Sound Card Wave Dialog - Generator Stream

Controls: Generator Dialog >> Stream >> Wave
Macro: WaveDlg

This button opens a dialog that allows you to select the type of waveform generated by the Stream. Below it is a status indicator that shows the current selection. The default is 'Sine'.

The Wave dialog options are in three groups: Those at the top are regular waveforms including Sine, Triangle, Ramp, Square, and Pulse. Below those are Arb and Play, for waveforms that are loaded as separate files. At the bottom are random Noise options, including White, Gauss, Pink, and Band.

Clicking on a Wave dialog button selects that waveform type. For Ramp, Pulse, Arb, Play, Gauss, and Band types this action also opens a special dialog with additional controls that are specific to the wave type.

Macro Notes:

WaveDlg=1 opens the Wave dialog if the Stream dialog is open, WaveDlg=0 closes it, and WaveDlg=x toggles between open and closed.

Note that you do not need to open this dialog to change controls directly via macro command.

Use channel and stream prefixes with the Wave macro to set the Wave type, such as L.0.Wave=Sine to set Left Stream 0.

You can set Wave types by name, as in L.1.Wave=Tri, or you can use numeric values, variables, or expressions for setting, reading, or IF testing. For example, L.1.Wave=A + B would set Pink if A + B equals 9.

    0 = Sine
    1 = Tri
    2 = Ramp
    3 = Square
    4 = Pulse
    5 = Arb
    6 = Play
    7 = White
    8 = Gauss
    9 = Pink
    10 = Band

Note that if you use a mnemonic in an IF test, it must be in quotes: IF.Wave="Tri".
