Audio & mastering tools

Trust your ears.
Keep the detail in view.

See loudness, peak information and delivery formats beside the version you are working on. Keep the technical checks close to the listening decision.

Same song. Different measurements.

Switch between illustrative mix and master readings. These are labelled sample values, not analysis of the demo audio or a mastering recommendation.

Visual measurement demonstration only. No audio processing or playback takes place here. These values are not delivery targets.

Know what the numbers describe.

Integrated loudness describes overall level, true peak identifies reconstructed peaks, and RMS gives another view of signal level. Available analysis stays with the uploaded version.

  • Integrated loudness in LUFS.
  • True peak in dBTP and RMS in dBFS.
  • Use destination references as guidance, alongside listening.

Compare the mix, not just the volume.

When loudness measurements are available, level-match playback reduces louder versions for a fairer A/B comparison. It does not rewrite the uploaded audio.

  • Keep version comparison inside the song.
  • Retain the original delivery files.
  • Measurements may be unavailable until analysis completes.

A delivery has more than one format.

Keep familiar audio formats, stems and immersive deliverables organised around their version.

  • WAV, AIFF, FLAC, MP3, M4A and OGG; ZIP packages for stems.
  • Dolby Atmos version bundles on Studio and above.
  • Label TV mixes, instrumentals and a cappella files for their intended use.

The details, when you need them.

Loudness measurements

View integrated loudness, true peak and RMS where analysis is available for an uploaded version.

Compare delivery targets

Compare available measurements with target references for your intended destination. Use them as guidance alongside your ears.

Pre-master checks

Review the available peak and loudness information before the next stage of delivery.

Studio plan and above
Audio and delivery formats

Keep WAV, AIFF, FLAC, MP3, M4A and OGG files, plus ZIP packages for stems. Dolby Atmos bundles are available on Studio and above.

Dolby Atmos versions

Drop the ADM master, the binaural render, and the Atmos MP4 together and they land as one version. Clients hear your binaural mix in any browser; in Safari with AirPods or a recent Mac, a Spatial toggle plays the real Atmos file. The master stays download-only.

Studio plan and above
Stem delivery flags

Per-file flags for TV mix, instrumental, and a cappella so the right asset is labelled for the right slot.
