thank you.
regarding the java output example i set up the destination stream to
8khz and it works.
but if i try to modify settings like channels, bytes per packet like
show here:
destFormat.setSampleRate(8000);
destFormat.setBitsPerChannel(8);
destFormat.setChannelsPerFrame(1);
destFormat.setBytesPerFrame(1);
destFormat.setBytesPerPacket(1);
destFormat.setFramesPerPacket(1);
and similar..
question: is it just possible to down-turn the rate ?

To do sample rate conversions use the AudioConverter
There's actually examples of doing just this
/Examples/CoreAudio/Java/SDK/Output
I've run conversions from as low a 4K up to 192K through our converters
and
not seen anything like the problems that someone else was reporting -
which
I would guess is a problem in configuring the stream descriptions to
accurately describe to the converter what your source and destination
formats are.
For an example of that see CAServices/DefaultOutput (or some such) that
has
some tweakable parameters to do a range of channels, sample rates, ints
or
floats for source - you can stress test the converters this way for
yourself

i installed the java131 update, but the following class method
(mentioned in the docs) is not available.
AudioHardware.createVirtualSource();
if this problem is not resolvable, is there an other way to convert the
44khz audio down to 8khz ?

sure?
i already have the java developer from 23 feb. 2002. installed.
but the coreaudio.jar's timestamp has not chanced. actually, the
timestamp is 15.feb.2002
i opened a java bug ticket about that 8 day's ago, but only a receipt
arrived till today :)
so i decide to ask the people on this list !
should i install an other update package ? is there a way to do this
update by the system updater ?
