When off, the maximum amplitude equals the maximum potential amplitude
of the waveform. Output reaches the target value only if the waveform reaches
its maximum potential amplitude.
The maximum potential amplitude for an 8-bit file is 128; for a 16-bit file, it's
32768.
Real Time Control group
Use this group to create interactive animation that's driven by sound captured
from an external audio source, such as a microphone. Use these options only
for interactive presentations. You can't save the real-time sound or save the
animation produced by the controller.
Enable Real Time Device Sets whether sound is captured from an external
audio source. This option is inactive if a sound capture device is not installed
in your system.
When on, any selected audio file is ignored, and the controller uses sound
captured by the selected device.
When off, the controller uses the selected audio file.
Real Time device list Displays all available real-time sound devices installed
in your system. Select the device you want to use for real time sound capture.
Sample group
This group contains controls to filter out background noise, smooth out the
waveform, and control display in Track View.
Threshold Sets the bottom cut-out level as a percentage of total amplitude.
Any amplitude below the threshold drops to 0.0.
Threshold range is from 0.0 to 1.0.
A Threshold of 0.0 has no effect on amplitude output values.
A Threshold of 1.0 drops all amplitude output values to 0.0.
You can use low threshold values to filter out background noise from the
controller.
Oversampling Smoothes the waveform. Multiple samples are averaged to
remove peaks and valleys. Enter a number in the Oversampling field to
calculate the average
Fast Track View Controls the display of oversampling.
When turned on, oversampling is ignored for the Track View display.
