Background info
I have seen great DIY projects where people built their own VU-meter boxes. The VU-meters are visually represented on a display (so the meter itself is not hardware). Here’s two examples:
Most of these projects are built with Volumio software and PeppyMeter plugins for the VU-meters. There is a wide collection of VU-meter visuals to choose from. Which makes it fun because changing to another VU meter of your like, is just a click away.
What I want to do
I would like to use PeppyMeter as active VU meter display, responding to the music streamed via Spotify. So it is all about the visual effect of the VU-meters. I think it looks fantastic!
It is possible to run PeppyMeter as stand alone program. And for audio signal input it woks with ALSA (Advanced Linux Sound Architecture).
My questions
- Does anyone have experience with this? Especially for getting the audio signal output of for instance a Up2Stream Mini, working with ALSA to drive the PeppyMeter VU-meter?
- Does anyone know sources for buying this type of case to fit in the hardware including the display?
All tips and help are welcome!
