For an introductory audio lesson I want students to compare several exports of one short passage. A generated instrumental could provide the example provided students can always return to the original file. I would start with listening notes so that the image does not dictate their initial observations. I found mp3 to spectrogram as a possible reference while planning the visual part. For the comparison I would keep the chosen passage fixed and check playback levels carefully. The lesson needs to distinguish an observation in the image from a claim about its cause. I am considering a worksheet that records what was heard how it was exported and remaining uncertainties. There would be no requirement to repair the clip or produce a supposedly perfect version. Students would record the software used for each export so that their comparison can be repeated later. What simple controls would make this exercise understandable for a beginner class?
