[Audio-engine-dev] Audio Engine: Windows support

[Florian Bomers]

Hi Alex,

it's clear that you're a newbie, and that's not a problem, Java
Sound development needs everybody! you got Mixer's and
AudioInputStream/AudioOutputStream a little mixed up... of course
all access to soundcards goes by way of the Mixer and DataLine
interfaces.

One very good approach to identify weak parts of the API is to
write (the audio portion) of a real application. jsresources.org
provides a wide array of full apps and small example programs
which you can examine and take as basis.

Another approach, currently, is to work on Tritonus and then
later on, transfer the new implementation to Sun's JDK when it's
opened. Tritonus is "owned" by Matthias Pfisterer and me, so it's
easier to get something into it and especially out to people.

I know people ask for FLAC support in Java Sound, that would be a
nice opportunity for a tritonus task. Or ID3 tag support, VBR
header, and (re)wind support for MP3 files. Or
AudioFormat.properties support for Wave, AU, and AIFF file
readers. GSM support for wave files. Such tasks can be easily
ported to Sun's JDK once it's open.

For other tasks, some knowledge in the respective field would be
useful - what's your programming experience with digital audio?
What about DSP?

Regards,
Florian
