Stereo Modulator vs True Pan

Stereo Modulator is an AU3 effect that converts mono sound into stereo, with an adjustable width and optional LFO modulation. It works by using a bank of randomized stereo de-correlators that apply micro-delays to introduce random differences between the spectrums of the left and right audio channels. In its output we hear a natural sense of space that is not present in mono recordings. It's similar to the sound space one gets from using a stereo reverb plugin except that it is tight and clear, without echo. It can operate either as a static effect or it can be gently modulated by a low-frequency oscillator. The modulation is akin to the sound of a Leslie speaker, except that it doesn't do any pitch shifting, so the output remains focused and tuning is not compromised. This effect is especially useful for mixing overdriven electric guitar sounds together with vocals. Using Stereo Modulator on the guitars, we can push them out to the sides, creating a space in the centre for the vocal to cut through, without needing to reduce the volume of the guitars. NOTE: Stereo Modulator is an AU3 plugin only, not a standalone app. To use it, you will need an audio unit host app such as Garageband or Audiobus.

True Pan makes it possible to reposition stereo recordings while perfectly preserving the geometry of the stereo field. This allows for lossless, fully reversible panoramic rotations that don't compress the stereo image. The plugin also supports more intense transformations and modulation effects. True Pan can be used to: • Pan sounds that are rich in ambience or reverb without diminishing spatial information • Adjust stereo field recordings, freely rotate the entire sound field (e.g. to change what's in front) • Easily shift sonic perspectives of fx-rich, layered stereo instrument patches • Explore a new dimension of positional reverberation • Add subtle motion to, or "liven up" omnidirectional sounds (can also be used as a special chorus effect at higher rates) • Add a dynamic spatial quality to arpeggiated or rhythmic passages using the tempo sync feature with different LFO types • Apply stronger modulation for sound design and creative uses (creating warble, flutter or stereo tremolo and glitch effects) • Aid and speed up workflows for multi-mic setups When used as a post-processor for reverbs, True Pan can provide higher temporal density and smoothness than what pre-panned reverb inputs would allow. This directly translates to a better quality, but can also be viewed as a different physical setup of the sound source and the listener in relationship to the boundaries of the acoustic space. Thus it opens up additional degrees of freedom in positioning. The plugin's approach to quality preservation is best demonstrated by its ability to transform processed audio back to its original state, by applying a reverse rotation. The included stereo spread controls incorporate features that aim to minimize volume fluctuations by adapting to the actual input signal and its M/S gain distribution, including a fully dynamic adaptive mode, and a snapshot-based one. PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin • Dual mono inputs from two microphones need to be converted to a single stereo signal in order to be processable
