How do I access my audio?

You need to be recording raw audio in order to be able to play it back. The audio that we record by default is encoded as mel frequency cepstral coefficients (MFCCs) and can't be played. We don't turn raw audio on by default because we want users to make a conscious decision to turn the raw audio on for privacy reasons. If you want to record, you need to go to the Settings tab in the app and hit the raw audio switch.
