Untrained Blind Sound Source Separation
by Unsupervised Synchrony Loop Network

A newly instantiated, completely untrained Synchrony Loop Network listens to this (single audio channel) musical duet.

Musical Duet
Input

The network learns each instrument's sound profile in real time without supervision. Within 1 second of audio onset, it can simultaneously track and precisely extract each instrument.

The separated audio outputs are below.

Another newly instantiated, completely untrained Synchrony Loop Network listens to a saxophone in a crowded auditory scene.

Saxophone in Noise
Input

Within 0.1 seconds of audio onset, the network identifies the saxophone as a distinct sound source within the scene and begins to follow and extract it.

Within 1 second it learns its sound profile precisely enough to separate the saxophone from all other sounds.
