soothe2 arrests sibilance, low frequency p-pops (wind) from close-miked singers, bass guitar pops, any peaky electric guitar sounds, and low mid-range frequency buildups encountered in music mixing. The GUI looks like an equalizer except moving a frequency node vertically up and down with the mouse (or by typing a value in), increases/decreases the processing for very specific and problematic frequencies.

soothe2 has both a Soft mode (default) and Hard mode along with a Depth control knob that automatically rescales for either mode. Soft mode is useful for minimally intrusive and more natural sounding control over audio. For more serious problems Hard mode is available.

Using both the Selectivity and Sharpness controls further defines the exact frequency ranges and amount of reduction. You may also hear what you're reducing by clicking on the Delta button.

I liked using soothe2 on problem tracks in my mix when meticulous automation moves still did not sound good to me. The stereo mode works great when there is a problem only on one side, and not the other. Stereo can also unlink and operate in dual mono or a Mid/Side processor as well.

soothe2 proves itself as a professional level processor with features like 2X Oversampling for increased spectral and time resolution, Attack and Release time controls for the reduction process, side-chain abilities, Wet/Dry control, and a Bypass button for quick A/B comparisons that keeps soothe2 in circuit with CPU usage and delay compensation and Wet/Dry mix intact--just without any reduction. All parameters are automatable.

A good read is the manual to make the most efficient use of soothe2. It is the best repair tools you can own and have at the ready. It sells for $219 MSRP download and the upgrade is $59.
