Meter Counter Circuits
Sounds are picked up by MIC1 and fed to the input of the first op amp. The signal is then fed to the input of second op amp Ulb, where it is boosted again by a factor of between 1 and 33, depending upon the setting of range switch Sl. With the range switch set in the A position, R6 is 1 K!:J and R7 is 33 K!:J, so that stage has a gain of 33.
This circuit compares a rectified input, f."!N, with a voltage that decays exponentially across a 4. 7-KO resistor and a Â·o.Ol-I"F capacitor. Comparing the exponentially decaying voltage with the rectified input provides a peak-level indication that requires no adjustment.

The 1K resistors in the circuit are essential so that the LED`s turn on at different audio levels. This circuit is easily expandable with more op-amps, and is not limited to use with the LM324. The 33K resistor on the schematic is to keep the signal input to the circuit at a low level. The circuit in it`s current form will accept line level inputs

LED VU Meter with LM3914N
The circuit is based on an LM3914N bar graph display driver device (IC1), which can be used to drive up to ten LEDs. This is connected so that with OV12 at the input only the first LED indicator switches on. This simple peak reading VU meter circuit uses six LEDs to indi-cate six signal levels at 14, 8, 3, 0, +3, and +6dB, or any other levels having the same..

If you are making a stereo amplifier, or if you own one already, then do not hesitate to add this circuit. The entire circuit is wired around IC4017 whose clock input is tapped through transistor BC107. Basically, IC 4017 is a 1-of-10 decade counter or a decoder. To suggest the design, this circuit fills the gap between a simple 1-transistor sound
