Last updated: April 2025

What MixMasterAI is

MixMasterAI is a free online audio mastering service available at mixmasterai.co. You upload a raw audio file, choose a genre or character preset, and receive a professionally mastered output file. No account, no subscription, and no payment is required to use the service.

You own your music

You retain 100% ownership of all audio you upload to MixMasterAI. We do not claim any rights, licenses, or ownership over your content at any time. Uploading a file to our service does not transfer any intellectual property rights to us.

You may use mastered outputs for any commercial or personal purpose, including releasing to streaming platforms, selling, licensing for film or video, and radio broadcast.

How we handle your files

  • ·Audio files are stored on our servers only for the duration of processing and download availability.
  • ·All files are automatically and permanently deleted from our servers within 48 hours of processing, with no manual intervention required.
  • ·We do not use your audio files to train, fine-tune, or improve any AI or machine learning models.
  • ·No human at MixMasterAI listens to or reviews your uploaded audio.

Fair use and availability

MixMasterAI is free with no per-track limits. We reserve the right to introduce reasonable fair use limits in the future if needed to keep the service running for everyone. If we do, we will give users advance notice before any limits go into effect. We will never charge retroactively for tracks already mastered.

The service is provided as-is. We make no guarantees of uptime, processing speed, or uninterrupted availability. We will do our best to keep it running, but we cannot promise the service will be available 100% of the time.

Acceptable use

You agree to use MixMasterAI only for audio you have the right to upload and master. Do not upload audio that infringes on someone else's copyright. We reserve the right to suspend access for users who abuse the service or use it in ways that harm others.

Limitation of liability

MixMasterAI is not liable for any loss of files, data, or income resulting from your use of the service. Always keep backups of your original audio files. We are not responsible for the quality of mastered outputs, as results vary based on the source audio and settings you choose.

Changes to these terms

We may update these terms over time. If we make significant changes, we will update the date at the top of this page. Continued use of the service after changes are posted means you accept the updated terms.
