One pass, three results

Loudness delivery without the chore

Measure, conform and prove a whole batch in the order you actually work - not file by file.

01  Measure

Every number your spec asks for

Drop in files or folders and get Integrated loudness, True Peak and LRA for each one, checked against the delivery preset you picked. WAV, AIFF, MP3, M4A/AAC, or the audio track of MP4/MOV.

02  Conform

Linear gain, dynamics untouched

One click applies a true-peak-safe linear gain to hit the target: no limiter surprises, no recompression. Files that already comply are left alone - and the report says so.

03  Prove

A QC report the client can file

Export a clean PDF or CSV per batch: per-file measurements, targets, pass/fail - ready to attach to the delivery email.

Delivery specs

Presets that match the real world

Pick the platform, and the target and true-peak ceiling are set for you.

Or define your own target and tolerance and save it as a preset. Conformed files are written as 24-bit WAV at the source sample rate.

Local by design

Your audio never leaves the Mac

Client material stays client material. LoudPass is built so that uploading is not a setting you toggle - it is impossible by construction.

No network access

The app is sandboxed without any network capability. It cannot upload, phone home, or check in.

No account, no telemetry

Nothing to sign into, nothing tracking you. The App Store privacy label reads "Data Not Collected".

Reports stay yours

PDF and CSV reports are written to the folder you choose and go only where you send them.
