How does the WebFaz audio extractor work?

The extractor separates the sound of a video and creates an audio file for you to listen to, share or use in other work, without changing the original video.

1. Select the video. Drag the file to the marked area or click to choose it. Use the player to check the content and find the part you want to use.

2. Choose everything or a clip. To extract only a part, turn on “Trim clip” and fill in the start and end in hours:minutes:seconds. Leave trimming off to use all the audio.

3. Set the output. Choose the format, the available quality and the audio channels. If the sound is low, try the volume gain; larger increases can distort a recording that is already loud.

4. Extract and listen. Click “Extract audio”, wait and check the result in the player. Use “Download audio” to save it. The video must contain an audio track.

About Audio Extractor

Pulls the audio track out of a video and saves it as a sound file, useful for podcasts, classes and music.

A practical example

You recorded a 1-hour class on video and want to listen to it on the bus. You upload the video, choose MP3 and extract. You listen to a preview to check it and download the audio, which takes a fraction of the video’s size and plays on any device.

How to use it

  1. Select the video.
  2. Choose the audio format.
  3. Extract and listen to the preview.
  4. Download the file.

Limits and cautions

  • Audio can only be extracted if the video has a sound track.
  • Very heavy videos depend on the device’s memory.

When to use it

  • Turning a class, lecture or interview recorded on video into audio to listen to later.
  • Extracting the soundtrack or speech from your own video to edit in another program.
  • Preparing the audio of a recorded meeting to be transcribed.

Tips

  • For speech, MP3 or M4A at medium quality is enough and the file stays small.
  • For professional editing, extract to WAV or FLAC so you do not lose quality.
  • Respect copyright: extract only audio you have the right to use.

What happens in your browser

The video is read in the browser and the audio track is separated and saved to a new file. The audio is saved in the format you choose and, if you like, only for the clip you define with the trim (start and end).

Lossless formats (WAV and FLAC) preserve the track’s quality, with bigger files. Lossy formats (MP3, AAC) produce much smaller files, with compression that is usually imperceptible in speech.

The processing uses the device’s memory. Very long or heavy videos can take longer or run out of memory on simple phones.
