Choirless syncs #AloneTogether musicians

Call for Code

While Zoom and other video conferencing services have united us across the globe, these services have a major-drawback for musicians trying to jam remotely during the COVID-19 lockdown: the streams always have some lag making it tough for musicians to sync up.

Enter Choirless, an app using artificial intelligence (AI) to perfectly sync up a series of recordings no matter where they happen. This solution uses the same kind of acoustic analysis that helps the US Masters golf tournament pull highlights.

The team developed the app as part of #CallforCode. The team continue to work on the project and it is finding new users, including this UK choir:

The Choirless team see multiple uses for the app, from bringing together musicians across the world (even after social distancing laws relax) to allowing collaborators to release different versions of a song with different ensembles.
