Songmastr - Automatic Song Mastering To Reference.Songmastr
Songmastr is a free online service that uses artificial intelligence to automatically master any song you upload. It can master up to 7 songs per week for free, and for more you can purchase a paid plan starting at $4. To use the service, you need to upload your song and a reference track - a song in the same genre as your own that you want your song to sound like. The service will then master your song with the same RMS, FR, peak amplitude and stereo width as the reference track. Your song must be properly mixed before uploading, with some compression but no limiting. The service does not require any software or registration and it can only process songs up to 10 minutes long and 80MB in size. Once the mastering is done, you can download the file from the download page.
