We have talked about Soundtools' innovative online mastering service, Matchering, before - you can read about it here https://ask.audio/articles/this-new-online-service-uses-reference-track-to-instantly-master-your-mixes.
Unfortunately they were not able to make it into the success they had hoped, and explain some of the reasons here. But there is some good news - now the company has decided to share its secret algorithm on Github for anyone to view and try out, which you can do at https://github.com/SOUNDTOOLS/Matchering
'We're glad to share source code of closed Matchering project by SOUND.TOOLS to you. Matchering was a novel online mastering service with a simple idea - you should upload 2 tracks:
The result of Matchering is the TARGET track with the same RMS, FR, peak amplitude, stereo width as the REFERENCE track has.
We developed the unique automatic flexible processing algorithm, which offers a novel online mastering experience, where you show us: how your track should sound by sending the REFERENCE."
Matchering will make your track sounds like you want:
And now you can make your own mastering using Matchering at home.
