What is Songmastr?
Songmastr is an AI-powered online song mastering service that automatically masters your song (WAV or MP3) to match a commercial reference track of your choice. The tool uses artificial intelligence based on the open-source library Matchering to master your track with the same RMS (root mean square), FR (frequency response), peak amplitude, and stereo width as the reference song you select. Users can either upload their own reference track or choose from Songmastr's catalog of reference songs.
Key features include completely free mastering up to 7 songs per week (364 per year), no software installation required, and no registration needed. The service accepts audio files up to 10 minutes in length and 80MB in size. After uploading a song, users are redirected to a download page where they can retrieve their mastered file once processing is complete. The mastered songs and uploaded files are stored for only 24 hours, and users retain full property rights to their music.
Songmastr is designed for musicians, producers, beatmakers, and audio creators at semi-pro or amateur levels who want to improve their tracks before sharing online. It works on both songs with vocals and instrumental beats (with the recommendation to use vocal-free reference tracks for beats). The tool serves as a cost-effective alternative to professional mastering services like LANDR, Dolby Mastering, and Moises.ai, making professional-sounding mastering accessible to creators on any budget.

Frequently asked questions about Songmastr
What is mastering?
Mastering is the final stage of audio production. The process of putting the finishing touches on a mixed song by enhancing the overall sound, and preparing it for being listened to on a variety of devices. This often involves applying EQ, compression, limiting, saturation, and altering stereo imaging on the mixed track.
How does this service work?
This service relies on algorithms to master your song as closely as possible to the reference track. It uses the open source library Matchering. The algorithm masters your track with the same RMS, FR, peak amplitude and stereo width as the reference song you choose.
Is it free?
It is free up to 7 masters per week (i.e. 364 per year). If you need to process songs more frequently, you can purchase credits through the available credit packs.
How to prepare my song before uploading?
To get good results, spend time on your mix until it sounds good to you. Look at mastering like the final polish. Also don't apply any limiter on the master, as limiting will be conducted during the mastering process.
Does it work on beats?
Sure. If you use the catalog reference, make sure to use reference tracks without vocals (search for beats). For beats or instrumental tracks, a reference without a singer is preferable.
How does this compare to professional mastering?
This is an automated process. It can be a cheap and effective way to improve a semi-pro or amateur track before sharing it online; but it will not go into the intricacies of professional mastering performed by human engineers.
How to choose the reference song?
Ideally, the reference song is a recording that sounds good, and which is similar to the track you are trying to master. Similar includes song genre, instrumentation (in particular voice or no voice), and dynamics. The reference should be within the same genre and vibe as your song.
What do you do with the music uploaded by users?
Your music and the resulting mastered song are stored for 24 hours after upload. You retain the entire property of the music you upload. The service does not hold any claim on the files processed.
How long does my master track stay available?
The mastered song stays available for 24 hours after processing is complete. You can download it by clicking on the download button on the download page.
How does this compare to LANDR, Dolby mastering, and Moises.ai?
As of the writing of the FAQ and to the best of their knowledge, Moises.ai uses the same algorithm (Matchering) for reference mastering. Songmastr offers a generous free tier compared to these services, with 7 free masters per week and no registration required.
