In this article, we will explore the Trim Audio endpoint and how it can be integrated into your workflow.

What is the Trim Audio Endpoint?

The Trim Audio endpoint at FFMPEGAPI.net is designed to take an audio file and trim it to a specified length. This can be particularly useful in scenarios where you need to create clips from longer audio files for use in applications, social media, or any other purpose.

  • No need for local FFmpeg installation or server management.
  • Quickly process audio files with just a few API calls.
  • Supports optional fade-out effect for smoother transitions.

How to Use the Trim Audio Endpoint

To utilize the Trim Audio feature, you'll make a POST request to the /api/trim_audio endpoint. You need to provide the audio file URL, the desired length, and optionally a fade duration.

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',
    'desired_length': 30,
    'fade_duration': 2
}
response = requests.post(url, json=data)
print(response.json())
