Using the Trim Audio Endpoint

One of the standout features of FFMPEGAPI.net is its ability to trim audio files through a dedicated endpoint. The 'Trim Audio' endpoint allows you to specify an audio URL, the desired length of the output, and an optional fade-out duration for a smooth audio transition.

  • Endpoint: POST /api/trim_audio
  • Input: Audio URL, Desired Length in seconds, Optional Fade Duration
  • Output: Trimmed audio file ready for download
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}'
import requests

url = 'https://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())

Parameters for Audio Trimming

To successfully use the 'Trim Audio' endpoint, developers need to understand the required parameters:

  • audio_url (string): The URL of the audio file you wish to trim.
  • desired_length (number): The output length in seconds.
  • fade_duration (number, optional): The duration of the fade-out in seconds (default is 0).
