AudioLinter MT4API.devAudioLinter's answer
Most loudness tools are standalone apps or require exporting to an external service. AudioLinter runs where podcasters already publish โ WordPress โ and fixes the file in place. EU-hosted, uploaded audio deleted within 48 hours, free analysis tier with no card required.
AudioLinter's answer
It checks and fixes podcast loudness (EBU R128, โ16 LUFS), true peak (โ1 dBTP) and dead air directly inside the WordPress post editor โ no separate app, no file upload to a third-party dashboard. One-click repair, not just a report.
AudioLinter's answer
Built by a solo developer in Germany who kept seeing podcast episodes rejected or downranked for loudness/true-peak issues that a simple automated check could catch before publishing. Built directly into the WordPress workflow podcasters already use.
AudioLinter's answer
PHP/WordPress plugin frontend, Python/FastAPI backend for audio analysis (EBU R128 loudness, true-peak metering), Next.js marketing/account site, self-hosted on Hetzner (EU).
AudioLinter's answer
Independent podcasters and small podcast networks who self-host on WordPress (often via Podlove or similar plugins) and want their episodes to meet Spotify/Apple/YouTube loudness specs without hiring an audio engineer.
