“In this project I will solve one of the biggest problems I have with modern movies. The problem is that the conversation volume is way too low in comparison to the music volume. That is why I combined an Arduino …
“An Ambisonic Microphone records audio in multiple directions allowing you to change the direction of where you are listening after recording, sometimes while you are listening. There are several of these on the market but we are going to build …
“This is a complete microphone signal conditioning project. Designed primarily for voice-band applications, this project provides amplification, limiting, variable compression, and noise gate. User-adjustable compression ratio, noise gate threshold, and two different fixed gains optimize circuit operation for a variety …
“Good afternoon, dear viewers and readers. In todays article, I will show you the universal microphone amplifier based on the microcircuit NE5532. The microphone amplifier schematic diagram and printed circuit board (PCB) were developed in Easy EDA online environment. The …
“In this project we will keep it simple when it comes to wireless audio communication. Instead of trying to use an nRF24 or RF modules, we will go back to the old days in which they used AM radios. I …
“This guide will walk you through creating a USB microphone on the Raspberry Pi Pico using the RP2040’s PIO, DMA, and USB capabilities. Introduction This guide will walk through how to create your own USB microphone device using a …
“This product alerts the user when they are speaking too loudly via two LEDs. Louder voices spread more viral particles, so quieter is safer. In this pandemic it is important to take reasonable measures to reduce spreading viruses. A paper …
“The TinyML Wake Word demo on the Raspberry Pi Pico. A less than $10 wake word! TinyML Wake-Word Detection on Raspberry Pi Pico This application implements the wake word example from Tensorflow Lite for Microcontrollers on the Raspberry Pi Pico …
“I was desperate for something to read during lockdown and found in my bookcase an IEEE report on Speech Recognition from the late 1970s. Could an Arduino Nano do the same as a computer from that era? How does a …
“Random numbers are often used in daily for example in encryption, gambling, gaming and much more. These numbers are generated by computers using complex algorithm but it can be predicated if we know the seed value and the algorithm. So …
