Simple Surround Sound Decoder
This surround-sound decoder is based on the "Hafler" principle, first discovered by David Hafler sometime in the early 1970s. The original idea was to connect a pair of speakers as shown in Figure 1, for use as the rear speakers...
Delayed Power supply schematic
I had designed up an oscillator with a Power Output circuit. Problem was when power was applied to the entire circuit, the output of the Oscillator gave a Momentary Spike into the output circuit. Thus Driving it full on for...
surround sound processor circuit
This is an easy-to-build surround sound processor circuit utilizing the digital delay processing method. This audio processor does not employ any specialized function integrated circuits that are difficult to obtain, and it is designed using only common-purpose integrated circuits. This...
Arduino Vocal Effects Box
This Arduino-powered vocal effects box pitch shifts and distorts incoming audio signals to produce a wide variety of vocal effects. This project is an experiment with real-time digital signal processing using Arduino. It samples an incoming microphone signal at a...
IC Voltage Regulators-withCircuit - Design & Theory
IC Voltage Regulators - Circuit diagram and block diagram of linear, fixed, adjustable (positive and negative), and switching voltage regulators.
IC voltage regulators are essential components in electronic circuits, providing stable output voltages from a varying input voltage source. They can...
simple delay speaker circuit schematic
This circuit was designed for an audio amplifier project to control the speaker output relay. The primary function of this circuit is to manage the relay that activates the speaker output in the audio amplifier. The circuit introduces a delay...
Home-made high-performance four-dimensional surround sound amplifier circuit
The surround processing section C1891A is a product from Sony Corporation of Japan that features a four-dimensional home theater surround processing circuit. It includes a parent roll phase-shifting circuit and a matrix surround sound amplifier. Additionally, it provides three types...
audio surround decoder circuit diagram
The circuit operation begins by transmitting stereo surround sound signal quality information through the master volume circuit. This drives the left channel connected to the LCH Model TL072 IC1A and IC1B, which are linked to the right channel (Rch). The...
ARRL Handbook Audio Intelligibility Enhancer
Assistance is sought for building the N4GG audio intelligibility enhancer project as detailed in the ARRL Handbook. A circuit board has been ordered from Far Circuits, but there are difficulties in sourcing the necessary components. Attempts have been made to...
