Check your set before the gig

Up to 50 tracks side by side: how loud each one is, the trim that levels it with the rest, its true peak, and one line on the file itself. Checked on your own computer; nothing is uploaded.

Open Set check

What you see for each track

  • Integrated loudness in LUFS: how loud the whole track plays, the figure two tracks are levelled on.
  • Loudness range in LU and PSR: how much it moves, and how punchy or how squashed it is.
  • True peak in dBTP: the top of the waveform, including the peaks between the samples that clip a club system’s converter.
  • The gain trim in dB: what to add or take off on the channel so this track plays at −8.0 LUFS, the middle of the Club/DJ range, or at the middle of your own set.
  • One line on the file: File OK, or lossy source suspected (a WAV, AIFF or FLAC that was an MP3 before, or an MP3 that claims 320 kbps and was made from less), clipping, cut-off ending or dead air.
  • The tracks that stand out: any track more than 2 LU from the set’s middle, or with a PSR more than 3 LU from it, is named in a plain line, such as “much quieter and more dynamic than the rest”.

How it works

  1. Open Set check in the app and drop the tracks: WAV, AIFF, FLAC, MP3 or M4A.
  2. Each is measured on your computer while you watch; a set of 50 takes a couple of minutes.
  3. Sort by any column, switch the trim between the club target and your set’s middle, and export the table as CSV for your notes.

Plan

  • Set check is part of DJ, at €9 a month or €79 a year in the EU, and of Studio. Pricing has the price for your country.
  • DJ starts with a 3-day trial. Cancel in those three days and nothing is charged.

Questions

Are my tracks uploaded?

No. Set check measures them in your browser, on your computer. Promos and unreleased tracks never leave it.

Is this the same as auto gain?

No. Auto gain changes the level as a track loads and does not say why. Set check tells you before the gig how loud each track is, what to trim, and which file has a problem.

Which formats work?

WAV, AIFF, FLAC, MP3 and M4A (AAC) in every current browser. A file the browser cannot read says so in its row.

Are the figures the same as in a full report?

Yes. Set check uses the same measurement as every RefBooth report.

One file in detail: the fake FLAC checker, the fake 320 checker and the clipping checker. The background: LUFS for DJs and gain staging for DJs.
