摘要： A system and method are provided for processing sound signals. The processing may include identifying individual harmonic sounds represented in sound signals, determining sound parameters of harmonic sounds, classifying harmonic sounds according to source, and/or other processing. The processing may include transforming the sound signals (or portions thereof) into a space which expresses a transform coefficient as a function of frequency and chirp rate. This may facilitate leveraging of the fact that the individual harmonics of a single harmonic sound may have a common pitch velocity (which is related to the chirp rate) across all of its harmonics in order to distinguish an the harmonic sound from other sounds (harmonic and/or non-harmonic) and/or noise.

摘要： To provide a bandwidth extension method which allows reduction of computation amount in bandwidth extension and suppression of deterioration of quality in the bandwidth to be extended. In the bandwidth extension method: a low frequency bandwidth signal is transformed into a QMF domain to generate a first low frequency QMF spectrum (S11); pitch-shifted signals are generated by applying different shifting factors on the low frequency bandwidth signal (S12); a high frequency QMF spectrum is generated by time-stretching the pitch-shifted signals in the QMF domain (S13); the high frequency QMF spectrum is modified (S14); and the modified high frequency QMF spectrum is combined with the first low frequency QMF spectrum (S15).

摘要： A user interface using an acoustic signal is provided. A device with the user interface includes a sensor to acquire a surface acoustic signal generated outside of the device, and at least one processor. The processor classifies patterns of the surface acoustic signal by analyzing features of the surface acoustic signal, and identifies a user's input signal corresponding to the surface acoustic signal based on the pattern of the surface acoustic signal.

摘要： In one alternative, an audio signal is analyzed using multiple psychoacoustic criteria to identify a region of the signal in which time scaling and/or pitch shifting processing would be inaudible or minimally audible, and the signal is time scaled and/or pitch shifted within that region. In another alternative, the signal is divided into auditory events, and the signal is time scaled and/or pitch shifted within an auditory event. In a further alternative, the signal is divided into auditory events, and the auditory events are analyzed using a psychoacoustic criterion to identify those auditory events in which the time scaling and/or pitch shifting processing of the signal would be inaudible or minimally audible. Further alternatives provide for multiple channels of audio.

摘要： The present invention provides a sound processing apparatus, a sound processing method and a hearing aid for efficiently emphasizing the sound of an utterer close to the user regardless of the distance between microphones. By using output signals from a plurality of omnidirectional microphones, respectively, the sound processing apparatus outputs a first directivity signal in which the main axis of directivity is formed in the direction of the utterer and outputs a second directivity signal in which the dead zone of directivity is formed in the direction of the utterer. The sound processing apparatus calculates the level of the first directivity signal and the level of the second directivity signal, and determines the distance to the utterer based on the level of the first directivity signal and the level of the second directivity signal. The sound processing apparatus derives a gain to be given to the first directivity signal according to the result of the determination and controls the level of the first directivity signal by using the gain.
