[Audio-engine-dev] Suggestions to completely Free the JavaSound implementation

[Florian Bomers]

I agree, it's not of benefit to use aggregated audio engines, or
underlying porting layers, because Java Sound /is/ already a
porting layer.

Rather, I'd use
- a software synth that can be freely assigned to a
SourceDataLine (see my other post)

- plus any number of different mixers giving access to the
different native audio architectures, e.g. mixers for
- ALSA
- Jack
- Windows DirectSound
- ASIO
- MacOS CoreAudio
- OSS
- Solaris Mixer

I also propose a software mixing mixer that mixes all its
SourceDataLines together and writes the sum to a selectable
Mixer. This mixer can then be the default, so that applets,
games, and the like can just play without worrying about mixing.

And last but not least, since there seems to be demand, we can
easily add seperate mixers for
- ESD
- PortAudio
- PulseAudio (haven't heard of it before)
- [k]artsd
- gstreamer
- and mixers for the hundreds of other audio porting layers and
audio daemons.

The openJDK can easily integrate all the bindings and they'll
just work if the underlying architecture is available/installed.

Later,
Florian
