A master is only as trustworthy as the meter behind it. This is what ours does and how we check it.
Integrated loudness is measured in LUFS using ITU-R BS.1770-4 K-weighting with the standard gating. Loudness range (LRA) is measured the same way. The same meter drives the live preview, the loudness targeting and the export, so the number you see is the number that is rendered.
True peak is measured with 4× oversampling, because a file can clip between samples after it is converted to MP3 or AAC. The final limiter is an inter-sample-peak brickwall with look-ahead, so the exported file stays under the ceiling for the platform you chose.
Each platform tab sets its own loudness target, and the render converges on it in a few measured passes: measure, adjust gain, limit, then check true peak again. Streaming sits at −14 LUFS and the vinyl preset at −12 LUFS with a −3 dBTP ceiling. See LUFS explained and the 2026 loudness data.
Before every release an automated gate renders and audits real audio. It compares our meter against ffmpeg on test signals, audits the exported file for loudness, true peak and clicks, and confirms that every platform tab targets correctly. If a check fails, the release does not ship. Changes are listed on the changelog.
Every master gets a 10-category scorecard, so you can see what changed instead of trusting a single number. Hear it against your raw mix before you pay.
