Multichannel sound source identification and location techniques are described. In one or more implementations, source separation is performed using a collaborative technique for a plurality of sound data that was captured by respective ones of a plurality of sound capture devices of an audio scene. The source separation is performed by recognizing spectral and temporal aspects from the plurality of sound data and sharing the recognized spectral and temporal aspects, one with another, to identify one or more sound sources in the audio scene. A relative position of the identified one or more sounds sources to the plurality of sound capture devices is determined based on the source separation.
