I see. It is the first time I visited your web site.
So, you have set the "Absolute Reference" for samples of distortion of midi
sound.

As I have mentioned sometime ago in the HKRAV, only the person who site on
the same location of the microphone of single pick-up recording, or
electrical music (tone) came give "reference" of the recording.

So, what's the "absolute reference" for audience to quantify  "audible
distortion" in case of CD musical software ?

So, there is significant individual variation of the thresholds of
audiblity.

So, you are measuring  "distortion" of a gear, e.g. CD player, by gears in
an environment which have distortion already.

After all, we are "enjoying" gear rather than "measuring" the gear.
