Consider a conductor organizing the instruments in an orchestra. In a speaker system a passive crossover network functions similarly to that conductor but for sound. Like small speakers regular speakers are made up of several pieces each of which is designed to handle a particular tone. Woofers provide deep booming sounds, tweeters produce high squeaky […]

Simple Audio Mixer Circuit using a Single Transistor
The construction of a simple circuit which mixes two sounds is explained in this article. This device uses a single transistor and a tiny switch for mixing two different sounds into one much like a little DJ mixer. This project is an excellent way to learn how to use electronics for blending sounds. Circuit Working: […]
Simple Echo Effect Generator Circuit
How to build a circuit that produces an echo effect in music is explained in this post! Because they provide a feeling that music echoes across a vast area so transistors such as the BC547 are used. What is an Echo Effect Generator Circuit: To create an audible echo effect in audio signals an electrical […]
Simple Noise Limiter Circuit
Ever try to listen to the radio but there is a static noise making it hard to hear? This post shows how to build a circuit that can reduce that noise and make the radio signal clearer. This circuit uses transistors like tiny switches to filter out the unwanted noise. WARNING: Building electronics projects can […]
