Abstract

The invention discloses a method and a device for testing sound quality, and belongs to the technical field of computer. The method comprises the following steps: receiving a sound quality automatic test instruction of a first audio file input by a user; acquiring the spectrogram of the first audio file; and if the color corresponding to a preset standard audio frequency at each audio frame is a default color corresponding to zero loudness in the spectrogram, displaying prompt information indicating that the sound quality of the first audio file is lossy. The method and the device can ensure the user experience of listening to the music.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for detecting sound quality. Background technique [0002] With the rapid popularization of the Internet and the continuous growth of bandwidth, people have higher and higher requirements for music quality, and audio files with lossless sound quality have gradually become the first choice when listening to music. After the song recording is completed, the audio file is generally compressed. The compression is divided into lossy compression and lossless compression, and audio files with lossy sound quality and lossless sound quality can be obtained respectively. Compared with audio files with lossy sound quality, lossless sound quality audio The file contains a larger amount of information and higher fidelity. Generally, the bit rate of an audio file with lossless sound quality is much higher than that of an audio file with lossy sound quality. [0003] When...
