Phase Shifting with DSP using the Teensy

In this video I do some DSP Phase shift processing with the Teensy 4.0. Some other DSP videos I have: STM32 DSP:    • DSP with Nucleo 144 F767 - Part 1   ESP32 DSP:    • ESP32 IoT Radio - Part 2 Audio Processing   Big shout out to Charlie Morris' channel for all the inspiration. Lots of great stuff on his channel    / @charliemorriszl2ctm   The Teensy and the Audio Shield https://www.pjrc.com/store/teensy40.html https://www.pjrc.com/store/teensy3_au... Correction: I meant to say "I2S" not I2C Here's the Iowa Hills software site http://www.iowahills.com/ I am using the Hilbert Filter from this page http://www.iowahills.com/8DownloadPag... Note I missed out a critical parameter in the Hilbert filter configuration and that is you have to put in the desired phase offset in the "Phase Add" field (i.e. +45 and -45) Here's some DSP theory pages.
