摘要： An audio equivalent of a video zoom feature for video recording and communication applications, as well as video post production processes. The audio zoom may operate in conjunction with a video zoom feature or independently. The audio zoom may be achieved by controlling reverberation effects of a signal, controlling a gain of the signal, as well as controlling the width of a directional beam from which is used to select the particular audio component to focus on. The audio zoom may operate in response to user input, such as a user selection of a particular direction, or automatically based on a current environment or other factors.

摘要： The present technology provides a robust noise suppression system which may concurrently reduce noise and echo components in an acoustic signal while limiting the level of speech distortion. An acoustic signal may be received and transformed to cochlear domain sub-band signals. Features such as pitch may be identified and tracked within the sub-band signals. Initial speech and noise models may be then be estimated at least in part from a probability analysis based on the tracked pitch sources. Speech and noise models may be resolved from the initial speech and noise models and noise reduction may be performed on the sub-band signals and an acoustic signal may be reconstructed from the noise-reduced sub-band signals.

摘要： A robust noise reduction system may concurrently reduce noise and echo components in an acoustic signal while limiting the level of speech distortion. The system may receive acoustic signals from two or more microphones in a close-talk, hand-held or other configuration. The received acoustic signals are transformed to cochlea domain sub-band signals and echo and noise components may be subtracted from the sub-band signals. Features in the acoustic sub-band signals are identified and used to generate a multiplicative mask. The multiplicative mask is applied to the noise subtracted sub-band signals and the sub-band signals are reconstructed in the time domain.

摘要： Systems and methods for reconstructing decomposed audio signals are presented. In exemplary embodiments, a decomposed audio signal is received. The decomposed audio signal may include a plurality of sub-band signals having successively shifted group delays as a function of frequency from a filter bank. The plurality of sub-band signals may then be grouped into two or more groups. A delay function may be applied to at least one of the two or more groups. Subsequently, the groups may be combined to reconstruct the audio signal, which may be outputted accordingly.

摘要： Systems and methods for noise suppression using noise subtraction processing are provided. The noise subtraction processing comprises receiving at least a primary and a secondary acoustic signal. A desired signal component may be calculated and subtracted from the secondary acoustic signal to obtaining a noise component signal. A determination may be made of a reference energy ratio and a prediction energy ratio. A determination may be made as to whether to adjust the noise component signal based partially on the reference energy ratio and partially on the prediction energy ratio. The noise component signal may be adjusted or frozen based on the determination. The noise component signal may then be removed from the primary acoustic signal to generate a noise subtracted signal which may be outputted.

摘要： Systems and methods for a dynamic audio perspective change during video playback are provided. A pre-recorded video is played with an associated raw audio signal. The audio signal is modified in real time based on an audio processing mode. The audio processing mode can be selected during the video playback via a graphic user interface. By selecting the audio processing mode, a user can attenuate one or more components of the pre-recorded raw audio signal. The components include near source sounds, distant source sounds, and a noise. After the desired audio processing mode is selected the entire audio signal is reprocessed according to the selected mode in a background process and stored in a memory.

摘要： Systems and methods for providing karaoke recording and playback on mobile devices are provided. The mobile device may play music audio and associated video, and receive via one or more microphones a mix of a user voice, the music, and background noise. The mix is stored both in its original form and as processed to enhance voice and sound through noise suppression and other processing. Stored audio may be uploaded through a communications network to a cloud based computing environment for listening on other mobile devices. Selectable playing control and recording options may be provided. Audio cues may be determined during signal processing of the original acoustic sound and be stored on the mobile device. During playback of recorded audio and, optionally, associated video, the original acoustic sound, recorded cues, and user selectable optional processing may be used to remix during playback, while retaining the original recording.
