How to extract sound from movie

This becomes particularly handy when you have a slow internet connection. But we always appreciate it as it is easier to handle with small files. First of all download and install Pazera Free Audio Extractor. It has no fancy design, but its simple and easy to use. Just follow these few steps:

  1. Drag and drop your movie into the program window
  2. Set the output format to WAV
  3. Set the channels to mono
  4. Click on the CONVERT button

The program will extract audio from your clip and save it to the file with the same name as your video file, but with the WAV extension.

TIP: Save these encoder settings as 'yellowhammer dialects' for future use. It will save you some time.
