- 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
