1. File size:

High quality means high bit rate. For example, MP3 files of 192mps and above, standard quality generally refers to sound files of 128mps and below. The intuitive difference is the size of the file. The higher the bit rate, the larger the file and the better the quality.

2. Sound quality:

The higher the sound quality, the higher the bit speed, making the music fuller. But it is also inevitable that the higher the bit speed, the larger the music file will be. High-quality format: Another type of audio compression is called lossless compression, which can compress the audio file into a smaller size while preserving 100% of all data in the original file. After restoring the compressed audio file, it can Achieve the same size and the same bitrate as the source file.

3. Sampling rate:

The sampling rate of standard-quality music is low, resulting in a low degree of music restoration. The size of standard-quality music files is generally less than 5M. Kbps bit rate refers to the amount of information that can pass through in a data stream per second.

Extended information:

Common encoding modes for high-quality and standard-quality music:

VBR (Variable Bitrate) dynamic bit rate, that is, there is no fixed bit rate. The compression software instantly determines what bit rate to use based on the audio data during compression. This is based on quality and file size. The encoding mode is recommended;

ABR (Average Bitrate) average bit rate is one of VBR interpolation parameters. LAME created this encoding mode specifically for the poor file volume ratio of CBR and the variable size of files generated by VBR.

ABR takes every 50 frames (30 frames about 1 second) as a segment within the specified file size. It uses relatively low traffic for low frequencies and insensitive frequencies, and uses high traffic for high frequencies and large dynamic performance. , can be used as a compromise choice between VBR and CBR.

CBR (Constant Bitrate) means that the file has a bit rate from beginning to end. Compared with VBR and ABR, the file size it compresses is very large, and the sound quality will not be significantly improved compared to VBR and ABR.
