I want to perform a Fourier transform of the raw voice recorded on Alexa for my skill to analyze and formulate a response. Does my skill have access to the raw audio?
That is impossible because of the privacy concerns. The only thing you can get is text from slot values you define or use AMAZON.SearchQuery intent, which has its own limitations, to get what the user tried to search. But audio - no, that is impossible to get inside the skill. But still if you think this is a great features to have, please don't hesitate to add it, or upvote the existing one at amazon uservoice: link
