NOTES
Compressor
A compressor essentially works on a signals dynamic range (difference
between audio peaks and lows). Often a compressor is used to reduce the
dynamic range and then allow an increase of the overall signal gain to give
more punch and impact. It can also sound dull if overdone as the nuances
of the dynamics are reduced. Compression techniques can extend further
when layering a compressed sound (to give the impact) with an
uncompressed sound (to give the dynamic subtly). This technique is
sometimes called Parallel or New York Style Compression. In Tracker+ this
can be created with two tracks one with compressed and other
uncompressed then rendering to a single stem or sample.
How does a compressor work?
In basic terms a compressor reduces the level of any audio that exceeds a
threshold. Think of this as an automatic volume control. The amount of gain
reduction is determined by the ratio parameter. A ratio of 1:1 has no gain
reduction while a gentle 2:1 will reduce by 1dB for every 2dB above the
threshold. Higher ratios are more aggressive. The speed and reaction of
the compressor is also governed by an envelope, in Tracker+ this is an
Attack and Release envelope.
