Improve the summing of your favorite Digital Audio Workstation

Sound Radix PI is an innovative, multi-channel phase interactions mixer plug-in engine for Mac and PC.

Good phase relationships are key to a great-sounding mix. When tracks are summed into a stereo mix bus, instruments tend to overlap and interact with each other across the frequency range and phase position. A bass track could be temporarily out of phase with the kick or rhythm guitar tracks, and when summed together the two instruments would cancel each other out over the overlapping frequency range, causing a temporary “hole” in the low end. Similarly, a snare track could end up sounding thin in a mix when the toms’ resonance is out of phase with the snare.

Why PI?

PI works to improve the summing of your favorite Digital Audio Workstation. PI minimizes overlapping frequency cancellations between instruments within the mix, improves mono compatibility, and brings back the depth and focus lost when out-of-phase frequencies in the mix cancel each other out.

Dynamic Phase Rotation

Instruments with similar frequency content, such as bass and bass-drum, can be temporarily out of phase and cancel each other’s fundamental frequencies. The resulting sound is often described as “thin” and “hollow”. Because those interactions happen randomly across varying frequencies and to different degrees, this effect cannot be remedied using a simple, fixed phase-rotator or equalizer.

PI constantly analyzes the phase correlation of each track and dynamically adjusts their respective phases to achieve optimal correlation and maintain the full depth and timbre of the instruments in the arrangement.

True Multi-Track Awareness

PI utilizes a unique central background processor to sample-accurately analyze and process the phase position of each track to achieve the optimal phase relationships in your mix in real-time.

Multi-band Phase Correlation Meter

PI’s multi-band Phase Correlation Meter displays the phase correlation of each frequency band as well as overall phase correlation.

Groups & Global Operation Modes

Use any of the 64 groups to bind multi-microphones recording or related instruments to further optimize their phase relationships in the mix.

Two operation modes enable Full Range phase optimization or focus on the Low-Frequency range of your mix.
