When you create a mash, you have the option to cut your snippets to match the rhythm of the background music you have chosen.*
From the mashing screen, tap on "Music"
Select some background music
Toggle on "Adjust seconds to match beat"
If you choose from our default background music selection, the BPM will automatically be detected
If you select your own music, you'll need to set the BPM manually. You can use third-party tools like Tunebat to identify the BPM of the music of your choice.
