Hi, I’m Franz. Welcome to my site!
You might (at some point) find here some notes on control theory, acoustics, signal processing, machine learning, meditation, the good life, and other fun things.
Enjoy!
| Date | Note | Abstract |
|---|---|---|
| Feb 27, 2025 | Sounddevice callbacks without Python interpreter | Numba compiles Python functions to machine code. A C function-pointer to that machine code can be passed directly to PortAudio as callback. This enables real-time audio processing without the Python interpreter in the callback loop. |
| Oct 7, 2024 | On sound field control problems in time-domain | Don’t solve them in frequency domain. |
| Feb 9, 2023 | On the choice of output in model reference control | This note discusses the choice of the output function when input-output linearizing. |
| Jan 15, 2023 | Mantras of Loving-Kindness | |
| Nov 25, 2022 | Model Reference Control | This note derives the feedback control law for a nonlinear control-affine system that tracks the output of a linear reference system. This is the basis of linearizing loudspeaker drivers. |
