simpledsp

Simple DSP functions.

Overview

Functions for DSP, mostly targeting real time application.

Implemented

• FFT (radix2 / radix4)
• IIR (cascaded 2nd order)

TODO

• Documentation
• IIR band stop filter type
• FIR filter
• Others

Notes

• FFT coefficients are computed at compile time thanks to gcc extensions.

Required to build tests

• Conan2
• CMake
