How it works

Three steps, zero uploads

1. Drop your mix

Bounce your final mix (leave 3 to 6 dB of headroom if you can) and drop it in. Nothing is uploaded; the tool works right here in your browser.

2. We master it

The chain measures LUFS loudness, applies gentle corrective EQ and glue compression, hits your loudness target and finishes with a lookahead true-peak limiter.

3. Download & release

Grab your 24-bit / 48 kHz WAV, streaming-safe and release-ready for Spotify, Apple Music and every distributor.

Questions

Free mastering FAQ

Is this mastering tool really free?

Yes. Studio-Quality Masters is completely free, with no accounts, no watermarks and no limits on how many tracks you master. It is Eze Collective's gift to independent artists.

Does my track get uploaded to a server?

No. All processing happens locally in your browser using the Web Audio API. Your unreleased music never leaves your device, which also means there is no file-size queue and no waiting.

What do I get back?

A hi-res 24-bit / 48 kHz WAV file, loudness-normalised for streaming with a true-peak safe ceiling, ready to release on Spotify, Apple Music and every other platform or distributor such as DistroKid.

What does the mastering chain do?

The chain measures your track's loudness (ITU BS.1770 LUFS), applies gentle corrective EQ and glue compression, normalises to your chosen loudness target and finishes with a lookahead peak limiter, so the master sounds great on speakers, headphones and car stereos.
