Stereo Delay vs Mid

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. ***

Ever wonder what lies between the L/R and M/S representations? Mid-Side Continuum extends the definition of mid-side encoding to create a smooth, continuous interval allowing in-between values and gradual changes. Channel mode switches can now be turned into faders, opening up new modulation possibilities as well. The algorithm used by the plugin is a true extension of the mid-side encoder/decoder concept and doesn't involve any cross-fading or other artificial constructs. The plugin can be used in two ways: • In standalone mode, as a width-preserving panning effect, or a special modulation effect for spatially balanced sounds • In paired mode, allowing other effects to operate anywhere between L/R and M/S modes, with modulation options available FEATURES: • Provides a new kind of spatial modulation effect for stereo signals • Can be used as a panner that doesn't squash wide components (existing ambience, reverb, stereo FX), strongly panning narrow parts at the same time • A great companion for delays or delay-based effects: explore adding space or change the panoramic character without re-configuring delay taps • Turn any stereo effect or effects chain into a M/S one (or any graduation on the L/R - M/S curve), by sandwiching them between a pair of Mid-Side Continuum instances • Unlike panning, stereo panning, or binaural panning, Mid-Side Continuum preserves the exact geometry of the stereo field by using a lossless transform • Higher rates of change can be used to create additional kinds of effects (chorus, warble/flutter), depending on the width characteristics of the original input • A tempo sync capable LFO is available to add automatic modulation; the LFO phase can be offset to allow precise timing control and alignment THE PANNER FOR REVERB-RICH SOUNDS: Panning high-ambience and reverb-rich sounds need no longer result in squashed stereo images. The exact, full width of the stereo field is preserved when using Mid-Side Continuum as a panning tool. Unlike binaural panning, the overall stereo frequency response is kept maximally flat, thanks to the used algorithm's audio engineering-focused feature set. In fact, Mid-Side Continuum's algorithm is a lossless, completely reversible one (based on True Pan's technology). WRAP ANY EFFECT TO CHANGE / MODULATE THEIR STEREO MODE: Two Mid-Side Continuum instances can be conveniently linked in a way that the second one cancels out the transformation, restoring the original sound. Once linked, the second plugin will automatically re-align if parameters are changed in the first one, without missing a single sample. Between these two points, any number of audio effects can be inserted, all of which will receive the transformed signal instead of the original L/R one. This setup can be used in multiple ways: either to just turn any stereo plugin into a M/S one, or to modulate the stereo field of the wet signals (while keeping the dry signal intact) without the need for setting up additional routing, thus keeping tracks neatly self-contained. VERSATILE EXTENSION TO DELAY-BASED EFFECTS: • Alter stereo delay patterns or turn a mono multi-tap delay into a stereo one on the fly • Instead of having to choose from the two, explore any setting between L/R and M/S delay modes to select the best-fitting stereo response • Remove excessive L/R slappiness without losing any stereo width by spatially equalizing the delay output, filling in directions not populated by L/R taps • Improve the clarity of the mid channel / mono mix when combining panned delays with shorter notes or more rhythmic passages • Lessen any "clockwork-like" quality of panned delays that may be experienced with some instruments or passages • Change or fine-tune delay patterns that emerge in the mono mix when using stereo delays PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin
