[sdiy] Taking a Step towards Digital Synthesis?....

[Jay Schwichtenberg]

I know that the early Sony recorders that recorded on video tape (at that
time it was Beta) used something like 44.05 kHz. It was because that worked
well to pack audio into a video frame.

I think that 48 kHz is used in broadcast now days.
