3 as follows:
1. In the iTunes menu, go to Preferences > Advanced and change Import Using AAC Encoder to Import Using MP3 Encoder. That setting controls both importing and converting.
2. Select the song you want converted and go to the advanced menu and select "Convert Selection to MPs". You will end up with both an AAC version (AAC audio file) and an MP3 version (MPEG audio file).
3. After you are finished converting, go back to the Preferences > Advanced and change back to Import Using AAC Encoder.
