Embodiment Construction

[0015] like figure 1 As shown, the electronic device 1 in the present invention can convert a multi-channel audio file into a binaural audio file, and can restore the binaural audio file converted from the multi-channel audio file into a multi-channel audio file.

[0016] The electronic device 1 includes a storage unit 11 and a processing unit 12 . The storage unit 11 stores a multi-channel audio file 111 and a binaural audio file 112 , and the binaural audio file 112 is converted from the multi-channel audio file 111 . This multi-channel audio file 111 includes a plurality of channels, such as four channels, five channels, six channels, audio files with different numbers of channels all include left channel part and right channel part, left channel part The audio signal of at least two channels is included, the right channel part includes audio signals of at least two channels, and the number of channels of the left channel part is the same as that of the right channel part....

Abstract

The invention provides an electronic device with an audio file format conversion function. The electronic device is used for converting a multi-track audio file into a dual-track audio file. The multi-track audio file comprises a left track part and a right track part. The electronic device mixes signals of each track in the left track part and the right track part of the multi-track audio file into N paths of similar mixed signals through a hybrid matrix, mixes the N paths of hybrid signals corresponding to the left track part into a left track audio signal in a cross embedding way, and mixes the N paths of hybrid signals corresponding to the right track part into a right track audio signal in a cross embedding way to obtain the dual-track audio file. By the electronic device, the multi-track audio file can be normally played in equipment not supporting the multi-track audio file.

Description

technical field [0001] The invention relates to an electronic device with an audio file format conversion function, in particular to an electronic device and a method for converting a multi-channel audio file into a two-channel audio file. Background technique [0002] Multi-channel audio files, such as Dolby 5.1-channel stereo, reproduce the original characteristics of the sound from different directions very well. However, there are still many devices that do not support multi-channel audio files. Therefore, it is necessary to down-mix the multi-channel audio file into a two-channel audio file to be compatible with the current device. Contents of the invention [0003] In view of this, it is necessary to provide an electronic device with an audio file format conversion function, which can convert a multi-channel audio file into a two-channel audio file. [0004] The electronic device with audio file format conversion function includes a storage unit and a processing un...
