Frequency Sweep Length


Macro: SweepLength

Sets the duration of the frequency sweep in either samples or seconds, depending on the Samples/Seconds button. The maximum sweep length is limited by the 32-bit size of the length variable, in samples: Over 4 billion samples, or roughly 24 hours at 48000 samples per second.


Macro Notes:

L.1.SweepLength=10 directly sets the Left Stream 1 Sweep Length to 10 seconds, assuming sec mode. Note that this will set 10 samples in Smpl mode. To be safe, use a SmplSec command to set the desired mode before using this command.

L.1.SweepLength>1 increments and L.1.SweepLength=>-1 decrements by one sample, even in sec mode. Only +/-1 sample steps are allowed.
