    Abstract: A method and system are provided for acoustic noise removal from human speech, wherein noise is removed without respect to noise type, amplitude, or orientation. The system includes microphones and a voice activity detection (VAD) data stream coupled among a processor. The microphones receive acoustic signals and the VAD produces a signal including a binary one when speech (voiced and unvoiced) is occurring and a binary zero in the absence of speech. The processor includes denoising algorithms that generate transfer functions. The transfer functions include a transfer functions generated in response to a determination that voicing information is absent from the received acoustic signal during a specified time period. The transfer functions also include transfer functions generated in response to a determination that voicing information is present in the acoustic signal during a specified time period. At least one denoised acoustic data stream is generated using the transfer functions.

    Abstract: Methods and systems for efficient synchronous playback among a group of devices using both locally and remotely stored data from one or more content providers are provided. A content identification and matching system can be used to identify local content on the group of devices and match the local content to content available from remotely available libraries. A control and content delivery system can be used to allow multiple devices to synchronously play content from local or remote sources as available.
