Guitar/Music effect box for an ESP32 with I2S audio output.
This is a simple guitar effect box built upon the ESP32 using its internal 12bit ADC and sending audio out through I2S. The pins used for I2S is BCLK = GPIO26, WS = GPIO25 and DATA = GPIO27. The analog input, if connecting from a passive instrument, will require some pre-amplifier with a gain about 20dB.
数字音频接口之I2S总线协议详解 - CSDN博客
2024年6月4日 · I2S(Inter -IC Sound)是一种广泛应用于数字音频传输的串行接口标准。 它最初由飞利浦(Philips)公司开发,用于解决在 集成电路 之间传输音频数据的问题。 I2S协议定义了音频数据的传输格式、时序和控制信号。 在工作中音频采集和输出,AD和主芯片之间的通信均是通过I2S进行通信的,其应用场景如下: I2S RX方向:麦克风在机械振动下将声音信号转变为电压信号,电压信号经过放大等处理,给到ADC采样,将模拟信号转化为数字信号;音频在ADC …

I2S DAC output , realtime audio possible - Raspberry Pi Forums
2023年4月8日 · hello forum, i want to build an E-Guitar-effect-Pedal with the raspberry pi zero w 1.1 involving DSP (probably using rtaudio API,DSP library's) i thought it this way : E-guitar -> preamp -> I2S ADC (input) -> rpi (doing DSP stuff) -> I2S DAC (output)
FPGA Based Electric Guitar Effects Pedal : r/FPGA - Reddit
2022年2月2日 · I've successfully accomplished hearing the guitar sound coming out of the I2S2 PMOD into my speakers, using an example code I've found for an I2S transceiver. I'm wondering what would be the correct way (VHDL-wise) to create the effects (DSP) on the data.
A real-time digital guitar tuner with ESP32 Microcontroller and I2S ...
This repository contains an implementation of an audio processing system using I2S and FFT on an ESP32 microcontroller. The project reads audio data through an I2S microphone, performs Fast Fourier Transform (FFT) to detect the dominant frequency, and identifies musical notes based on the detected frequencies.
