Reverse an audio file so it plays backwards.

Reverse Audio

Reverse an audio file so it plays backwards.

API Endpoint

POST /api/v1/tools/audio/reverse-audio

Accepts multipart form data with an audio file and a JSON settings field.

Parameters

This tool has no configurable parameters. The entire audio file is reversed.

Example Request

curl -X POST http://localhost:1349/api/v1/tools/audio/reverse-audio \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@audio.mp3"

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/audio.mp3",
  "originalSize": 4500000,
  "processedSize": 4500000
}

Notes

• The full audio track is reversed from end to start.
• Output usually keeps the input container. AAC input is written as M4A, and unsupported decode-only inputs fall back to MP3.
