PCM is like ordinary .wav data. Berni: "This is actually how MIDI works, playing samples at different speeds" - Truly incredible! MIDI doesn't do any sound. Good luck in the future! :-) Thanks for the interesting sound examples and comparisons! :-)

Not true at all. PCM is like ordinary .wav data.

Berni: “This is actually how MIDI works, playing samples at different speeds” -
Truly incredible! MIDI doesn’t do any sound.

Given enough clock speed it should be simple enough. Have you considered using PWM on each line of the 4 bit R2R DAC to extend it’s resolution? Given enough clock speed it should be simple enough.

Anyway for those that want a good software for MIDI and audio check this http://reaper.fm/feat-ss.php Very nicely made piece of software that has a free trial of 30 days but is still functional afterwards it just displays a "buy me" message I had some problems with MIDI input, only MIDI output worked.

Berni,

Should be an additional 0 there, right? I believe there’s a typo in “Consider that decimal 128 is 1000000 in binary.”. Should be an additional 0 there, right?

One of the ideas I've had for using sound is to use it to provide a non-visual user interface by way of sampled speech. I've got a "spy pen camera" that uses such an interface--I blogged about it http://words.rancidbacon.com/sneaky-spy-camera-pen-2007-02-28-03-45.html and the post includes a link to the (rather poor) sound. The principle advantage is the ability to have an interface that doesn't require the space a LCD would take up. Plus it's just kinda cool. :-) --Phil.
