Multi-op Audio Pipeline

Chain up to 10 audio operations in a single execution, eliminating intermediate uploads.

When to use

• Trim then transcode — cut a segment and immediately re-encode it.
• Complex workflows — multiple dependent steps without round-trip overhead.
• Atomic processing — all operations succeed or the whole pipeline fails cleanly.

Inputs & outputs

Input modality	Audio file (URL)
Output modality	Audio file (GCS URL)
Max operations	10
Max input size	2 GB

Parameters

Param	Required	Description
operations	yes	Ordered array of 1–10 operation objects. Each object is one of: { trim }, { transcode }, { concat }.

Each operation uses the same parameter shape as the corresponding standalone capability.

Examples

Trim first 30 s, then convert to MP3

{
  "type": "audio.pipeline",
  "input": { "audio_url": "gs://infery-prod-media/example/recording.wav" },
  "params": {
    "operations": [
      { "trim": { "start": 0, "end": 30 } },
      { "transcode": { "format": "mp3", "bitrate": "192k" } }
    ]
  }
}

Transcode to AAC at reduced bitrate

{
  "type": "audio.pipeline",
  "input": { "audio_url": "gs://infery-prod-media/example/master.flac" },
  "params": {
    "operations": [
      { "trim": { "start": 10, "end": 120 } },
      { "transcode": { "format": "aac", "bitrate": "128k" } }
    ]
  }
}
