Playback Check

Hear a video the way each device plays it

A video goes in; you hear it through seven modelled devices and get its loudness, true peak and range against YouTube's −14 LUFS.

You give it: One video or audio file, up to 1 000 MB
You get back: A report: integrated loudness, true peak, range, per-device rows, suggested fixes with the number each comes from
Where it runs: Runs in your browser

Open Playback Check

What you get free

The first three minutes of any file, all seven devices, every number and every suggestion.

What it doesn't do

The device responses are models of typical devices, not measurements of a particular product, and the page says so. The voice-over-bed figure is an estimate.
Anything the browser can decode: MP4, MOV, WebM, MKV, MP3, WAV, AAC, FLAC, OGG. Some codecs inside video containers cannot be decoded in a browser; the tool says so and asks for the audio track.

What it costs

Playback Check is free to use today, and there is nothing to buy. It is planned to be part of the $19/month Avyth subscription, which covers every tool with a recurring job — Invoice Splitter, SlipMatch, FBA Gap Auditor, Article 50 Check and Playback Check — not a separate charge for this one tool — it would add: The whole file, however long; the free tier measures the first three minutes.

It isn't built, so there is no checkout on this site and no way to be charged. When it exists it will appear on the updates page, with the date.

If it doesn't work

Email support@avyth.com and the person who built Playback Check reads it. If it fails on your file, say what the file looks like — that is usually enough to fix it.
