I have recently acquired some audio that is in an .m4a format and I would like to know how to best LOSSLESSLY change them into .ogg .mp3 .wav or .wma.

Can anyone help?

iTunes can convert m4a, I believe. I don't know how good that is, though.

If I recall correctly, wavepad can mess with it. And yes, m4a is fucking annoying and everyone should just stick with mp3 and wav.

Why wav? I was under the impression that it took up a hell of a lot more space than other formats.

Yeah, it does because it's a lossless "raw" format. It's just so commonly used that's convenient and easy to work with; convert it to whatever filetype you want with pretty much any program.

I went through some of the stuff in wavepad, but it's saying that they're corrupted or an unreadable format.

How do I know if it's the program's problem or the music being corrupted?

Convert it with something else. If it is corrupted, then it isn't just the program.

Yeah ok It's corrupted.

Next task... Find a working place that currently has a download/torrent for the album "Between the Music and Latitude"

God why is it obscure music is so hard to find...

Think I found one =D

so you can't play the m4a in media player classic, vlc, winamp, or itunes?

Also, if you're looking for music, youtube hosts a lot for free at lower quality or you can just use google with "site:mediafire.com" added on to the end.

you can't convert an aac file losslessly into any normal audio container. flac is flac, mp3 is mp3, mp4/m4a/m4b is aac, ogg is vorbis, wav is pcm, etc...

The only lossles conversion would be into flac or wav.

Also, mp3 sucks. AAC and Vorbis are vastly superior. the new wma is apparently good too. Anything greater than 128 kbps though has diminishing returns on lossy codecs, and most people can't accurately tell which one is better at those bitrates.

What do you know, VLC can play it haha! I figured if 2-3 programs failed to play it... But nope. VLC is just win. Now how do I go about converting it to wav?

Thanks rockz =)

iTunes can convert m4a to wav.

Audacity can record anything your computer is playing. You just need to crank up the volume a bit on the track after you have recorded before you save as mp3, wav, or ogg.

just download mediacoder or super.

Though vlc probably has a built in converter.

re-recording is lossy, inefficient, and slow.

AAC is a bit annoying wot work with due to patents, which is one reason itunes is even a viable option.
