Hi
Well the Generation loss test was very popular in the days of recording tape for the same reasons. We started doing this at work out of curiosity as much as anything else about 18 years ago.
What we did was use a measurement mic and a 24/96 recorder.
We put the speaker on top of a ladder with the microphone at a meter.
We played a section of music (parts of several tracks edited together) and recorded the mic signal (and in the beginning we also made a gen loss copy of the music track but after 5 generations there was no detectable difference in the direct audio so we stopped that and just did the speakers).
Now days i would skip the MI recorder and get a Motu m2 or other good usb interface and a decent measurement mic. IF you have a set of good headphones, there is something important you can discover too.
They did an interview for a recording magazine at work and some of it was edited into a video that goes into the gen loss test and some on how we hear.
Hope this video makes sense.
