4results about How to "Improve audio quality" patented technology

This invention provides an audio dynamic range control circuit and an audio device. The audio dynamic range control circuit includes an audio zero-crossing detection circuit, a preprocessing circuit, a first control circuit, a first gain selection circuit, a gain multiplication processing circuit, a second control circuit, a third control circuit, and a second gain selection circuit. The audio dynamic range control circuit provided by this invention achieves an effect similar to the existing RMS algorithm by performing absolute value processing on the linear domain sampling data of the audio signal, while simplifying the hardware circuit implementation. Simultaneously, by detecting the zero-crossing position of the audio signal through the audio zero-crossing detection circuit, and updating the gain value at subsequent zero-crossing positions when a sampling point with high energy is detected, the nonlinearity of the output signal can be greatly improved and auditory discomfort can be eliminated, effectively improving audio quality.

Embodiments of the present application provide an audio data processing method, a server and a program product. The method is applied to a server, and the method comprises: performing redundant coding processing on to-be-processed audio data to obtain coded audio data, in a case where it is determined based on network state information that the redundant coding process is to be performed; and performing a first redundancy processing operation on the coded audio data to obtain processed audio data. The method significantly improves the quality of audio transmission in a weak network environment, reduces audio delay, freezing and distortion, and improves user experience.

The present disclosure relates to an audio recording method, device, electronic equipment, storage medium and program product. The audio recording method comprises: determining at least one target channel satisfying a preset condition during audio recording, the preset condition representing that the audio quality of the audio data obtained by recording through the target channel is higher than a preset audio quality; and recording audio through the at least one target channel to obtain target audio data. The method uses the target channel with audio quality higher than the preset audio quality to record and obtain target audio data, which can obtain high-quality input speech, improve the audio quality of the input speech, especially in the speech-to-text input scene, which can effectively improve the accuracy of speech-to-text, and thus improve the user experience of the speech input function.
