Document Type and Number:
WIPO Patent Application WO/2024/048492
Kind Code:
A1
Abstract:
This musical instrument identifying method comprises: calculating an acoustic feature amount on the basis of a sound signal; calculating an image feature amount for use in an image recognition technology on the basis of the acoustic feature amount; and outputting information for identifying a musical instrument from the sound signal by using a trained model in which the sound signal and the information for identifying the musical instrument corresponds to each other and which is obtained through training using the image feature amount as an input and the information for identifying the musical instrument as an output.
