The SA-3 takes the algorithms of the Engineering Emmy Award winning SA-2 Dialog Processor to another level. New features include adding over 1,000 bands of processing, a user programmable Bias Curve, unique Focus, Range, and Density control over spectral processing, side chain support and mid/side processing. Like the SA-2, the SA-3 is great for removing unwanted spectral spikes in dialogue, vocals, and many other kinds of audio inputs. The SA-3 is also able to track and eliminate persistent peaks, at almost any frequency in the audio spectrum.
