That tis gud. Vely vely gud.
it do really sounded her.. but u should add like you know an echo.. or something to make the audio far away.. cuz you know that in the game portal.. GlaDoS use stereo.. not headphones to wear for the player.. like an what do you call this.. like a surround sound or something..
Don't you mean make it sound like she's actually in the end chamber in Portal?
Please contact me if you would like to use this in a project. We can discuss the details.
