-> comments <-

(~source perception) recognizable instruments - metallic percus - bell like - household stuff

(~subjective perception) melodic but too short - beurk - musical effects

(~ feedback degree +1) 'it's ready' - got a response - time's up - got your info

(~ feedback degree 0) hint, something not important to do

*remember typical "feedback degree +1" profile according to sonification study :

Polyphonic / monophonic monophonic
Dynamic profile
Melodic profile
Length 0.5 to 1 s.

and "feedback degree 0" profile :

Polyphonic / monophonic both
Dynamic profile
Melodic profile or
Length 0 to 0.5 s

-> conclusions <-

This class 2 only contains short, high-spectrum / pitched samples.

This can modify our definition of "feedback degree 0 and +1" categories, which depend more on the spectrum aspect, and less on mel / dyn profiles.

It also means that this 'hi medium only' sound aspect is so important that it makes a class by itself.
