Patent number: 8812322Abstract: Systems and methods for semi-supervised source separation using non-negative techniques are described. In some embodiments, various techniques disclosed herein may enable the separation of signals present within a mixture, where one or more of the signals may be emitted by one or more different sources. In audio-related applications, for instance, a signal mixture may include speech (e.g., from a human speaker) and noise (e.g., background noise). In some cases, speech may be separated from noise using a speech model developed from training data. A noise model may be created, for example, during the separation process (e.g., “on-the-fly”) and in the absence of corresponding training data.Type: GrantFiled: May 27, 2011Date of Patent: August 19, 2014Assignee: Adobe Systems IncorporatedInventors: Gautham J.

Publication number: 20140201630Abstract: Sound decomposition techniques and user interfaces are described. In one or more implementations, one or more inputs are received via interaction with a representation of sound data in a user interface, the one or more inputs indicating a portion and corresponding intensity of the sound data.
