Where does the annual song accompaniment come from?

It can be downloaded from many music apps.

For example, install QQ music and national karaoke software on your mobile phone, use QQ music to find the desired song accompaniment, scroll the music interface to the left, and click the microphone icon next to the barrage to enter the national karaoke page.

When the music is over and the end page pops up, turn the volume to the lowest and the accompaniment to the highest. Don't click Publish, click Save.

Open QQ, click on the avatar, find my file, send it to the computer, open the file path, and the accompaniment just now is in it.

The PC receives it, saves it to the desktop, opens the format factory, converts it to mp3, selects m4a as the format file, and then converts it.
