When uploading, input any reference song that's on Spotify. CarMaster integrates with Spotify so we know the subgenre of each song in their catalogue, and then your song is mastered according to the subgenre.
To sell your song-rights to a TV show, commercial, or movie, their Music Supervisor may request a properly mastered version. CarMaster has you covered

CarMastering is the process of making your song sound professional in the car. Before CarMastering, your song may be missing certain bass frequencies, and even have sonic interference from the left and right speakers, causing certain sounds to be inaudible. CarMastering also makes sure you song can be played loudly in the car, without distortion.
Other solutions focus on generically mastering your song, while CarMaster specializes in making sure your song will sound great in the car. We make sure the stereo image and frequency response of your song is perfect. Of course, a CarMastered song will sound good anywhere, but our #1 priority is the car. We also enable you to choose any reference song from Spotify, and master your song accordingly
Yes. Our mastering algorithm currently does not use any machine learning, and has never been trained on any artist's songs. We will never use any songs uploaded to train generative AI models. When users upload, they are shown a clear opt-in form to allow us to use their song to train an AI mastering machine learning model in the future. They do not have to opt-in to use our service. The Spotify reference feature does not rip songs from Spotify. Instead, Spotify's API returns the subgenre of each song, and we master accordingly.
No. You maintain all rights to your song. Our business model is charging directly for the AI mastering.
