If you have a learning contract which allows you to make audio recordings, you have permission to record any of your lectures, seminars or tutorials using your own equipment. This is allowed on condition that the recording is solely for your own use. The rights belong to the University and the lecturer concerned, it must not be shared, published or otherwise made available to others for any reasons whatsoever.
Should academic staff wish to allow any other student to record their lecture for personal use, then they are free to do so; but there is no obligation to do so in any case other than those authorised by their learning contract. Students without a learning contract must request permission to make an audio recording from the relevant academic member of staff prior to the lecture taking place. Misuse of recording could potentially lead to action under the disciplinary procedure.
