I am preparing a classroom exercise about what changes when an audio file is exported into different formats. A generated instrumental could provide the example, provided students can always return to the original file. The first task would ask students to write listening notes before opening a visual display. I found mp3 to spectrogram as a possible reference while planning the visual part. The next step would compare export settings while keeping the passage and playback level consistent. 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. The task would end with a comparison rather than a demand to fix the example. Students would record the software used for each export so that their comparison can be repeated later. Which comparison mistakes should I explain before students begin this exercise? |
