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. Students would first describe what they hear before looking at any visual representation. I found [url=https://sunofixer.top]mp3 to spectrogram[/url] 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. My worksheet would have separate spaces for listening notes, format settings, and unresolved questions. I would assess the quality of the explanation instead of asking students to improve the audio. 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?
