Method and device for playing audio files

Abstract

The invention discloses an audio file playing method and device, which are used for expanding the number of channel signals of the audio file and improving the playing effect of the audio file when the audio file is played. The method is: after the mobile device obtains the audio file, it will judge whether the audio file contains a channel signal that it can play, and if so, it will play it directly; otherwise, it will convert the channel signal in the audio file into a channel signal that it can play. The sound signal is then played. In this way, when multiple mobile devices are used to play the same audio file, it is possible to prevent each mobile device from performing the same operation. At the same time, the number of channels of the audio file is increased, and the sound field of the audio file is expanded. Improved playback of audio files.

Description

technical field [0001] The invention relates to audio processing technology, in particular to an audio file playing method and device. Background technique [0002] In recent years, smartphone users and users of handheld tablet devices have increased. Most of the music playback of traditional mobile devices is carried out on the same device. Playing the same piece of music collaboratively through multiple mobile devices can increase the volume or expand the sound field to improve user experience. However, the number of audio files widely used by users (such as MP3) is generally monophonic or dual-channel (ie stereo), and the number of audio files in multi-channel format (eg, 5.1) is relatively small. If multiple mobile devices are simply used to play the same audio file, the volume of the audio is only increased, and the sound field of the audio cannot be expanded. [0003] For example, the first solution in the prior art is: two or more mobile devices are used to play a ...

AI Technical Summary

Problems solved by technology

[0006] However, using multiple mobile devices to play each channel signal of a 5.1-channel audio file separately, although the number (multiple) of channel signals played is more than that of mono and stereo signals, it only increases the playback volume. It cannot increase the number of extended channel signals, that is, the original audio file is required to be multi-channel

If the original audio file is stereo or mono, there is no way to convert it into multi-channel for playback in real time
