    I have to workout how much data is used to record an audio sample. simple enough stuff

    Just wondering it underlines that the type of audio being recorded is stereo. wondering does stereo use more data as i have read there is a richer sound caused by over lapping frequencies.

    Well it depends on the quality of the audio as well.

    If you for example have 128bit compressed audio in a mono format it's single channel audio compressed to a 128bit ratio. That will be smaller than a 128bit compressed stereo stream as it has more channels (usually 2) of audio. The difference between mono and stereo is that mono is single channel audio sent to multiple speakers so each speaker plays the exact same audio at the same time. Stereo is multiple channels sending differential steams to different speakers. So channel 1 goes to speaker 1 and channel 2 goes to speaker 2, at it's simplest explanation.
