How this service works
Takes an episode file (up to 24 MB) and checks it against widely used podcast delivery recommendations: MP3 or AAC container, bitrate of at least 64 kbit/s (mono) or 96 kbit/s (stereo), 44.1 or 48 kHz sample rate, integrated loudness of -16 LUFS ±1 for stereo (-19 for mono), true peak at most -1 dBTP, a title tag present, chapters present (recommendation only), and no more than 3 seconds of silence at the start and end.
Output
A structured report indicating pass/fail status for each checked criterion: container format (MP3 or AAC), bitrate (≥64 kbit/s mono or ≥96 kbit/s stereo), sample rate (44.1 or 48 kHz), integrated loudness (-16 LUFS ±1 stereo / -19 mono), true peak (≤-1 dBTP), title tag presence, chapters presence (advisory), and leading/trailing silence (≤3 seconds).
Example use cases
Pre-distribution episode quality gate
“Before I upload this week's podcast episode, check the file at https://cdn.mypodcast.com/ep100.mp3 against all the standard delivery specs — format, loudness, bitrate, sample rate, true peak, silence, and tags — and tell me what passes and what needs fixing.”
Automated CI check for podcast pipeline
“As part of my podcast production pipeline, run a spec check on the encoded episode file I'm providing as base64 and flag any issues with loudness, silence, or encoding before it moves to publishing.”
Diagnosing loudness rejection by distributor
“My podcast distributor rejected episode 7 — can you check the audio file at https://files.mypodcast.com/ep7.mp3 and tell me specifically whether the integrated loudness or true peak is out of spec?”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/podcast-spec-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically validate a podcast episode against the widely accepted technical delivery standards (loudness, format, bitrate, silence) before distributing to platforms like Spotify, Apple Podcasts, or Amazon Music. Prefer this over manual DAW checks or generic audio analysis tools when you want a structured pass/fail report covering all major spec dimensions in a single API call.
Side effects
- File exceeds 24 MB limit — request rejected
- Unsupported audio format (e.g. WAV, FLAC) — format check fails
- URL unreachable or returns non-audio content — source fetch error
- base64 payload malformed or exceeds size limit — parse error
- File is too short to compute meaningful loudness — analysis error
