When an audio file is imported into Wwise, the original high-quality file is saved within the Wwise project. When converting the files into a specified format, Wwise then creates a new converted file for each original audio file. While working in Wwise, you can switch between listening to the original or converted file in the Transport Control by toggling the Original button. This feature is convenient for rapidly assessing if the applied conversion settings are adequate.

Let’s compare the EvilHead_Attack_Charge converted sound with its original.

	If you can’t hear the converted file and the Play button is grayed out, it means the audio file has not been converted yet. You will also notice that the container name in the Project Explorer is displayed in Blue instead of white, indicating that the audio file has not been converted yet.

What you’ll hear now is the converted audio file. When converting audio sources, the new files might not sound identical to the original due to audio compression, effects, or other modifications to the audio source. So, if you’re listening to and modifying the original, you might experience a vastly different result in game. Good practice is to keep the Original toggle disabled throughout most development because you will then hear how the audio source will sound inside the game.
