Realistic sound

The "mail in" category belongs to the "feedback degree +1" category - here is the corresponding typical profile :

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

-> conclusions <-

The samples that were put in the "mail in" globally correspond to the "feedback degree +1" profile when the following criteria are considered :
* length 0.5 to 1s., monophonic
And they don't correspond to this profile when following the following criterium :
* melodic profile that is downhill here instead of uphill for the FB+1 profile

The difference concerning the melodic profile can be understood : a mail out is intuitively related to something going out, or upwards - as can be seen for the mail out prototype that sounds like something being thrown in the air, and a mail in is related to something coming to the user, coming downwards.

Concerning our category classification system, it can leads to the following conclusion :
For the moment, we have only categories, without making any sub-categories. It would be interesting to make sub categories - in this case, in mail is a sub category of FB degree +1.

Our sub category "mail in" would have the following profile :

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