Abstract

The invention provides a method of adjusting an audio output and an audio playing device. The audio playing device comprises a sampling unit. According to the method, the audio playing device adjusts a sampling frequency of a current audio file by the sampling unit based on an audio frequency in the current audio file obtained from a playlist; and decoding processing and audio restoration of the current audio file are conducted based on the sampling frequency. As for the decoding and restoration of the audio frequency of the audio file, the invention solves the problem of sound quality distortion as the audio source needs to be resampled due to the fixed audio output frequency in the prior art.

Description

technical field [0001] The present invention relates to audio decoding technology, in particular to a method for adjusting audio output and an audio playback device. Background technique [0002] Different formats of audio files, or can be encoded with different audio frequencies to maximize audio quality. However, the current audio playback device adopts a fixed audio frequency output method, so that audio files with different audio frequencies need to be correspondingly converted into analog audio signals of the same fixed audio frequency for output, which causes the audio signals to be destroyed during audio frequency conversion. Among them, the way of audio frequency conversion mostly adopts the way of resampling the audio file. Since the audio frequency and the resampling sampling frequency are not a certain integer multiple, there must be noise components in the resampled audio signal, so that the sound quality cannot be guaranteed when the audio is output. In order ...
