Ahmet Ibrahim og Dogan Ibrahim Practical Audio DSP Projects with the ESP32

Produktbeskrivelse

The aim of this book is to teach the basic principles of Digital Signal Processing (DSP) and to introduce it from a practical point of view using the bare minimum of mathematics. Only the basic level of discrete-time systems theory is given, sufficient to implement DSPapplications in real time. The practical implementations are described in real time using the highly popular ESP32DevKitC microcontroller development board. With the low cost and extremely popular ESP32microcontroller, you should be able to design elementary DSPprojects with sampling frequencies within the audio range. All programming is done using the popular ArduinoIDE in conjunction with the Clanguage compiler. After laying a solid foundation of DSPtheory and pertinent discussions on the main DSPsoftware tools on the market, the book presents the following audio-based sound and DSPprojects: Using an I²S-based digital microphone to capture audio sound Using an I²S-based class-D audio amplifier and speaker Playing MP3 music stored on an SDcard through an I²S-based amplifier and speaker Playing MP3 music files stored in ESP32 flash memory through an I²S-based amplifier and speaker Mono and stereo Internet radio with I²S-based amplifiers and speakers Text-to-speech output with an I²S-based amplifier and speaker Using the volume control in I²S-based amplifier and speaker systems A speaking event counter with an I²S-based amplifier and speaker An adjustable sinewave generator with I²S-based amplifier and speaker Using the Pmod I²S2 24-bit fast ADC/DAC module Digital low-pass and band-pass real-time FIR filter design with external and internal A/D and D/A conversion Digital low-pass and band-pass real-time IIR filter design with external and internal A/D and D/A conversion Fast Fourier Transforms (FFT)...
