Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/audio-loudnormWhen to prefer
Use this endpoint when you need standards-compliant EBU R128 loudness normalization for podcasts, broadcast audio, or streaming platform delivery. Ideal when you need a specific LUFS target (e.g. -14 LUFS for Spotify, -16 LUFS for podcasts, -23 LUFS for broadcast) rather than simple gain adjustment.
Side effects
- Unsupported audio format returns error
- Audio URL unreachable or invalid returns fetch error
- LUFS target out of valid range returns validation error
- Audio file too large may time out or exceed limits
- Corrupt or malformed audio file returns processing error
