M/S Processor is an Audiobus-compatible iOS application intended for audio professionals requiring Mid/Side (M/S) signal processing.
While the most common use case for M/S Processor is decoding a M/S signal to L/R, the reverse process (encoding L/R to M/S) is also possible. A third mode, inline mode, is also included. In this mode, a stereo signal is encoded to M/S, and then decoded again to L/R. This 2-in-1 mode is useful for tasks such as narrowing or widening the stereo image, or muting the M or S channels independently for creative or experimental purposes.
M/S Processor is most useful when used as an Audiobus filter. In this case, M/S Processor can be used to process audio before feeding it into any other Audiobus-compatible audio application such as Apple's Garageband for recording and further processing.
