Has anyone taught a practical lesson that compares lossless audio with compressed versions of the same source? The source would be a short generated instrumental, with the original retained throughout the exercise. The first task would ask students to write listening notes before opening a visual display. I found <a href=https://sunofixer.top>mp3 to spectrogram</a> as a possible reference while planning the visual part. We would then compare documented export settings using the same passage and a consistent playback level. 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?
