How this service works
Normalizes audio levels to target LUFS (e.g. -23 LUFS / -16 LUFS) with integrated peak limiting for podcast, broadcast, and streaming compliance.
Output
Returns a processed audio file or download URL with loudness normalized to the specified LUFS target and peak limiting applied, ensuring compliance with podcast, broadcast (EBU R128), or streaming platform loudness standards.
Example use cases
Podcast episode loudness compliance
“I have a podcast episode at https://storage.example.com/episode10.mp3 — can you normalize it to -16 LUFS with peak limiting so it meets Spotify and Apple Podcasts standards?”
Broadcast TV audio mastering
“Normalize this audio file at https://media.mybroadcaster.com/ad_spot.wav to -23 LUFS to comply with EBU R128 broadcast regulations.”
YouTube video audio leveling
“The voiceover audio at https://cdn.myvideo.com/voiceover_raw.mp3 is way too quiet — can you normalize it to -14 LUFS so it sounds good on YouTube?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/audio/normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need automated, standards-compliant loudness normalization for audio files — especially for podcast production (-16 LUFS), broadcast compliance (-23 LUFS / EBU R128), or streaming platform targets. Prefer this over manual DAW processing when working within an agentic workflow that needs to programmatically process audio files at scale without human intervention.
Side effects
- Invalid or inaccessible file URL returns an error
- Target LUFS value outside allowed range (-70 to -5) returns validation error
- Unsupported audio format may cause processing failure
- Network timeout if source file is very large
- Corrupted audio file may return processing error
