Audio I/O demonstration

Welcome to the prototype audio control panel! Sorry about the formatting, but this will be fixed sooner or later ...

General information

This application controls the Sun Audio device. By default, the Ptolemy universe that created it configures the device to run stereo at 44.1 kHz with 16-bit linear encoding. This is the simplest (and most useless!) real-time audio demonstration we have -- it just demonstrates that the audio works.

Controls

Input and output selectors
The input and output selectors do the obvious thing. Or, at least, they would if they worked. We haven't gotten around to this yet. Really, buttons would be nicer than check-boxes -- what do you think?
Rec
Controls the gain on the input. For CD source, this should really be down quite low to avoid clipping.
Bal
Controls the balance of the output signal. Negative numbers are left, positive are right (we think...)
Gain
Controls the output gain. Again, if it's too high or there's too much gain in a filter (in other applications), you'll get nasty noises. We really need an amplitude-limiting star to prevent this...
