https://x402.agentutility.ai/audio-loudnormOverview
Normalize audio loudness to a target LUFS level for podcasts, YouTube, and Spotify delivery. Send an audio_url plus an optional target_lufs (defaults to -16) and true_peak, and it probes duration, runs two-pass EBU R128 loudness normalization, and returns a hosted MP3 URL with the applied target and duration in seconds. Common presets: -23 for broadcast, -16 for podcasts, -14 for streaming platforms. Use it as a loudness normalizer, LUFS correction API, or audio mastering step before publishing.
