# Audio Platform Delivery Checker Check podcast or spoken-audio files against platform delivery profiles, including codec, loudness, metadata, chapters, cover art, and decodability. > Canonical page: https://elysiatools.com/en/tools/audio-platform-delivery-checker - **Category:** Media - **Keywords:** audio, podcast, delivery, preflight, lufs, true peak, metadata, chapters, ffmpeg, ffprobe ## Overview Accepts one audio file or a ZIP of up to 20 files. FFprobe inspects the container, codec, sample rate, channels, bitrate, tags, chapters, and attached artwork; FFmpeg verifies decoding and measures integrated LUFS, true peak, and LRA. Results distinguish hard failures from recommendations. Profiles are practical delivery targets, not a replacement for the latest platform documentation. ## Inputs - **Audio File or ZIP Archive** (file): Upload one audio file or a ZIP with up to 20 files - **Platform Profile** (select) - **Strict Mode** (checkbox): Turn platform compatibility warnings into failures; optional chapters and artwork remain advisory. ## When to use - Check a podcast episode before submitting it to a platform. - Verify loudness, true peak, codec, and metadata requirements before delivery. - Review up to 20 audio files together by uploading a ZIP archive. ## How it works - Upload one audio file or a ZIP archive containing up to 20 files. - Select a platform profile or choose All profiles. - FFprobe inspects the container, codec, sample rate, channels, bitrate, tags, chapters, and attached artwork. - FFmpeg verifies decoding and measures integrated LUFS, true peak, and LRA; the JSON report separates failures from recommendations. ## Use cases - Podcast producers can preflight episode files before platform submission. - Audio teams can compare a delivery file with several platform profiles using one report. - Spoken-audio publishers can identify encoding, loudness, metadata, and decoding issues before release. ## Frequently asked questions ### What files can I upload? You can upload one audio file or a ZIP archive containing up to 20 audio files. ### Which delivery profiles are supported? The available profiles are Apple Podcasts, Spotify, YouTube / Music, ACX (Audible), Broadcast / EBU R128, and All profiles. ### What does the checker inspect? It checks audio encoding, loudness, metadata, chapters, attached cover art, and whether the file can be decoded. ### What loudness measurements are included? The report includes integrated LUFS, true peak, and LRA measurements. ### What does Strict Mode do? Strict Mode turns platform compatibility warnings into failures, while optional chapters and artwork remain recommendations. ## Related tools - [Audio Caption Sync Checker](https://elysiatools.com/en/tools/audio-caption-sync-checker): Compare SRT or WebVTT cue timing with likely speech activity and flag timing drift. - [Audio Dictation Quality Checker](https://elysiatools.com/en/tools/audio-dictation-quality-checker): Check whether audio is suitable for transcription using SNR, clipping, format, channels, and speech activity. - [Batch Podcast Publisher Pack](https://elysiatools.com/en/tools/audio-batch-podcast-publisher-pack): Normalize a batch of podcast episodes, apply metadata and chapters, and package validated delivery files in one ZIP. - [Audio Mix Translation Checker](https://elysiatools.com/en/tools/audio-mix-translation-checker): Simulate your mix on phone, laptop, earbud, car, club, mono and noisy-street playback, export every render in a ZIP, and report what survives each system. - [Audio Duration Checker](https://elysiatools.com/en/tools/audio-duration-checker): Get the exact duration of an audio file - [Audio Metadata Viewer](https://elysiatools.com/en/tools/audio-metadata-viewer): View all metadata tags of an audio file - [Audio Audiobook ACX Validator](https://elysiatools.com/en/tools/audio-audiobook-acx-validator): Validate an audiobook chapter or full file against ACX/Audible submission requirements: RMS, peak, noise floor, duration, format, and chapters. - [Audio Concat Validator](https://elysiatools.com/en/tools/audio-concat-validator): Validate concatenated audio files for errors and inconsistencies ## Samples - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Speech Learning & Safety Audio Samples](https://elysiatools.com/en/samples/audio-learning-safety-samples): Deterministic synthetic WAV inputs for pronunciation comparison, dictation preflight, alert degradation, and voice privacy tools. ## Related content - [Podcast Recording, Editing, and Delivery](https://elysiatools.com/en/hubs/podcast-recording-editing-delivery): Rescue remote voices, clean speech artifacts, shape the edit, master loudness, add show assets, and validate podcast files before delivery.
