Hi,
I just ran through my emails and there are actually a few issues with
JASS. First, it does not any longer uses the original native library
that they developed... it uses Javasound. So it just won't help. Also,
they have a strange license, not FreeBSD, not GPL, so, doesn't look that
good after all.
I'm not sure what you mean by "C code generation". Are you referring to
building a native library?
Thanks,
++ js

Yes, I've been frustrated by this as well...
Unfortunately, Christopher's suggestion of changing the transferSize
of AudioPlayer hasn't ever solved the problem for me...
JASS looks promising... Please let us know if you make
progress here. However, I suspect that to get really
reliable performance, C code generation is probably the only
really effective way to do this effectively...

Hi,
I'm trying to build an application with PtII that can:
1- read audio files
2- extract raw information (ie. amplitude) to control something else (like,
say, the intensity of a light or the saturation of a video)
3- play the file
I can do (1) and (2) pretty easily with the AudioReader actor BUT if I plug it into the
AudioPlayer the sound output is really poor. Even with this very simple app (AudioReader
-> AudioPlayer) I can hear "clicks" indicating a poor latency (and unacceptable
for a media application).
Christopher pointed out a long time ago that the C codegen facility had an
interface to Simple DirectMedia Layer. Could that be a solution? What about JMF?
