How to Trim Audio with FFMPEGAPI.net

This is particularly useful when you need to prepare audio clips for apps or presentations that require audio playback of specific durations.

  • POST method to send requests
  • Supports audio URLs in various formats
  • Customizable output with optional fade-out effects
import requests

url = 'https://ffmpegapi.net/api/trim_audio'
data = {
    'audio_url': 'https://example.com/song.mp3',
    'desired_length': 30,
    'fade_duration': 2
}
headers = {'Authorization': 'Bearer YOUR_API_KEY'}

response = requests.post(url, json=data, headers=headers)
print(response.json())
curl -X POST https://ffmpegapi.net/api/trim_audio \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer YOUR_API_KEY' \
-d '{"audio_url": "https://example.com/song.mp3", "desired_length": 30, "fade_duration": 2}'
