Salutations David for on the 11 Mar 96, verilly did you scribe;
DN> Unfortunately a DSP is not magic. 1 channel of 48Khz 16 bit sound is
DN> 96K/s. Assuming your samples are spooled from hard disk, Zorro-II can
DN> only transfer a max of 2.5 MB/s, which limits you to about 25 channels
DN> and that is assuming that your drive have no seek time as they swap
DN> between 25 mono AIFF files. Ie 16 will be your max. At 16
DN> channel your bus will be close to saturated (that is why Sunrise was
DN> only 8 channels).
Assuming you don't use some nifty more efficient method to store your
samples of course...
DN> That is the main reason the Audio card I have been working on is
DN> Zorro-III. Bus saturation is a very important thing when you are

Ah ha. Sounds interesting. Personally I think we need a CyberSFX RTA system
and a relatively cheap multi channel sound card for the Amiga. Just this
with Octamed Sound Studio support would make the Amiga a killer audio
platform again.
