The sa 3 Black Friday deal from McDSP is 46% off the SA-3 Spectral Processor, bringing it to $69 until Nov 23, 2026.
The SA-3 Spectral Processor is a spectral analysis plugin for pulling unwanted spikes out of dialog, vocals and many other kinds of audio. It builds on the algorithms of the SA-2 Dialog Processor, which won an Engineering Emmy Award.
Its core job is catching spectral spikes and cleaning them up.
The maker says it can also track and remove persistent peaks at nearly any frequency in the audio spectrum.
That covers two different problems: short-lived spikes in a voice, and overtones that hang around for the whole take.
McDSP lists several additions over the SA-2: more than 1,000 processing bands, a bias curve you can program yourself, side chain support and mid/side processing, plus Focus, Range and Density controls that shape the spectral processing, which the maker calls unique to this processor. The full list also covers double precision processing, mono and stereo versions, and Detect and Monitor controls for locating signal spikes and lingering overtones so they can be pulled out of the signal.
Double precision processing keeps the maths at 64-bit inside the plugin, which matters when you stack several processors on one bus.
On Mac, you need macOS 10.13 or higher, 64-bit only. macOS 12 Monterey is compatible. McDSP says its plugins run natively on both Intel and M1 Apple Silicon processors.
On Windows, you need Windows 10 or later.
McDSP plugins authorise through an iLok2 or iLok3 USB Smart Key, or through a free iLok License Manager account with an iLok Cloud session. Each McDSP v7 plugin includes two activations per authorisation.
Mac OS 10.12.x (Sierra) may work but is not officially supported, and earlier Mac OS versions are not supported at all.
Yes. The SA-3 Spectral Processor carries a Black Friday deal of 46% off, which brings it to $69. The deal ends Nov 23, 2026. It is the McDSP spectral processor for removing spikes and persistent peaks from dialog, vocals and other audio.
The maker says it removes unwanted spectral spikes in dialog, vocals and many other audio inputs. It can also track and eliminate persistent peaks at nearly any frequency. Detect and Monitor controls help you identify those spikes and overtones.
McDSP lists over 1,000 bands of processing, a user programmable Bias curve, Focus, Range and Density controls, side chain support and mid/side processing. The SA-3 builds on the algorithms of the Emmy Award winning SA-2.
On Mac you need macOS 10.13 or higher, 64-bit, running natively on Intel and M1 Apple Silicon. On Windows you need Windows 10 or later. Activation uses an iLok2 or iLok3 key, or a free iLok License Manager account with iLok Cloud.
