I don't think we agree on, well, much of anything! But I wanted to send you this observation on the audio monitor...
(stereo pokey enabled, so Phaeron already knows just to concentrate on the left side)
This is the beep from a sector loading from disk.
Just about anyone (not knowing the special notations) would look at it and say, "Oh! We've got audio on the 4th channel."
So, a disk access about that time might have looked something like this:
AUDF1: 00 AUDC1: a8 Output: 0
AUDF2: 00 AUDC2: a8 Output: 0
AUDF3: 28 AUDC3: a8 Output: 1
AUDF4: 00 AUDC4: a8 Output: 0
AUDCTL: 28, 17-bit poly, 1.79 ch3, ch3+ch4, 64KHz
After digging into it a bit, a person might observe, "Oh. That isn't the 4th channel making sound. Channels 3 and 4 are tied into a single channel and making that sound. Okay."
Going back to the audio monitor graph, you actually have noted that channels 3 and 4 are combined with a "16" to the left on channel 4. But if I have to wonder if there might be a more intuitive way of representing two channels tied together to produce a single frequency. Something where an average person would see it and immediately say, "Oh! These are a combined channel!"
That's all I got. Thanks!
PS: I've figured out 64K, 1.79, and T (tone mode), but the 5/L notation was a little confusing at first. It took experimentation for me to realize that "L" would represent the highest bit of AUDC being set for a channel. Does it stand for Linear? Level? Volume-only mode was obvious, though. Insert disclaimer about this actually being a communications timer that we happen to be allowed to hear.
