Recording, Mixing and Mastering of Audio Using a Single Microphone Array and Audio Source Separation Algorithms

The authors present a new way of recording of music bands using a single microphone array and audio source separation algorithms. In contrast to the traditional recording process, this novel approach allows for capturing all of musical instruments simultaneously using only one recording device, avoiding a multiple sets of spot microphones, cables, and D/A converters. Moreover, using a single microphone array and dedicated algorithms gives the sound engineer a unique set of “audio processing tools” that can be used in the post-production stage. This paper describes step-by-step a recording process of a music band playing ukulele using a 19-capsules spherical microphone array and dedicated software. The process includes the following stages: recording, sound source separation, mixing, and mastering.
