Well in audacity if you hit ctrl+P then you get the preferances menu, and you should be able to make the recording device your output. That is, it will record what you hear. Then you hit the red circle to record, and run the aquaria mod. Make sure that on the main menu you mute music and sound effects so that you wont get crossovers as the mod loads. Then when the voice clip finnishes, close aquaria and hit the stop (square) button on audacity. Now you should have the whole thing recorded, and you can select bits of the recording and hit delete to remove them (bits such as the silence as aquaria loaded, the menu song of aquaria etc.)
Or if you ask me nicely then I suppose I could send you mine, but its really not that hard to do and I did cut out bits of where Eric talks about Naija.
