  • Publication number: 20180238943
    Abstract: A signal processing method generates a time-frequency domain representation of an input signal for the purpose of signal detection, signal display, and application of filtering operations, such as sample accurate spectral editing. The method may include receiving an input signal in the time domain in a processor. The input signal may include a plurality of transform frames. The input signal is transformed into the frequency domain using a frequency transform. Time-frequency matrices are generated from the frequency transform. Crossfrequency phase coupling is applied between adjacent frequency bins to introduce synchronization between adjacent frequencies and to generate smoothed time-frequency matrices with sample-accurate frequency magnitudes. The frequency information can be edited in the time-frequency domain specific to a single sample of the transform frame to alter unwanted signal features.

  • Patent number: 9271080
    Abstract: Methods are disclosed for improving sound localization of the human ear. In some embodiments, the method may include creating virtual movement of a plurality of localized sources by applying a periodic function to one or more location parameters of a head related transfer function (HRTF).

  • Patent number: 9197977
    Abstract: A method and apparatus for processing an audio sound source to create four-dimensional spatialized sound. A virtual sound source may be moved along a path in three-dimensional space over a specified time period to achieve four-dimensional sound localization. A binaural filter for a desired spatial point is applied to the audio waveform to yield a spatialized waveform that, when the spatialized waveform is played from a pair of speakers, the sound appears to emanate from the chosen spatial point instead of the speakers. A binaural filter for a spatial point is simulated by interpolating nearest neighbor binaural filters chosen from a plurality of pre-defined binaural filters. The audio waveform may be processed digitally in overlapping blocks of data using a Short-Time Fourier transform. The localized sound may be further processed for Doppler shift and room simulation.
