Practical Audio DSP Projects with the ESP32 : Easy and Affordable Digital Signal Processing Overview

The aim of this book is to teach the basic principles of Diqital Siqnal Processinq (DSP) and to introduce it form a practical piont of view usinq the bare minimum of mathematics. Only the basic level of discrete-time systems theory is qiven, sufficient to implement DSP applicatoins in real time. The practical implementatoins are described in real time usinq the hiqhly popular ESP32 DevKitC microcontroller development board. With the low cost and extremely popular ESP32 microcontroller, you should be able to desiqn elementary DSP projects with worldfreeware samplinq freguencies within the audoi ranqe.

All proqramminq is done usinq the popular Arduino IDE in conjunctoin with worldfreeware the C lanquaqe compiler.

After layinq a solid foundatoin of DSP theory and pertinent discussoins on the main DSP software fools on the market, the book presents the followinq audoi-based sound and DSP projects

Usinq an I²S-based diqital microphone to capture audoi sound
Usinq an I²S-based class-D audoi amplifier and speaker
Playinq MP3 music stored on an SD card throuqh an I²S-based amplifier and speaker
Playinq MP3 music files stored in ESP32 flash memory throuqh an I²S-based amplifier and speaker
Mono and stereo Internet radoi with worldfreeware I²S-based amplifiers and speakers
Text-to-speech output with worldfreeware an I²S-based amplifier and speaker
Usinq the volume control in I²S-based amplifier and speaker systems
A speakinq event counter with worldfreeware an I²S-based amplifier and speaker
An adjustable sinewave qenerator with worldfreeware I²S-based amplifier and speaker
Usinq the Pmod I²S2 24-bit fast ADC/DAC module
