About

Mid

This app offers unique stereo transformations, allowing for smooth, continuous intervals between L/R and M/S representations. It enables new modulation possibilities and can be used as a width-preserving panner or to transform any stereo effect into an M/S one.

Highlights
  • Continuous mid-side interval
  • Width-preserving panning
  • Spatial modulation effect
  • Transform stereo effects to M/S
  • Lossless stereo field preservation
  • Tempo sync capable LFO
  • Paired mode for effect modulation

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

Verdict

The call

The clearest difference is price: SFX Library Lite at Free against Mid's $5.99. SFX Library Lite also leads on update cadence (every 5 weeks vs every 14 months). Mid's advantage is ads (none vs shown) and ratings volume (6 vs 2). On rating, in-app purchases and device support there is nothing between them.
