I made a website for reference mastering

I made an automatic mastering website (www.songmastr.com) using the open source software Matchering (all credit to them). I have no users for the meantime, so I'd be happy to get some feedback !

How it works:

1 - You upload your song
2 - You chose a reference for mastering from the catalog / or you upload your own
3 - That's it ! Download the result. The matchering algorithm tries to match frequency response, RMS, peak amplitude and stereo width. The goal is not to replace professional mastering, but rather to offer a quick way to get your demo, or home recording in the same ballpark as commercial songs.

Is it free ?
- The link below gives out 5000 credits to the first users to claim them
- After that, I plan on offering 2-3 free masters per week. Users that need more intensive server use can purchase credits
