Abstract

The invention discloses an audio signal control method and device. Wherein, the method includes: adjusting the control parameters of the dynamic range control module in the playback platform, wherein the control parameters are used to compress the dynamic range of the signal; receiving the audio signal to be played, and using the adjusted control parameters to control the audio signal Perform processing; play the processed audio signal. The invention solves the technical problem in the prior art that the cost of raising the sound loudness is high.

Description

technical field [0001] The present invention relates to the field of sound processing, in particular to an audio signal control method and device. Background technique [0002] Loudness is an objective indicator to measure audio performance, and it is a parameter that all portable devices will focus on. At present, the way to increase the loudness is usually to increase the external power amplifier, provide Boost capability, or replace the single device with higher sensitivity, etc., but no matter which method is used, it is accompanied by an increase in cost, which is for low-cost portable devices. That said, it is a big problem and challenge. [0003] Aiming at the problem of high cost of improving sound loudness in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a method and device for controlling an audio signal, so as to at least solve the technical problem in the prior art t...
