Get to know them!

McDSP’s SA-2 Dialog Processor is a legendary plug-in among post-production specialists. Now, with the McDSP SA-3 Spectral Processing plug-in, the response has been overwhelmingly positive. With over 1,000 bands of processing, support for sidechain and mid-side processing, unique controls for Focus, Range, Density, and a user-programmable Bias Curve, the SA-3 Spectral Processor plug-in has everything you’ll need for precise dynamics control of any audio signal. Sweetwater recording and post-production engineers find the SA-3 fantastic for taming spikes and annoying overtones in dialogue and vocals anywhere along the audio spectrum, and it features excellent visual feedback for monitoring output, gain reduction, and removed signals. Altogether, the McDSP SA-3 Spectral Processor takes consistent leveling to the next level!

Seek and destroy

SA-3’s Detect control enables an intelligent algorithm to apply over 1,000 processing bands that identify and attenuate unwanted signals and spikes. Simply press the Monitor button to listen to what’s being removed and see what’s being removed in the main LCD window. SA-3 also retains a Bias control that emphasizes or de-emphasizes your selected processing, with adjustments made via its Scale and Shift controls. Finally, the stereo version of SA-3 supports mid-side processing for getting rid of unwanted spikes and resonant frequencies from your mid and side channels.

McDSP SA-3 Spectral Processor Native v7 Plug-in Features:

  • Intelligent spectral dynamics that are pristine for consistent leveling across dialogue, vocals, and other sound sources
  • 1,000+ bands of spectral processing
  • Detect and Monitor controls intelligently identify and attenuate or even completely remove spikes and noisome overtones
  • User-programmable Bias Curve with controls for Shape and Shift to fine-tune your desired processing
  • Unique controls for Focus, Range, and Density
  • Sidechain support
  • Mono and stereo versions, with M-S processing supported in the stereo version

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
