The mflac and flac formats of QQ music are different in decoding speed.

due to the different encoding methods, the decoding speed of the two lossless compression formats will be affected. Generally, the decoding speed of FLAC is 3% faster than that of APE.

The reason is that FLAC only needs to perform integer operations, and does not need to perform floating-point operations that occupy higher frequency and larger data processing capacity of the system. Due to this structure, general hardware can perfectly realize real-time decoding.

flac format features:

The encoded audio (PCM) data has no information loss, and the decoded audio is the same as every byte of the encoder input. Each data frame has a 16-bit CRC check code of the current frame, which is used to monitor data transmission errors. For the whole audio data, an MD5 for the original uncompressed audio data is also saved in the file header.
