Go from a finished mix to a master you can compare
Mastering is the final processing stage for a finished mix. It shapes tonal balance, dynamics, and loudness across the track. Our online audio mastering studio lets you hear that processing and compare it with your original audio.
Automation gives you a place to start. Presets, meters, and adjustable processing let you take it further. You decide how much weight, brightness, and intensity works for the music you made.
Bring a mix you are happy with. Mastering can refine the overall sound, but it cannot replace the balance and creative decisions made in your mix.
Automated mastering with room for your ears
Choose a mastering preset, listen to your track, and refine the processing with real-time controls. Compare the before and after versions to hear whether the changes support your song. Reference-track analysis can also guide tonal balance and loudness decisions.
Listen to quieter sections as well as the loudest part of the song. Keep the dynamics you want, check the meters, and choose a final level that suits your release.

Questions about online audio mastering
What is AI audio mastering?
Mastering is the final audio-processing step after mixing. Chosen Masters uses AI-assisted analysis and audio processing to help you shape tonal balance, dynamics and loudness. You can listen to the result, adjust the settings and compare it with your original mix.
Can I try online mastering for free?
Yes. You can try the free mastering preview and compare the sound before paying. Free previews include an audio watermark. A clean, watermark-free download requires a paid Master Credit or an eligible subscription.
Can I change the mastering settings?
Yes. Start with a preset, then adjust the processing and loudness while listening. Use before-and-after playback to decide whether the master improves your mix rather than judging it by volume alone.
Can I download my mastered track as WAV or MP3?
Yes. The mastering workspace supports WAV and MP3 exports. Choose the format and available export settings that suit your release after unlocking a clean download.
Does buying one master start a subscription?
No. A single Master Credit is a one-time purchase for one track. Monthly and yearly subscriptions are separate options for artists who master music regularly. Check the selected option and price before paying.
Does mastering replace mixing?
No. Mastering works on the combined mix. Fix problems such as clipping, an overpowering vocal or an instrument balance issue in your mix first, then use mastering to make final adjustments to the whole track.
