Subject: FireWire + Re: [oc] Audio DSP PCI Card for mobile studio
Dear colleague,I found some your remarks as thought provoking in positive terms.
However, phase distortion, jitter, wander and some other effcts are
important when considering audio field. It is our idea to make those
phenome controllabel with FPGA design as it is proved by some
designs that are already in use.
Thus, we prefer FPGA. However, if someone wants to use DSPs
that is fine too.
Best wishes,
Vedran Vucic
