Normalise audio

Bring a recording to a standard loudness so it does not jump against everything else.

Even out the volume now No key, no code — 5 credits either way.

curl -X POST "$DOATHING_API/v1/media/audio-normalize" \
  -H "x-api-key: $DOATHING_KEY" \
  -H "content-type: application/json" \
  -d '{"file": {"filename": "recording.mp3", "content_type": "audio/mpeg", "data_b64": "<base64>"}, "options": {"target_lufs": -16}}'

Bring a recording to a standard loudness so it does not jump against everything else.

Apply EBU R128 two-pass loudness normalisation to a target LUFS.

Input

Send a file object with base64 data_b64, its content_type and a filename. Accepted types: audio/mpeg, audio/wav, audio/ogg, audio/flac, audio/mp4.

The declared type is not trusted — the bytes are sniffed and a contradiction is rejected rather than corrected.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

{
  "target_lufs": -16,
  "measured_lufs": -23.4,
  "measured_true_peak_db": -3.1,
  "two_pass": true,

}

Cost

5 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.

Parameters

Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
