ESP32 Arduino with arduino audio tools

Описание

Update: I mentioned that I have been unable to find a replacement for the Iowa Hills FIlter software. Since creating this video I was able to solve that problem. See here

In this video I will be playing around with some of the audio processing capabilities of the arduino-audio-tools toolkit using an ESP32. It does assume you have the ESP32 set up in Arduino. If not go here:
https://docs.espressif.com/projects/arduino-esp32/en/latest/getting_started.html

Here's the Audio Library

Here's my modified examples including a doc that shows the pin connections to the pMod

Here's the pMod I2S2 Codec (no affliliation)

Here's the eariler video I did on deriving the coefficients

The IOWA hills walkthrough starts at around 9:30. See this video for a replacement method

Here's the ESP32 I was using (no affiliation)
