## What is Overtone?

Acoustic Analyser is a real-time audio measurement tool for musicians, technicians, and sound designers. It visualizes live microphone input in both the time and frequency domains, explicitly bypassing standard OS voice processing (like auto-gain and noise suppression) to give you an uncolored, accurate reading of your acoustic environment.

Features: 
• Waveform & Spectrum Views: Monitor live audio blocks and view averaged magnitude spectrums on a log-frequency axis (20 Hz to Nyquist). 
• Accurate Peak Detection: Automatically identifies prominent frequencies with sub-bin precision and dynamic range gating. 
• Pitch & Harmonic Readout: Tap any peak to view its exact frequency, nearest equal-tempered musical note, cents deviation, and harmonic ratios. 
• Tone Playback: Audition isolated frequency peaks as pure sine waves with equal-loudness compensation. 
• Adjustable Parameters: Fine-tune your analysis with customizable FFT sizes, averaging modes (exponential or peak hold), and display offsets.
