About Audio Audit
Audio Audit is automated quality checking for podcast networks. It checks every episode in every feed for loudness, noise, silences and metadata, then fixes what it finds.
What Does Audio Audit Do?
Audio Audit measures each episode against the standards podcast apps and listeners expect: loudness (LUFS) and true peak, noise floor and unwanted noises, long silences, swearing against the explicit flag, encoding, ID3 tags, cover art and chapters. You can upload a file before you publish, or point Audio Audit at a feed and it checks each new episode as it appears, then emails a report.
When a check fails, Enhancements can fix it: noise reduction, compression, loudness normalisation and metadata, in one pass with no re-upload. Each step is measured signal processing. Nothing is synthesised and no voice is altered, and a fresh report on the enhanced file shows the fix worked.
For teams, Audio Audit has shared workspaces with roles, a REST and GraphQL API, webhooks and a Zapier app, so a network can check dozens of shows without anyone opening each file.
Who Uses Audio Audit?
Podcast networks, broadcasters, production companies and independent podcasters. The Irish Times uses Audio Audit to keep its output consistent. Podnews editor James Cridland has scored his own show with it. One US podcast network checks 14 feeds every day, run by a single technical director.
People at Audible, the BBC, Deezer, Sky and Spotify use it too. Read what customers say on the reviews page.
