Free Tools
Technical reference for the free beat tools from Spectralite, which send tempo and beat to other software.
The free tools listen to music and send its tempo and beat to the software you already run. They share one beat tracker, so a track locks at the same tempo in every one of them. Product overviews and downloads are on the Free tools page of the website.
