This proof-of-concept is just waiting for you to put it to good use. [Mike Tsao] wrote an Arduino sketch that lets him decode incoming audio data which could be used to program the device. He&#8217… ...

This arduino audio/music player can amplify and play music from SD card with adding sound effects using your Arduino Board. To play mp3 files using arduino, you need to convert them into .wav files.

Over the summer [ElectroSmash] put the finishing touches on the Arduino Audio Meter, a shield for the Arduino Uno that visualizes various aspects of an incoming audio signal on a set of four 8×8 ...

This project converts an MP3 audio file into a melody that can be played by an Arduino using a buzzer. It processes an MP3 file to extract pitches and durations, then generates Arduino-compatible ...

I suggest that you consult the Wiki. You cant mix the different libraries and if you include the SDFAT library in lib_deps you need to use the corresponding API implementation! I never used the SD ...

The complete circuit diagram for the Arduino Audio Spy Bug transmitter is shown below. If you are completely new to arduino and nrf24l01, you may try this simple Arduino nRF24L01 interfacing tutorial ...

In this arduino based audio meter circuit, analogue input pins of Arduino UNO board are used for measurement of audio-signal levels.

Turn an Arduino Uno R4 into a powerful sound synthesizer and MIDI sequencer! Explore audio synthesis with this Basic Synth project.

Arduino board programmed with an audio file Programmer Mike Tsao has devised a clever method to program an Arduino board using sound.

PICO DSP is another ESP32 development board for audio and digital signage processing (DSP) applications. Equipped with a Wolfson WM9878 stereo audio codec, the breadboard-friendly, Arduino compatible ...
