摘要： The present disclosure provides a method for chorus mixing, an apparatus, an electronic device and storage media. The method includes 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.

摘要： A lead tone is generated on the basis of an input tone signal. Meanwhile, a specific pitch of the input tone signal is sequentially detected, from which is detected a normalized pitch corresponding to any one of the musical pitch names. Then, difference information is obtained which pertains to a difference between the specific pitch and the normalized pitch, and a pitch having a given pitch interval from the normalized pitch is determined as a target pitch of a tone signal to be generated. Then, a harmony tone is generated which has a pitch obtained by modulating the target pitch in accordance with the difference information.

摘要： An audio apparatus is suitable for generating crowd sounds from an audio signal is disclosed in which the apparatus comprises modulation means operable to modulate a noise signal in response to the audio signal to generate a modulated noise signal, and diffusion delay means. The diffusion delay means is operable to apply a series of two or more delay operations, the input signal to a first such delay operation in the series being the modulated noise signal, and input to each subsequent delay operation in the series being the output signal generated by a preceding delay operation. Each delay operation comprises modifying that operation's input signal by the addition of a delayed version of that operation's input signal.

摘要： Spectrum envelope of an input sound is detected (10). In the meantime, a converting spectrum is acquired which is a frequency spectrum of a converting sound comprising a plurality of sounds (30), such as unison sounds. Output spectrum is generated by imparting the detected spectrum envelope of the input sound to the acquired converting spectrum (13). Sound signal is synthesized on the basis of the generated output spectrum (40,63). Further, a pitch of the input sound may be detected (12), and frequencies of peaks in the acquired converting spectrum may be varied in accordance with the detected pitch of the input sound (21). In this manner, the output spectrum can have the pitch and spectrum envelope of the input sound and spectrum frequency components of the converting sound comprising a plurality of sounds, and thus, unison sounds can be readily generated with simple arrangements.
