AI Mastering (masteringo.net) is a small, honest product: an AI-powered online mastering service built by one person. You upload an MP3 or WAV, pick one of 11 style patterns — and up to 3 variants per track if you want options — and get back polished masters in minutes. Three processes are free every day; a 24-bit WAV download is $5 per variant when you need the full-resolution file. No subscriptions, no seat licenses.
Why this service exists
Most online mastering tools push monthly plans even if you release one song a quarter — and several of them quietly limit or throttle AI-generated uploads in their terms of service. Meanwhile the people making music with generative tools (Suno, Udio and similar) need exactly what any artist needs: a clean, loudness-correct master that streams without clipping.
This product answers three questions directly:
- What does it cost? Per track. $5 for the 24-bit WAV when you want it — not a monthly fee you pay whether or not you release.
- Will it handle AI-generated songs? Yes. Mastering Suno and other generated output is one of the main use cases this service was designed around, with no special fine print against it.
- Who actually runs it? One developer (me) who answers support email personally — see Privacy for how your audio files are handled: masters auto-expire after 24 hours unless you keep them, and downloads are only ever available to the account that created the track.
How mastering works here (without marketing fluff)
The engine is AI-powered and reference-based: each style pattern trains toward a specific sonic profile, and up to 3 variants of your track are produced per upload so you can A/B them instead of hoping. Loudness targets follow current streaming practice — around −14 LUFS integrated for Spotify-style delivery with true peak kept under the platform ceiling — which you can verify yourself in seconds with our free browser loudness meter. The difference between that free measurement and a full master is exactly what this service sells: tonal shaping, dynamics and limiting done as one chain, not just gain.
Fair-use principles we keep
- Free tier for real people — 3 processes per day, no card required.
- Paid output is yours: download the MP3 free once your track completes, buy the WAV only if you need 24-bit delivery to a distributor.
- No dark patterns on pricing pages and no upsell pop-ups mid-workflow.
