Company Overview

Songmastr is a powerful AI-based audio mastering service that makes it easier for anyone to master their own tracks - and all without the complexity or hassle of traditional mastering methods. The company offers a free tool that allows users to master up to seven songs per week with ease, and paid packages are available that start at just $4 per track.

The service is based on a powerful open source library called Matchering, which allows the Songmastr algorithm to master your track perfectly, using the same RMS, FR, peak amplitude, and stereo width as a reference song of your choice. This means that the mastering process is incredibly precise, ensuring that every song is given the final polish it needs to shine.

It's important to know that your song must be properly mixed before uploading to ensure the best possible result. Also, Songmastr recommends leaving some volume headroom on your mixed track, and while you can apply some compression, it is important not to apply a limiter as it will be done during mastering.

The reference track you choose must be in the same genre and "vibe" as your song. Vocals are key to the track balance, and if you are mastering a beat or instrumental track, it is best to choose a reference without a singer. If you decide to upload your own reference track, make sure it is of good quality and at a normal commercial volume.

With no software or registration required, Songmastr is both user-friendly and accessible to all, guiding you every step of the way to a perfectly mastered track. The tool allows you to upload a song or beat from your computer and then redirects you to the download page once your mastering is complete. The only limitation to Songmastr's service is that songs must be under 10 minutes and 80MB - small restrictions to ensure that the server doesn't become saturated.

Overall, Songmastr offers an affordable, user-friendly, and powerful solution for anyone to master their songs easily, regardless of their experience level. If you're looking for an easy way to get your music sounding professional and polished, you can't go wrong with Songmastr's AI-based mastering services!
