Hi
the papers on http://www.klippel.de/pubs/papers.asp where quiet
interesting. But the page went down.
It looks like it went to:

By the way it is kind of sad that everyone (including me) always uses

Hi Mathieu -
again, sorry for the big delay. I was a bit busy the past 2 weeks.

I agree with Martin Peach in most points and want to add some sentences.

Sorry for answering this late. And I was wrong in my last mail. The
signal doesn't have to be differentiated but integrated (like you
already did in your first post).?
The signal in pd represents the current flowing through the speaker's
coil (if we assume it isn't capacitive or inducti

Hi!
I'm no speaker modeling expert at all, but I can try to describe what
produces sounds in an overloaded speaker. There are various sources of
distortion, symmetrical (mechanic suspension) and asymmetrical (magnetic

Thank you for your answer,
but as I wrote I don't want the sound of simple clipping like clip~,
tanh~ or overdrive~. I want the sound of a speaker crying for mercy
because you put just too much through it.
But I don't know where to start. I know there are complex distortion
effects, which are able
Hi,
does anyone know how to simulate the sound of an overdriven speaker? You
know the crunchy sound when you torture it with a strong bass. It's
nowhere near the sound of an normal overdrive with some kind of clipping.
