Recording Your Lectures

Lectures which are scripted will be more concise, precise, and accurate than lectures recorded during a live class.  Also, scripted lectures will be shorter (since the pauses are eliminated -- which normally take place in the classroom to allow students to finish writing, to ask questions, and to provide answers to your questions).

Scripting your lectures also helps you meet accessibility requirements; your script becomes your text-transcript for your audio file.

You should consider using a headset microphone.  Place the microphone above your nose to help eliminate breath noises from the recording.

You can record to your computer or to a portable voice recorder.  Your headset can plug into the voice recorder to allow you to record your materials in environments where computers are not available.
