Noise reduction method and device

An electronic device, comprising:

• a memory, configured to store program instructions for performing a noise reduction method;
• and
• a processor, coupled with the memory and, when executing the program instructions, configured to:
• obtain different audio signals respectively collected by two audio collection devices, wherein one of the two audio collection devices has a specific positional relationship with an effective audio source;
• at least according to the different audio signals respectively collected by the two audio collection devices, determine effective signals corresponding to the effective audio source and noise signals corresponding to a noise source and obtain determination results, wherein determining the effective signals and the noise signals corresponding to the noise source includes:
• determining one group of audio signals corresponding to each audio source from the different audio signals respectively collected by the two audio collection devices, wherein each group of audio signals includes different audio signals generated by a corresponding audio source in the two audio collection devices respectively;
• and
• determining a target group of audio signals based on each group of audio signals, the target group of audio signals being the effective signals corresponding to the effective audio source, and determining the target group of audio signals including:
• determining the target group of audio signals with a largest amplitude variation between the audio signals collected by the two audio collection devices in each group of audio signals;
• and
• perform a noise reduction process on the audio signals collected by at least one of the two audio collection devices to retain the effective signals and reduce the noise signals, according to the determination results.
