Stereo Delay vs True Pan

Blue Mangoo Stereo Delay is designed to be the go-to app a for simple, musically tasteful delay effect. The most unique feature is the way it handles panning of delayed echoes in the stereo field. Most stereo delays set different delay times for the left and right channels, resulting in the famous ping-pong effect. The problem with the ping-pong stereo delay sound is that it's too extreme, and our ears quickly tire of hearing the same pattern of left-then-right delay repeated hundreds of times. This plugin does it differently. Instead of setting delay taps at different times panned hard left or right, it always keeps the same delay time setting for both the left and right channels, but it has a unique mixing matrix controlling the feedback between the left and right channels so that each time the echo repeats, it appears in a new place in the stereo field. This is different from a simple panning delay, because older echoes and newer ones can simultaneously appear at different positions in the stereo field. The result is a very natural stereo echo that expands the stereo width of the sound but doesn't sound repetitive or electronic. It's constantly moving and changing. The wet signal output has low-cut and hi-cut filters. The hi-cut filter tones down the harshness of the delay and makes it sound like natural echoes. The low-cut is especially useful for applying delay without making things sound muddy. At extreme settings the low cut can achieve a lo-fi telephone like delay sound. The signal flow diagram is as follows: Filters => LFO controlled pan => Stereo Delay Lines => Mixing matrix => Feedback to Delay Lines The dry signal (not shown above) bypasses the entire effect. The key difference between this and other delays is the mixing matrix, which is similar to the ones used in feedback delay network reverb effects to mix between multi-channel delays without changing the volume of the sound. It is the matrix (not the LFO) that creates the illusion that the signal has moved to a different location in the stereo field each time it repeats through the delays. *** THIS IS AN AUDIO UNIT ONLY EFFECT. IT REQUIRES A HOST APP SUCH AS AUM, Audiobus, GarageBand, OR Cubasis. IT DOES NOT RUN AS A STANDALONE APP. ***

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
