Description. This is a one-chip sound level meter that can be used for displaying the sound level of an amplifier or simply the sound level from a microphone. The heart of the circuit is IC LM 3915 Audio level IC. Even though it is a stand-alone IC, a peak detector based on Transistor BC 558 and diode 1N4001 is also included for better performance.
VU Meter (LM3915) – B2P20 - BnBe Club
https://bitsnblobs.com/vu-meter-lm3915-b2p20/
The LM3915 has an adjustable voltage reference and each of the LEDs represent a 3dB step, this makes it a perfect chip to build a volume unit meter or VU meter. It can only handle one input at a time, so we use two LM3915 ICs to handle both the channels. The audio signal from the Bluetooth receiver is of low amplitude and we use an LM358 op-amp ...

sity or vibration. Audio applications include average or peak level indicators, power meters and RF signal strength meters. Replacing conventional meters with an LED bar graph results in a faster responding, more rugged display with high visibility that retains the ease of interpretation of an analog display. The LM3915 is extremely easy to apply.

VU meter circuit Stereo/Mono 20 LED with PCB. Posted by. By Apichet Garaipoom October 27, 2018 33 Comments. Here are LM3914/LM3915 VU meter circuit projects. They can display with 20 LEDs on stereo, or mono with 10 LEDs for all audio system. Also, we can easily build and cheap. We will be happy when use them.
Audio Level Indicator using LM3914 - VU Meter
https://circuits-diy.com/audio-level-indicator-using-lm3914-vu-meter/
Circuit Diagram Explanation. In this Audio Level Indicator using LM3914, we provide the audio input at the signal input pin of an IC. The IC can work into different modes, the dot mode, and the bar graph mode. In DOT mode only one LED glows depending on the input and for this pin 9 remains open.
