Hear the master.

Measured on the file you get back, and level-matched so the comparison is fair. Most tracks finish in 2–10 minutes.

Hear it

Matched to the same loudness.

Both sides of this A/B are matched to the same loudness, so what you hear is tone and dynamics.

What comes back

Your mix and the master, both measured.

Your mix is measured before anything is touched, and the master is measured on the exact file you download — not on a preview, and not on what the target said it should be. Switch sides and watch the same four readings change.

Electronic demo, mastered to its manifest target.

The room

A master, its measurements, and your mix to compare it to.

How it decides

After the upload, four stages in this order, every time.

  1. Measure the mix

    Loudness, true peak, range, tilt and stereo width, on the file as it arrived.

  2. Match a finished record

    The tonal target is a reference chosen for the kind of music this is.

  3. Render to the target

    The loudness you picked, under the ceiling you picked. If it cannot get there under the ceiling, it stops short and states the shortfall.

  4. Measure the file you get

    Every render is checked against its own target before it is offered. The numbers on the page are from that check.

Pick the number

Four loudness targets, three ceilings, four named destinations.

The −2.0 dBTP ceiling is what Spotify asks for once a master is louder than −14 LUFS. The −0.1 column is for a file that is never re-encoded.

Questions

Common questions.

Do I need an account?

Not to hear it. Drop a mix, pick a target, and the finished preview plays in full with both sets of numbers. An account is asked for when you want the file.

What does the preview cost?

Nothing. It is the full master, level-matched against your mix. Payment is for the download, per track or unlimited.

Is the comparison really level-matched?

Yes. Both sides play at the same loudness, so what you hear is tone and dynamics. The readings for each side are shown beside it.

What if the target cannot be reached?

It delivers what it reached without breaching the ceiling, and states the shortfall.

What formats?

WAV, AIFF, FLAC or MP3 in, up to 1 GB and 20 minutes. 24-bit WAV, 16-bit WAV and MP3 320 out, on every paid level.

Can I change my mind?

Run it again at a different target or reference — the preview is free every time. On Unlimited the new master is included; per track, each master you download is its own purchase.
