Pi & Phi use these harmonious magic numbers to introduce an innovative way of spectral processing. They create an acoustic effect that can be described as “super-enhanced” with a warm yet powerful “sparkle” to it.

Pi & Phi MkIII features 10 bands that cover the frequencies from 80 Hz up to 16KHz, along with a “Super Low” and a “Super High” band to cover the extremes of the spectrum. 

This great sound enriching tool benefits from separate components that have minimum phase distortion. This enables the user to precisely shape the spectral balance based on the Golden Ratio.

The Pi & Phi plug-in also stands out from the crowd with its “demasking” capabilities. It is very well suited in making an instrument or vocal track ‘cut-through’ and stand-out from the rest, especially in a cluttered mix.

Overall this is a very effective yet easy-to-use tool. It is as well very ‘forgiving’, since the amount of distortion introduced is minimal compared to the increase in “loudness” perceived, even when using extreme settings.

In this latest version, Pi & Phi use the signal processing path of the 358 Enhancer, it delivers the round and solid low-end that it is well known for. The updated GUI also incorporates an Input/Output spectrum analyser, while the controls are placed in a way that corresponds to the frequency bands displayed on top of them.
