Audio signal processing method and device for shared-volume back-box designed stereo system having inverse phase attenuation characteristics

- 27 Oct 2017

TL;DR: In this article, an audio signal processing method and device for a shared-volume back-box designed stereo system having inverse phase attenuation characteristics was proposed, which is used for processing multiple audio signals of the shared volume stereo system.

Abstract: The invention relates to an audio signal processing method and device for a shared-volume back-box designed stereo system having inverse phase attenuation characteristics. The audio signal processing device is used for processing multiple audio signals of the shared-volume stereo system; the audio signal processing device comprises multiple signal processing channels; the signal processing channels are used for separating out high-frequency signal components and low-frequency signal components of the audio signals; the signal processing channels process the low-frequency signal components of the audio signals to generate low-frequency mixed signals; the signal processing channels aggregate the high-frequency signal components of the audio signals and the low-frequency mixed signals to generate multiple audio regeneration signals; and thus, the signal processing channels drive a corresponding loudspeaker in the shared-volume stereo system according to the audio regeneration signals. By means of the audio signal processing method and device, clipping distortion of the stereo system can be avoided; and furthermore, good sound quality can be provided.
