Summary

Re-encodes each input audio file at the selected bitrate while preserving its detected format. The result includes the converted audio in a binary property and metadata about the input and output sizes and formats.

Inputs

  • Binary Property — Binary property containing the input audio file; defaults to data.
  • Bitrate — Target audio bitrate: 64, 128, 192, 256, or 320 kbps; defaults to 128 kbps.
  • Output Binary Property — Binary property to store the converted audio; defaults to data.

Output shape

One output item per input item, each with a JSON object and an audio binary property.

JSON includes operation, inputFormat, outputFormat, inputSize, and outputSize. The output file keeps the detected input format and uses the input filename with its extension replaced accordingly. Requires FFmpeg to be available; processing errors are reported as node errors.
