摘要： Example techniques involve calibration of one or more playback devices. An example implementation involves a playback device playing back audio content using a first calibration via the one or more audio transducers and the one or more amplifiers. The first calibration is based on a response of a listening environment to audio content playback by the playback device. The playback device records, via one or more microphones, at least a portion of the played back audio content. Based on the recorded audio content, the playback device detects a change in the response of the listening environment to audio content playback by the playback device. Responsive to detecting the change in the response, the playback device causes output of a prompt to initiate a calibration procedure for the playback device. The calibration procedure involves a mobile device recording playback by the playback device.

摘要： At least one exemplary embodiment is directed to a method and device for voice operated control with learning. The method can include measuring a first sound received from a first microphone, measuring a second sound received from a second microphone, detecting a spoken voice based on an analysis of measurements taken at the first and second microphone, learning from the analysis when the user is speaking and a speaking level in noisy environments, training a decision unit from the learning to be robust to a detection of the spoken voice in the noisy environments, mixing the first sound and the second sound to produce a mixed signal, and controlling the production of the mixed signal based on the learning of one or more aspects of the spoken voice and ambient sounds in the noisy environments.

摘要： A device, system, and a method for adjusting audio parameters for a user are disclosed. The method comprises performing a hearing test of the user. The hearing test comprises playing an audio and capturing an auditory response of the user towards the audio. A hearing profile of the user is generated based on one or more results of the hearing test. A playing speed of the audio is adjusted based on the hearing profile, thereby adjusting the audio parameters for the user.

摘要： A digital microphone includes a log amplifier having an input for receiving an analog signal; an analog-to-digital converter (ADC) coupled to the log amplifier; a digital low-pass filter coupled to the ADC; a digital decompression component coupled to the digital low-pass filter; and a predictor filter coupled to the digital decompression component, the predictor filter having an output for generating a digital signal. The digital low-pass filter is a positive group delay filter and the predictor filter is a negative group delay filter. The digital microphone has an improved Signal-to-Noise Ratio (SNR) due to filtering, but without increasing overall group delay.

摘要： In some embodiments, a method for processing an audio signal in an audio processing apparatus is disclosed. The method includes receiving an audio signal and a parameter, the parameter indicating a location of an auditory event boundary. An audio portion between consecutive auditory event boundaries constitutes an auditory event. The method further includes applying a modification to the audio signal based in part on an occurrence of the auditory event. The parameter may be generated by monitoring a characteristic of the audio signal and identifying a change in the characteristic.

摘要： Provided is a preamplifying circuit, including a first amplifier and a second amplifier sequentially connected in series, wherein an output end of the second amplifier is connected to a circuit output end, and an input end of the first amplifier is connected to a circuit input end. The preamplifying circuit further includes a positive feedback branch including a diode group and a third amplifier, wherein one end of the diode group is connected to the input end of the first amplifier. The positive feedback circuit can positively feed part of signals back to the other end of the diode group, so that voltage drops at two ends of the diode group can be reduced, and harmonic distortion caused by nonlinearity of the diode group is reduced. Thus, the sound quality detected by a microphone sensor is improved.
