dmpa decodes MPEG-1 layers I, II, III audio files
Res upcoming user interface...
AC3Train MPEG audio file (layer 3 bitstream)
cmpa create your own mpeg layer II and III streams (slow)
Examples
========
When used with !Player (select: signed linear 16bit, Stereo, 44100Hz).
dmpa AC3Train ram:decod/pcm
Use -x to change the order of samples (some other programs)
dmpa -x AC3Train ram:decod/pcm
Use -p for direct audio (StrongARM recommended. Note: you must have 16bit audio)
dmpa -p AC3Train
dmpa -p -v 50 AC3Train
Note: SoundCon doesn't handle 16 bit audio correctly!
How to create your own streams with cmpa
========================================
To create layer II stream: cmpa -l2 -b128 Sample l2p2b128
and layer III stream: cmpa -l3 -b128 Sample l3p2b128
Note: cmpa contains BUGS!
History
=======
DMPA:
0.23 some bug corrections and ~3% faster
0.22 optimisations ~35% faster than version 0.20
volume option added
0.20 new audio handler
Icon and improved user interface ;-) (Manuel Tims)
0.05 ESC key now stops playing
0.04 ???
CMPA:
0.10 First one with version string
ToDo
++++
DMPA:
- correct layer II volume (~75% from MAX currently)
- make it into a module
- 2x play mode (FF)
- Desktop interface
- support for 8bit soundsystem
- Optimise
CMPA:
- integer FFT and sin/cos transformations
- try to correct layer III encoding
- really optimise
