What is the difference between flac and mp3
First, the sound quality is different.
1. flac: It will not destroy any original audio information, so you can restore the sound quality of music CD.
2, mp3: is designed to greatly reduce the amount of audio data. Using MPEG Audio Layer 3 technology, music can be compressed into a smaller capacity file with a compression ratio of 1:10 or even 1:12.
Second, the audio is different.
1. flac: After compressing the audio with FLAC encoding, no information will be lost. After restoring the FLAC file to a WAV file, the content of the WAV file before compression is the same.
2. mp3: The human ear is not sensitive to high-frequency sound signals. The time domain waveform signal is converted to a frequency domain signal and divided into multiple frequency bands. Different compression ratios are used for different frequency bands, and the high-frequency compression ratio increases (even ignoring the signal) uses a small compression ratio for low-frequency signals to ensure that the signal is not distorted.
