## What is Spectrum Lab?

A real-time audio spectrum analyzer with a fast, responsive display.

Monitor live frequencies from any input source, including built-in microphones, USB devices, and Bluetooth audio. Peak detection helps you track signal changes instantly and see how your signal evolves over time.

Use it to analyze music, inspect mixes, and understand the frequency balance of tracks in real time. Check how different environments affect sound, identify noise or unwanted frequencies, and get a clear view of what your microphone is actually capturing.

Test speakers, headphones, and audio equipment to see how they respond across the frequency range. Useful for quick checks, setup validation, and comparing different devices or signal paths.

Also helpful during development and debugging - visualize audio output, verify signal presence, and monitor changes instantly without needing complex tools.

Designed to be simple and direct: no manual configuration, no unnecessary controls. Just open the app, select your input, and start analyzing.

No setup required. Everything runs automatically.
