What are the softwares for free music?

Because of the problem of music copyright, not all songs can be downloaded for free at present, and mainstream music software basically has both paid songs and free songs. Others only need to pay for online listening and downloading. If you can't find your favorite songs on a software, you can try to download more music software to find the corresponding resources.

For example, Baidu Music, QQ Music, Cool Dog Music, Xiami Music, Everyday Music, Cool Me Music, Netease Cloud Music, etc.

List of music file formats

1, classical wave

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

There are mono and stereo channels, and the sampling frequency is generally11025hz (11khz), 22050Hz(22kHz) and 44 100Hz(44kHz). Capacity of waveform file = (sampling frequency × sampling bits × number of channels) × time /8( 1 byte =8bit).

2. Traditional mode

MOD is a music format similar to wave table, but its structure is similar to MIDI, and it adopts real sampling, which is very small. In the previous DOS era, MOD was often used as the background music of games. At present, MOD can contain multiple tracks in various formats, such as S3M, NST, 669, MTM, XM, IT, XT, RT and so on.

3, computer music MIDI

MIDI is the abbreviation of musical instrument data interface, which records the sound of musical instrument in digital form (each note is recorded as a number), and then synthesizes these records through FM or wave table when playing: FM synthesis is to mix the sounds of multiple frequencies to simulate the sound of musical instrument.
