Abstract

The invention provides a method and a system for controlling audio frequency playing. The method disclosed by the invention comprises steps of obtaining a single track audio frequency as a first audio frequency, multiplying a sound intensity value of the first audio frequency with a left position angle coefficient, obtaining a first left audio frequency output intensity value through calculation, multiplying the sound intensity value of the first audio frequency with a right position angle coefficient, obtaining a first right audio frequency output intensity value through calculation, outputting the first audio frequency through a left sound track according to the first left audio frequency output intensity value, and outputting the first audio frequency through the right sound track according to the first right audio frequency output intensity value. The method for controlling audio frequency playing realizes the double-sound-track stereo output of the mono-tone frequency, and does not have to perform recording in a dual-track form in recording the audio frequency, which reduces the recording cost.

Description

technical field [0001] The invention relates to the field of multimedia technologies, in particular to an audio playback control method and system. Background technique [0002] With the rapid development of digital multimedia technology, more and more multimedia technologies are applied to people's lives. [0003] In traditional audio sounding systems, monophonic audio playback systems and dual-channel stereo audio playback systems are commonly used. The single audio playback system has a microphone when recording audio files, and the recorded audio has no position difference, so that the human ear does not feel the stereo effect. And two-channel stereo is to use two sets of microphones in different positions to record audio during sound collection, and use two independent speaker systems to output audio information to the left and right earphones respectively when playing, so that the left ear only hears the left earphone. Channel information, the right ear only hears th...
