<p>[QUOTE=&quot;ChloeDaw, post: 161763, member: 54472&quot;]Has anyone taught a practical lesson that compares lossless audio with compressed versions of the same source? I plan to use a short generated instrumental and keep its original export available to everyone. The first task would ask students to write listening notes before opening a visual display. I found <a href="https://sunofixer.top" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://sunofixer.top" rel="nofollow">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. Students should not assume that a difference in the display proves a problem with the source. 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. How would you keep this lesson manageable for students learning audio formats for the first time?[/QUOTE]</p><p><br /></p>
