What are the commonly used encoding methods?

Answer: Common encoding method: VBR (Variable Bitrate) dynamic bit rate means that there is no fixed bit rate. The compression software immediately determines what bit rate to use according to the audio data when compressing. This is a method that takes into account the file size on the premise of quality. encoding mode;

ABR (Average Bitrate) is an interpolation parameter of VBR. LAME created this encoding mode in response to the poor file volume ratio of CBR and the variable size of VBR generated files. Within the specified file size, ABR takes every 50 frames (about 1 second for 30 frames) as a segment. Low-frequency and insensitive frequencies use relatively low traffic, and high-frequency and large dynamic performance use high traffic, which can be used as VBR and CBR. a compromise choice.

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