Understanding the Trim Audio Endpoint

The Trim Audio endpoint allows you to trim an audio file to a specific length while offering optional fade-out effects. This is particularly useful for creating clips or segments of longer audio files.

By sending a POST request to the /api/trim_audio endpoint, you can efficiently trim any audio file hosted online.

  • Endpoint: /api/trim_audio
  • Method: POST
  • Content Type: application/json or form data
  • Parameters: audio_url, desired_length, fade_duration
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 Required for the Trim Audio Request

To successfully use the Trim Audio endpoint, you must provide specific parameters in your request. The audio_url and desired_length are mandatory, while the fade_duration is optional.

Here's a breakdown of the parameters required:

  • audio_url: The URL of the audio file to be trimmed (string, required).
  • desired_length: The desired output length in seconds (number, required).
  • fade_duration: Optional fade-out duration in seconds (number, optional, default is 0).
