adding vu meter to your computer
A VU meter from a SONY double tape deck, model number "SONY TC-W230," has been salvaged and is intended to be integrated into a computer tower case. The process begins with identifying the connections on the printed circuit board, specifically...
Peak-Reading VU Meters
Peak reading meters, popular in Europe for years, are just now coming into greater favor in America, and for good reason. The main purpose for having a VU meter is obviously to monitor signal levels going to a tape recorder,...
Electronic VU Meter
A portable CD player, radio, cassette player, a couple of microphones, and a PC sound card are connected to the inputs of an audio mixer. The output of the mixer is connected to a pair of active loudspeakers. The objective...
vu meter circuit
This is the simplest VU meter that can be constructed. It is based on a single integrated circuit. A volume unit (VU) meter, or standard volume indicator, is a device used to display the level of any voltage signal source,...
Adding VU Meter to Dantimax thatmic preamp
A user has recently purchased the Dantimax that mic preamp and is seeking guidance on how to install a VU meter.

vu meter using lm3915
This is Version 1 of the VU meter that has been planned for construction. The final version will differ from the current one as its performance did not meet the requirements. This version cost approximately 100. The IC LM3915 was...
Stereo VU Meter Circuit LM3915 IC
The function of the sound level display circuit is to enhance the appearance of an amplifier circuit or a radio player. It provides an impressive visual representation of audio levels.
The sound level display circuit serves as a visual indicator of...
LED display control circuit diagram of a counter
The decimal seven-segment storage decoding drive unit 74HC143 provides a constant output for all segments, each at a voltage of 5V and a current ranging from approximately 15mA to 22mA. The BCD data for the seven-segment decoder can be accessed...
LED bar peak program meter display for audio
A vertical column of LEDs is configured so that as the audio signal level rises, an increasing number of LEDs illuminate. The LEDs are arranged in increments of 6 dB. The circuit features a fast response time and a one-second...
