Understanding the Trim Audio Endpoint

The Trim Audio endpoint allows you to download an audio file and trim it to a desired length. This can be particularly useful for creating previews, podcasts, or any other audio clips that need to be condensed.

To use this endpoint, you will make a POST request to the '/api/trim_audio' path with specific parameters including the audio URL, desired length, and an optional fade-out duration.

  • Endpoint Path: /api/trim_audio
  • Method: POST
  • Content Type: application/json or form data

Parameters Required for Trimming Audio

To successfully use the Trim Audio endpoint, you need to provide the following parameters:

1. **audio_url**: The URL of the audio file you wish to trim (required).

2. **desired_length**: The length in seconds to which you want to trim the audio (required).

3. **fade_duration**: An optional parameter that specifies the duration of the fade-out effect in seconds.

Example Usage of the Trim Audio API

Here's a practical example of how to call the Trim Audio endpoint using cURL. This will trim an audio file to 30 seconds with a 2-second fade-out.

Simply replace the `audio_url` with your own audio file's URL.

curl -X POST https://ffmpegapi.net/api/trim_audio \ 
-H "Content-Type: application/json" \ 
-d '{"audio_url": "https://example.com/song.mp3", "desired_length": 30, "fade_duration": 2}'
