Audacity is a free audio editor and recorder for interviews, spoken assignments and student podcasts. Recording, editing and exporting sound give it a clear purpose when a course asks you to submit audio.
It outranks #9 for a focused audio task because video scenes add unnecessary choices. We put it below #7: arranging a PDF is more broadly useful across coursework. Record a short sample before an interview, then listen for clarity. It is an audio tool, so choose OBS Studio when the assignment needs video.
