Abstract

The invention discloses an audio processing method and device. The method comprises steps of: obtaining the sampling point number of each sound channel in multiple sound channels; sampling an audio signal in each sound channel according to the sampling point to obtain sampling data; and obtaining filter data; and carrying out filtering processing on the sampling data according to the filter data. According to the audio processing method and device, the technical problem that sound effects are different in some positions when an audio is played through an earphone in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of audio, in particular to an audio processing method and device. Background technique [0002] The mainstream movie sound production in the market is 5.1-channel or 7.1-channel, which are all played back through speakers with different azimuth angles. [0003] The 5.1 channel refers to the center channel, the front left and right channels, the rear left and right surround channels, and the so-called 0.1 channel subwoofer channel. A total of 6 speakers can be connected to one system. The center channel speaker is responsible for reproducing the actions on the screen. Most of the time it is responsible for the dialogue of the characters; the front left and right channel speakers are used to compensate for actions that are outside the center of the screen or cannot be seen from the screen. and other sounds; the rear surround sound speakers are responsible for the peripheral and the entire background music, mak...
