Take VU meters for example. They’re a super useful tool for audio editors to balance signals ... [mircemk]’s OLED version that displays dual analog meters.

We’ve seen other VU meter builds before too, like this one that uses a little physics knowledge to create a more realistic analog-like needle meter. Video after the break.

VU meters measure the volume (intensity) of analog audio signals. They display signal levels in volume units (VU), a measure of average volume level. By definition, a volume indicator (VI) reading of ...
