FAQ: AI Mastering
How is AI mastering different from human mastering?
AI mastering is faster, free and private, with results that are professional for most use cases. Human engineers may still beat AI on critical major-label releases where nuanced artistic decisions matter.
Will it ruin my mix?
No — the processing is tuned to enhance, not over-process. You can A/B against your original mix at any time and adjust intensity before exporting.
Is it free?
Yes — completely free, no account required. Process as many tracks as you like, right in your browser.
Do my files get uploaded?
No. All audio decoding, processing and encoding happens locally in your browser using the Web Audio API. Your audio never leaves your device.
What loudness should I target?
Use -14 LUFS for streaming (Spotify, Apple Music, YouTube). Use -9 LUFS only for club or radio formats where extra loudness is expected.
What file formats are supported?
Any format your browser can decode: MP3, WAV, FLAC, OGG, AAC, M4A, WEBM. Export is always 16-bit WAV for maximum quality.
