What are all of the audio codecs that are supported under Zaurus?

So far I know of:
  • MP3 (MPEG-Layer 3) - plays on default audio player and most (all?) audio players
  • WAV (Uncompressed) - *gag*
  • OGG (Ogg Vorbis) - plays on "MediaPlayer" after installing special plugin
OGG is roughly twice as good as MP3, but neither of them are very good at doing what I need. I have many audio books I want to listen to on my Zaurus. Previous to my Zaurus I used 5 kbps RealAudio and/or 5 kbps Windows Audio. MP3s can only go down to 16 kbps (and most encoders can only go down to 32 kbps). Ogg Vorbis can only go down to 9 kbps (and forces the file to remain stereo), and even this is only possible if I encode the audio file to an 8 KHz uncompressed WAV file and then encode OGG using the lowest audio quality (this is the solution I'm currently using and the quality is fine for audio books... but it is a waste since it requires stereo even though the source is in mono).

Are there other audio codecs that are supported under the Zaurus through any means, hacks, installations, etc?


Is there a way to encode MONO OGG files (so I can get down to 4-5 kbps?)

Awesome!! smile.gif  I downloaded the attachment above and played the audio samples using the suplied Speex decoder you compiled. smile.gif

Glad to see it worked for you. The executable is just taken from a straightforward cross-compile of the standard speex-1.1.6 distribution, statically linked together with a regular libogg-1.1 library built the very same way using the good(?) old Embedix crosscompiler provided by Sharp smile.gif

The quality of the samples may not be the best, though, since ( a ) I was too lazy to build 1.1.6 for my Desktop and used my existing speex 1.0.3 installation and ( b ) used some old 16 kBps RealAudio source as input, since it was the only thing that I had lying around that was pure speech without some sort of music mixed in. My guess is that using a better quality source the result might even be better.

[...] found that the latest versions of the following programs support ogg-vorbis:
  • mplayer
  • NPlayer
  • Opie Player 2
  • media player vorbis-plugin (this is what I'm currently using)
  • X Multimedia System

AFAIK MPlayer does not integrate speex yet, but my guess is that it eventually will, since people are asking for it on the mailing lists. There is a speex plugin available for XMMS, so it should be a simple task to build it for someone who has an XMMS development environment set up for the Z.

Since I've decided to tinker with VLC, I can only say that speex does integrate nicely there (actually I did build myself a speex-capable version of VLC just yesterday, hence my quick response with the binary wink.gif ) -- unfortunately there still seems to be an issue with VLC playing back 8kHz audio on the Z (dropouts on playback, seemingly independant from the codec used; I'll have to look into that and/or pester some of the VLC people about that when I get the time to do so biggrin.gif ).

4 kpbs audio books on the Zaurus!  Now THAT's what I'm talking about!  biggrin.gif  cool.gif  smile.gif

Well, hopefully you'll find someone who shares your enthusiasm laugh.gif
