before starting contribs in this forum I would like to introduce myself:
My name is Gerhard, I am living in Germany and until my retirement I was working as an automotive electronics engineer. My hobbies are chess, motorcycle, electronic and... yes, Audio (esp. amps & loudspeaker).
My long-lasting back-brain audio-project surrounds the topic "Current-Drive for Loudspeaker (I-Drive vs. V-Drive). I intend to simulate characteristic params like THD, IMD, Step-Response, Bursts, etc. using tools like Matlab and Spice. All this with real loudspeaker loads.
Linear loudspeaker models are available and producing reasonable results.
Currently I am working on analysing methods and algorithms.
The benchmark shall include <10 linear amplifiers, which requires available schematics in gEda, KiCad or Eagle, to support netlist creation for Spice-simulations with "real loads".
The simulations will be restricted to the linear travel of the loudspeaker-cone. Extended nonlinear simulation can start later.
Are there already any contribution along this topic or is this a new question?
I don't want to re-invent the wheel.
Where should this project be issued within this forum's scope?
looking forward to your response...
