AUTOMATIC AUDIO HARMONIZATION BASED ON PITCH DISTRIBUTIONS

摘要

Two audio samples and/or sets of audio samples are identified. The pitch distributions of the audio samples and/or sets of audio samples are identified, the pitch distribution of an audio sample or set of audio samples referring to how much of each of multiple pitches of notes is present in the audio sample or set of audio samples. Based on the pitch distributions of the audio samples and/or sets of audio samples, at least one pitch of one of the audio sample and/or set of audio samples can be automatically adjusted (but need not be, depending on the pitch distributions) to increase harmonic coherence of the audio samples and/or sets of audio samples.

主权项

1. A method comprising:
obtaining a first pitch distribution of first audio, the first audio comprising an audio sample or set of audio samples; obtaining a second pitch distribution of second audio, the second audio comprising an audio sample or set of audio samples; determining, based on the first pitch distribution and the second pitch distribution, a pitch shift to increase harmonic coherence of the first audio and the second audio; and using, by a device, the pitch shift to increase harmonic coherence of the first audio and the second audio.
