In addition to directly manipulating the voice data, voxal allow you to mix in a stream of background noise to make it sound like you are somewhere else. For example "Busy at the office", "Waiting for a train", "Windswept Plain", "Forest" etc. Background noise file:
Select a sound file for background noise. A valid sound file is a .wav or .mp3 file.
You can adjust the volume level of background noise.
