Analog Vu Meter Drivers For Mac

Not sure if this is the correct subforum, so an admin feel free to move the topic if its in the wrong place. I will keep updating this post until the project is finished.

Project: VU Meter Brief: Large LED-lit system that can have stereo sound input and output corresponding light levels. Depending on the source of the signal, you need to attenuate the signal down to a useable level, then run it through a series of Band Pass Filters, then those Band Pass circuits into a series of power circuits sufficient to drive as many LEDs are you need to get the job done. If you intend the Lighting aspect of the system to be as big as you are showing it, then plan on using A LOT of LEDs. There are some circuits that are intended to drive a Spectum Graph, you might be able to adapt these to drive a large bank of LEDs.

Crocodile, I was equally confused which is why I posted both frequency oriented links and sound level oriented links. My initial reactions was Frequency oriented, as he says low bass, mid bass, and high bass. But, I wonder if he doesn't simply mean low level, mid level, and high level signals, implying that this is a VU meter purely to display signal level. So the original poster needs to clear that up. Is he trying to block out the sound spectrum by frequency and display it, as is seen in my first set of videos. Or does he truly mean a VU meter, which is simply signal level based?

VU Meter is an interesting application that acts like a virtual audio level meter. It imitates the volume unit meter of an old stereo, displaying volume indicators on your desktop. I took an old Polish mA-meter from 1968 and turned into nice, vintage-looking VU meter powered by 5V from USB. The electronics is simple - audio amplifier is connected to the galvanometer with.

The last link in post #5 are to VU meter kids. They each level is meant to drive ONE LED. If you want to drive banks of LEDs, then you are going to need more power to drive them, which brings up a separate issue. The OP says he is a student in Electronics, and one assumes as a result, he has the skill to work out some of the details. Notice in Post #4, rather than large banks of LEDs, the person uses fewer LEDs and amplifies the appearance of light with block of Acrylic or Plexiglas. The OP also indicates he wants this to be about 30 inches (700mm) high, again, that is a LOT of LEDs, arranged in complex arrays.

The gizmo in Post #4 appear to be about 18 inches high, perhaps 24' at most. Also notice when the video on Post #4 plays to the end, it then links to a wide range of videos of similar types of LED VU Meters. There are countless videos on YouTube that can help you, and if you find a design that appeals to you, and you have a YouTube account, you can contact that person for more information. Thinks to consider. To see the video in YouTube, rather than here in the post, Right Click, and select 'Copy Video URL' then past that address into a new window or tab. This person also shows the electronics inside the control box near the end of the video, and provides a personal email address.
