Sound Card Band-Limited Noise Dialog

Controls: Gen Dlg >> Stream >> Wave >> Band
Macro: Wave=Band

This allows you to create either a band of noise, or wideband noise with a gap. You can control the rising and falling band edge frequencies, steepness, and shape using the Band dialog:

Macro Notes:

L.1.Wave=Band or L.1.Wave=10 sets Left Stream 1 Wave to Band. Note that this command format sets Wave but does not open the Band dialog. This is the usual approach for modifying Generator setups.

To set Wave to Band and also open the Band dialog (if the Wave dialog is already open), use a D. prefix as in D.L.1.Wave=Band.
