STM32F769i DISCO Part 8 - Audio Filtering - Object (C++) instantiation and use - Tutorial

In this video I present the development of a filter class on the STM32F769 DISCO development board. The filter is implemented in C++, using a Canonical filter structure (2nd Order BiQuad). I calculate the filter coefficients based on the excellent DAFX book (ISBN: 978-0-470-66599-2) and explain how this integrates into the audio system using FreeRTOS. Using this method, you can easily change the filter coefficients to suit different filter types, for example, shelving, LPF etc.
