Songmastr is an AI-based automatic song mastering service that allows users to instantly master their songs to a commercial reference track. The service is free up to 7 songs per week, and is powered by the open source library Matchering. The algorithm applies the same RMS, FR, peak amplitude and stereo width as the reference track chosen by the user. The service does not require any software or registration and is easy to use – simply upload a song or beat from your computer and the processing will begin, after which the download button will appear and the song can be downloaded. The service only accepts songs of up to 10 minutes and 80MB in length due to server limitations, and users can view examples of audio mastering in the examples section.
