Abstract
A processing method includes acquiring an audio signal, magnifying one or more first portions of the audio signal in response to one or more magnitudes of the one or more first portions of the audio signal are lower than a predetermined threshold, deforming one or more second portions of the audio signal in response to one or more magnitudes of the one or more second portions of the audio signal are greater than the predetermined threshold, and performing a noise reduction to the one or more deformed second portions of the audio signal to reduce the one or more deformed second portions of the audio signal.
Claims17
An audio signal processing method, comprising:
- acquiring an audio signal;
- magnifying one or more first portions of the audio signal in response to one or more magnitudes of the one or more first portions of the audio signal are lower than a predetermined threshold;
- performing a modulo operation to one or more second portions of the audio signal in response to one or more magnitudes of the one or more second portions of the audio signal are greater than the predetermined threshold;
- and
- performing a noise reduction to the one or more second portions of the audio signal obtained by performing the modulo operation to reduce the one or more second portions of the audio signal obtained by performing the modulo operation.
An audio signal processing electronic device, comprising:
- one or more processing components;
- a memory electrically connected to the one or more processing components;
- and
- one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processing components, the one or more programs comprising instructions for:
- acquiring an audio signal;
- magnifying one or more first portions of the audio signal in response to one or more magnitudes of the one or more first portions of the audio signal are lower than a predetermined threshold;
- performing a modulo operation to one or more second portions of the audio signal in response to one or more magnitudes of the one or more second portions of the audio signal are greater than the predetermined threshold;
- and
- performing a noise reduction to the one or more second portions of the audio signal obtained by performing the modulo operation to reduce the one or more second portions of the audio signal obtained by performing the modulo operation.
A non-transitory computer readable storage medium storing one or more programs comprising instructions, which when executed, causes one or more processing components to perform operations comprising:
- acquiring an audio signal;
- magnifying one or more first portions of the audio signal in response to one or more magnitudes of the one or more first portions of the audio signal are lower than a predetermined threshold;
- performing a modulo operation to one or more second portions of the audio signal in response to one or more magnitudes of the one or more second portions of the audio signal are greater than the predetermined threshold;
- and
- performing a noise reduction to the one or more second portions of the audio signal obtained by performing the modulo operation to reduce the one or more second portions of the audio signal obtained by performing the modulo operation.
