Please recommend audio transcoder / converter

Hi there,

I have several high-birtrate mp3 and wma files I'd like to convert to AAC for my iPod. Can someone please recommend a good utility to do this on Arch? Thanks!

Thanks, getting errors from FAAC though. Nothing against CLI tools but... anything with a nice GUI interface?

Last time I checked FAAC from the repos can't produce mp4 files; It's spitting out mp2 audio.

Audacity is one of the best, and very easy to use.

I believe that what you have is raw AAC, not MP4.  Do you get this with faac --help?

MP4 specific options:
  -w        Wrap AAC data in MP4 container. (default for *.mp4 and *.m4a)
  --artist X    Set artist to X
  --writer X    Set writer to X
  --title X    Set title to X
  --genre X    Set genre to X
  --album X    Set album to X
  --compilation    Set compilation
  --track X    Set track to X (number/total)
  --disc X    Set disc to X (number/total)
  --year X    Set year to X
  --cover-art X    Read cover art from file X
  --comment X    Set comment to X

Oh yeah, this is encoded with a patched version of FAAC:

Wake Up And Dream > file Providence.m4a
Providence.m4a: ISO Media, MPEG v4 system, version 2

Interesting. And here I thought it was just for recording/mixing. Wish it wasn't so ugly xD
