AnalogVUMeter – classic analog stereo VU meter

AnalogVUMeter is a cross-platform desktop application that visually replicates a classic analog stereo VU meter (needle-style) using Qt 6 custom painting and native audio APIs.

This is free and open source software.

Features include:

• Stereo (Left/Right) analog VU meters with a retro hardware aesthetic.
• RMS-based level measurement with classic VU ballistics:
  • Vintage hi-fi style attack/decay.
  • Slight transient overshoot.
  • Subtle needle “life” (very small jitter).
• ~60 Hz refresh rate.
• Multi-threaded audio capture (non-blocking GUI).
• System output monitoring (captures audio playing through speakers).
• Microphone input support.
• Runtime-importable custom meter skins.
• Cross-platform support: Linux (PulseAudio/PipeWire) and macOS (CoreAudio).
