Hi Bill,
I tried to generate interleaved multichannel files, especially for our
47 channel sound dome and ran into problems.
I think interleaved files would be better to read for the discs
because the head doesnt have to jump as much.
It looks that the size of multichannel files is limited in absolute
size. Computing those files resulted in shortened sounds-durations.
The more channel there are the shorter was the duration.
Is there any way I could create longer soundfiles, something like
36 channels, 48 (or even 96) kHz, 24bit and 25 minute of duration?
would the counter of the runloop need a to be special format?
The duration limit of the mentioned format is currently limited to a
duration of 8 min53 seconds.
thanks
Ludger
