Publication number: 20210256971Abstract: A method of detecting a replay attack comprises: receiving an audio signal representing speech; identifying speech content present in at least a portion of the audio signal; obtaining information about a frequency spectrum of each portion of the audio signal for which speech content is identified; and, for each portion of the audio signal for which speech content is identified: retrieving information about an expected frequency spectrum of the audio signal; comparing the frequency spectrum of portions of the audio signal for which speech content is identified with the respective expected frequency spectrum; and determining that the audio signal may result from a replay attack if a measure of a difference between the frequency spectrum of the portions of the audio signal for which speech content is identified and the respective expected frequency spectrum exceeds a threshold level.Type: ApplicationFiled: July 31, 2019Publication date: August 19, 2021Applicant: Cirrus Logic International Semiconductor Ltd.Inventors: John Paul LESSO, César ALONSO, Earl Corban VICKERS

Patent number: 9673770Abstract: A multiband dynamics compressor implements a solution for minimizing unwanted changes to the long-term frequency response. The solution essentially proposes undoing the multiband compression in a controlled manner using much slower smoothing times. In this regard, the compensation provided acts more like an equalizer than a compressor. What is applied is a very slowly time-varying, frequency-dependent post-gain (make-up gain) that attempts to restore the smoothed long-term level of each compressor band.Type: GrantFiled: November 12, 2015Date of Patent: June 6, 2017Assignee: STMICROELECTRONICS, INC.Inventor: Earl Corban Vickers

Patent number: 9413316Abstract: Psychoacoustic bass audio signal enhancement can be accomplished using a monotonic, asymmetric polynomial distortion. A non-linear process applies a monotonic, asymmetric polynomial distortion function that has continuous first and second derivatives to generate even and odd harmonics of missing fundamental frequencies. This polynomial distortion produces the desired psychoacoustic effect with a fairly rapid rolloff so as to avoid unpleasant aliasing. Moreover, the lack of first-order discontinuities prevents clicks or glitches.Type: GrantFiled: December 16, 2013Date of Patent: August 9, 2016Assignee: STMicroelectronics, Inc.Inventor: Earl Corban Vickers

Publication number: 20130332498Abstract: Embodiments are directed to efficient frequency-domain implementations of time-varying FIR filters. More specifically, time-varying FIR filters according to embodiments exploit the duality of the fast Fourier transform that windowing in the time domain equals convolution in the frequency domain. In one embodiment, convolution of the output of the FIR filter and a desired windowing function is performed in the frequency domain instead of taking the output of the FIR filter in the frequency domain, converting this output the time domain via an IFFT, and then windowing this output in the time domain before again converting back to the frequency domain. As long as the windowing function has certain characteristics, then the time-varying FIR filter is computationally efficient and introduces minimal audible artifacts into the output of the filter. Concepts described herein are discussed in terms of audio signals and systems but are not limited to audio signals and systems.Type: ApplicationFiled: May 20, 2013Publication date: December 12, 2013Applicant: STMICROELECTRONICS, INC.Inventor: Earl Corban VICKERS

Publication number: 20080085008Abstract: A method and device for creating late reverberation in the frequency domain using spectral magnitude decay. The method applies a frequency domain representation of an input signal to a frequency domain accumulator having a delay, an adder and a frequency-dependent magnitude attenuation. The attenuated magnitude is combined with an artificial phase signal to produce one or more output signals. The method enables detailed control of late reverberation decay times as a function of frequency.Type: ApplicationFiled: September 29, 2007Publication date: April 10, 2008Inventor: Earl Corban Vickers
