- Unfortunately a DSP is not magic. 1 channel of 48Khz 16 bit sound
- is 96K/s. Assuming your samples are spooled from hard disk, Zorro-II
- can only transfer a max of 2.5 MB/s, which limits you to about 25
- channels and that is assuming that your drive have no seek time as they
- swap between 25 mono AIFF files. Ie 16 will be your max. At 16
- channel your bus will be close to saturated (that is why Sunrise was
- only 8 channels).
-
- That is the main reason the Audio card I have been working on is
- Zorro-III. Bus saturation is a very important thing when you are playing
- back 8MB/s video at the same time. The product is called SoundStage
- by Applied Magic Inc. Currently all developement is focused toward
- Video and Audio combined editing, although developer for stand alone audio
- tools are welcome.
