Threshold
The [
THRESHOLD]
knob sets the level where compression will begin. As long as the
input signal level is below the Threshold level, the NanoCompressor will do nothing
to the signal. Once the input signal crosses the Threshold, the NanoCompressor will
begin compressing at a ratio set by the [
RATIO]
control.
In the diagram above, Figure (a.) shows the input signal to the NanoCompressor. In
this example the compressor Threshold is set for -10dB and the Ratio is set for 4:1.
When the third peak of the input signal crosses the Threshold, the NanoCompressor
starts to reduce the signal level, as shown in Figure (b.). Figure (c.) shows the output
signal level, with the original signal shown with a dotted line.
