Using the Extract Audio as MP3 Endpoint

The Extract Audio as MP3 endpoint allows you to efficiently extract audio from a given video URL. This can be particularly useful for scenarios where you need to create audio files for podcasts, soundtracks, or other audio-focused applications.

  • Endpoint: POST /api/extract_audio_mp3
  • Returns an MP3 audio file from a video URL.
  • Supports customizable MP3 bitrates.
curl -X POST https://ffmpegapi.net/api/extract_audio_mp3 \
-H 'Content-Type: application/json' \
-d '{"video_url": "https://example.com/video.mp4", "bitrate": "192k"}'
import requests\n\nurl = 'https://ffmpegapi.net/api/extract_audio_mp3'\ndata = {'video_url': 'https://example.com/video.mp4', 'bitrate': '192k'}\n\nresponse = requests.post(url, json=data)\n\nprint(response.json())

Configurable Parameters for Audio Extraction

When using the Extract Audio as MP3 endpoint, you can specify two parameters: the video URL and the desired bitrate for the MP3 file. This flexibility allows you to tailor the audio extraction to fit your project's needs.

  • video_url: The URL of the video you want to extract audio from (required).
  • bitrate: The desired bitrate for the MP3 file (optional, default is 192k). Available options: 96k, 128k, 192k, 256k, or 320k.

FFMPEGAPI.net simplifies the process of automating video editing tasks, especially audio extraction.
