In this project, I use an Arduino UNO to record audio, that can be used for Speech Recognition purposes, with a MAX4466 Electret Microphone Amplifier. This is a fully assembled and tested board, that ...

The Arduino Mini Amplifier is a complete, open-source audio amplifier system that combines vintage analog audio processing with modern embedded control. It features Bluetooth and line-in audio inputs, ...

Thanks to software frameworks and libraries that have become quite powerful over time, even with a compact and inexpensive system, it is possible to achieve complex functions. In this project, we use ...

In the first part of this audio synthesis series, we explored the block diagram and key functions of the Basic Synth software. In this concluding installment about the MiniPhonic, we turn our ...

The MAX4466 microphone amplifier module is a very versatile and easy-to-use microphone amplifier module. As the name suggests it is based on the MAX4466 amplifier chip from Analog Devices. It offers a ...

We’ve all been there: after assessing a problem and thinking about a solution, we immediately rush to pursue the first that comes to mind, only to later find that there was a vastly simpler ...

The project is an experiment to illustrate that an Arduino can be used to create a real-time audio processing wherein the first set of examples alter an incoming audio signal to an audio output and ...

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 ...
