Due to both technical and resource limitations, non-professional audio production must often record with a single microphone, creating a mono audio signal. Even some originally multi-channel audio files often combine the separate channels into a single channel to save memory. However, this channel limitation makes any music held within the audio duller during listening. The Pseudo-Stereo Audio Processor remedies this situation, introducing a quadrature phase shift onto a given single-channel audio signal, producing multiple phase shifted output signals. These separate fixed-phase output signals are then recombined to produce a variable phase difference, emulated two-channel version of the input signal, allowing for an easy post-production sound quality enhancement of a single-channel signal that independent or small-scale audio recording studios could utilize. Further, this method of quadrature filtering produces completely decorrelated output signals using a Hilbert Transform, creating unique auditory effects useful in certain aspects of psychoacoustic research much harder to obtain through other means.
