[music-dsp] testsignals for nonlinear system identification

[Georg Holzmann]

Hallo!

I am searching for good testsignals to identify nonlinear audio systems 
(like tubes, distorsion effects, ...) with volterra/wiener systems and 
neural networks.
So far I tried bursts of noise and also bursts of sines, but they don't 
always work as I want when using the identified system afterwards with 
general audio signals ...

I have found the following DAFX papers about that topic:
"A Measurement Technique for Highly Nonlinear Transfer Functions" 
(Möller, Gromowski, Zölzer)
and
"Discrete-Time Models for Nonlinear Audio Systems"
(Schattschneider, Zölzer)
where they used noise and sine bursts.

Are there any other resources which signals to use for nonlinear system 
identification or does anyone want to share some practical knowledge ?

Many thanks for any hints,
LG
Georg
