In this article I have explained using circuit diagrams how a clipper and a compressor circuits work to processes an input audio signal as per the required output signal. What is an Audio Clipper An audio clipper circuit is basically used to alter or restrict the amplitude (volume) of an audio signal. There are mostly […]

Audio Amplifier Circuit using IC L165
The discussed audio amplifier circuits are designed around the versatile L165V amplifier IC, which is quite adaptable in various scenarios. Working Voltage Range While the minimum recommended supply voltage is 12V, the L165 amplifier circuits show satisfactory operation even below 9V, albeit with somewhat reduced performance. On the upper end, the absolute maximum supply voltage […]
Guitar Jammer Circuit (Mix an External Audio with your Guitar)
This Guitar Jammer circuit I have explained below enables you to jam out to your favorite songs from your cellphone or computer. You can mix an external audio track with your guitar sound, then use headphones to listen to the blended result. Imagine playing note-for-note copies of legendary guitarist’s riffs and exchanging scorching pentatonics, “hammer-ons,” […]
Audio Dithering Circuit for Enhanced Crisper Music
In this article I have explained a simple circuit concept which can be used to transform an ordinary analogue audio signal into a much vibrant and crisper digital music, by adding an external random noise to the audio, which is also known as pink noise. Video dithering is a procedure for generating an image file […]
Audio Delay Line Circuit – For Echo, Reverb Effects
An audio delay line is a technique in which a given audio signal is passed through a series of digital storage stages, until the final audio output is delayed by a certain period (usually in milliseconds). When this delayed audio output is fed back to the original audio, it results in an amazingly enhanced audio, […]
Simple Mini Audio Amplifier Circuits
In this article we are discussing a handful of simple, mini audio amplifier circuits which can be built quickly for amplifying very tiny input signals into audible speaker outputs. 1) 1 Watt Amplifier Circuit The first simple mini audio amplifier circuit works with a ‘complementary’ output stage, having a single NPN and a single PNP […]
