Electronic device and method for playing audio files

Abstract

The invention provides an electronic device for playing audio files. The electronic device is configured with an Android system. The electronic device comprises a receiving unit, a detection unit, a judgment unit, an audio decoding unit and a playing control unit; the detection unit acquires the sampling rate and sampling precision of audio streams which are requested to be played and received by the receiving unit; when the judgment unit determines that the sampling rate and sampling precision are not preset sampling rate and sampling precision, the audio decoding unit decodes the audio streams and adjusts decoded information to decoded information which accords with a preset transmission format; and the playing control unit plays the audio streams according to the adjusted decoded information and a first playing mode. The invention also provides a method for playing the audio files. With the electronic equipment and method for playing the audio files of the invention adopted, when playing audio files with different preset sampling rates, the electronic device can render a realistic effect, and therefore, audio file playing quality of Android equipment can be improved.

Description

technical field [0001] The invention relates to the playing of audio files in an operating system of an intelligent electronic device, in particular to an electronic device and method for playing audio files. Background technique [0002] The existing Android system supports the playback of audio files with all sampling rates and sampling bits, and 44.1KHz is used as the default sampling rate for playing sound. However, for audio files with sampling rates other than 44.1KHz / 16bit, a resampling algorithm is required to achieve 44.1KHz / 16bit. Usually, the use of resampling algorithm for sampling frequency conversion will cause large noise and harmonic distortion, so in the Android system, the playback of high-quality audio files will not be able to achieve the desired effect. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide an electronic device and method for playing audio files, which can improv...
