Abstract

An audio signal processing apparatus and an audio signal processing method thereof are provided. The audio signal processing apparatus is configured to receive an audio signal and divide the audio signal into a plurality of frames. The audio signal processing apparatus is also configured to apply Fourier Transform on each of the frames to obtain a plurality of acoustic spectra. The audio signal processing apparatus is also configured to apply Fourier Transform again on each of component combinations corresponding to respective acoustic frequencies in these acoustic spectra to obtain a two-dimensional joint frequency spectrum. The two-dimensional joint frequency spectrum has an acoustic frequency dimension and a modulation frequency dimension. The audio signal processing apparatus is also configured to calculate at least one feature of the audio signal according to the two-dimensional joint frequency spectrum.

Description

technical field [0001] The invention relates to a treatment device and a treatment method thereof. More specifically, the present invention relates to an audio signal processing device and an audio signal processing method thereof. Background technique [0002] With the rapid development of digital music on the network and personal devices, how to manage the large amount of music collected has become very important. In order to manage a large amount of collected music, it is often necessary to attach various information to each piece of music. Additional information such as singers, albums, music titles and the like can be added. However, these traditional additional information cannot satisfy some special applications, such as music therapy. Instead, the additional information should also include the music genre (musicgenre) capable of describing the music content and / or the music mood (musicmood) capable of describing the essential emotion of the music. [0003] In ord...
