Understanding the Trim Audio Endpoint

The Trim Audio endpoint allows you to trim an audio file to a desired length while optionally applying a fade-out effect. This is particularly useful for applications that need to prepare audio clips for various use cases such as podcasts, music playlists, or sound bites.

  • Effortlessly trim audio files to a specified duration.
  • Optional fade-out for smoother transitions.
  • No need for local FFmpeg installations or complex setups.

Using the Trim Audio API

To use the Trim Audio feature, you will interact with the endpoint using a POST request. Here are the parameters you need to provide:

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

2. **desired_length**: The length of the trimmed audio in seconds (required).

3. **fade_duration**: Optional parameter for the duration of the fade-out effect (default is 0 seconds).

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

url = 'https://www.ffmpegapi.net/api/trim_audio'
data = {
    'audio_url': 'https://example.com/song.mp3',
