Attention!

MAAT DROffline log file format is now supported!

DROffline is the official successor (see here) to the old TT DR Offline Meter with a new and improved measuring algorithm. Check out the official website:

MAAT DROffline

Be sure to check the corresponding checkbox in the upload form to mark an album as measured with DROffline! This is important because the results of the two algorithms differ quite much.

This site is not affiliated with the Pleasurize Music Foundation (PMF) or MAAT in any way. This is a one-person non-profit project.
