Audio metadata

Node catalog Transformations

On this page

Read audio duration, codec, sample rate, channels and bitrate.

Usage and specifics

Supply source audio and conversion, trim, volume or metadata settings. Processing requires backend media tools. Keep format and MIME type consistent when mapping.

Technical type : audio_metadata. Runtime : nodulz.

Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the credentials guide if a remote source or execution target requires access.

Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

Parameter	Type	Default	Values / limits

Configuration help

input Audio source: HTTP(S) URL, base64, data URL or complete HTTP or audio node output. Local files are not accepted.

Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

json

{
  "input": ""
}

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
