List of music formats

Classic WAVE

As the most classic Windows multimedia audio format, WAVE files are widely used. It uses three parameters to represent sound: sampling bits, sampling frequency and number of channels.

The sound channels are divided into mono and stereo, and the sampling frequencies are generally 11025Hz (11kHz), 22050Hz (22kHz) and 44100Hz (44kHz). The capacity occupied by WAVE files = (sampling frequency × sampling bits × channels) × time/8 (1 byte = 8 bit).

In the previous DOS era, MODs are often used as background music for games. Today's MODs can contain many audio tracks in many formats, such as S3M, NST, 669, MTM, XM, IT, XT and RT, etc.

Computer Music MIDI

MIDI is the abbreviation of Musical Instrument Data Interface. It uses digital means to record the sound played by the musical instrument (each note is recorded as a number), and then , and then synthesize these records through FM or wavetable during playback: FM synthesis simulates the sound of musical instruments by mixing sounds of multiple frequencies; wavetable synthesis stores the sound samples of musical instruments in the sound card waveform table, and then reads the sound from the waveform during playback. The table is taken out to produce a sound.

The leader MP3

MP3 is famous. It uses MPEG Audio Layer 3 technology to compress the sound with a compression rate of 1:10 or even 1:12, with a sampling rate of 44kHz, The bit rate is 112kbit/s.
