Hi,

I'm currently developing an app in which I need to loop and process 
audio from a file in real-time.

I can see how to use a Clip however I can't see how to process the audio 
if it's in this format. Is this possible?

What I really need is for the mark() and reset() AudioInputStream 
methods to work. Unfortunately they are not supported on my PC (Windows 
XP notebook with built-in audio hardware).

Is there any way around this problem?

I was thinking that if AudioInputStream is now open source there maybe a 
way to fix this?

Cheers,

Chris

Java Sound does not provide a processing architecture. You should use
AudioInputStreams and real-time playback with a SourceDataLine. As I
suggested in the post to javasound-interest, using FloatSampleBuffer
will be a much more useful way to manipulate (and possibly implement a
list of processors) for arbitrary audio data, independent of how many
bits, the endianness, etc.

Regards,
Florian
