Method for chorus mixing, apparatus, electronic device and storage medium

A method for chorus mixing, comprising:

• obtaining a clean main vocal audio signal from a main vocal audio signal with accompaniment;
• detecting frequency information of the clean main vocal audio signal and frequency information of a chorus audio signal;
• determining a delay between the main vocal audio signal and the chorus audio signal based on time series of the frequency information of the chorus audio signal and time series of frequency information of the clean main vocal audio signal;
• aligning the chorus audio signal with the main vocal audio signal based on the determined delay;
• and
• mixing audio of the main vocal audio signal and the aligned chorus audio signal.

An electronic device, comprising:

• at least one processor;
• at least one memory storing instructions executable by the processor,
• wherein the processor is configured to:
• determine an output mode of a main vocal audio signal;
• in response to determining that the output mode of the main vocal audio signal is a speaker mode, perform actions comprising:
• converting a main vocal audio signal and a chorus audio signal into signals in frequency domain, respectively, wherein the chorus audio signal comprises main vocal audio played by a speaker;
• determining a delay between the main vocal audio signal and the chorus audio signal based on a frequency-domain signal of the main vocal audio signal and a frequency-domain signal of the main vocal audio played by the speaker included in a frequency-domain signal of the chorus audio signal;
• aligning the chorus audio signal with the main vocal audio signal based on the determined delay;
• performing an echo cancellation on the aligned chorus audio signal;
• and
• mixing audio of the main vocal audio signal and the echo-canceled chorus audio signal.
