What Is A Multiband Compressor?
The multiband compressor is all the
rage in mastering these days, causing main software manufacturers to include
this function in their mastering packages. Be it Waves, SoundForge, WaveLab, or
Izotope's Ozone Suite, you'll find this this powerful, but tricky tool available
In effect, the
multiband compressor splits the audio into separate signals, similar to a
crossover network in a speaker system, and then provides separate compression
for each of these split signals. Each "band" only contains energy in a
particular frequency band. Finally it will recombine the separate signals/bands
back into one signal. If you had three bands in your unit, the equivalent
patching of hardware to achieve this is shown in figure 1.
