About Audio Generator
The Pure Tone Sine Wave & Acoustic Frequency Generator synthesizes pure mathematical sine wave tones (1Hz to 24,000Hz) with precision decimal tuning, frequency sweeps (chirps), binaural beat frequency pairing, and lossless WAV export.
How to Use Audio Generator
Step 1
Enter target frequency in Hz or select a musical note preset (e.g. 440Hz A4).
Step 2
Adjust volume level and set generation duration (seconds).
Step 3
Listen to the live tone generator preview.
Step 4
Click "Download Tone WAV".
Practical Use Cases for Audio Generator
Calibrating Subwoofers & Testing Room Bass Resonance (20-100Hz)
Generate continuous 40Hz, 50Hz, and 60Hz pure sine tones to test subwoofer bass response and locate physical room rattles.
Generating 432Hz / 440Hz Concert Pitch Tuning Tones & Binaural Beats
Generate precision 440Hz A4 tuning reference tones or binaural alpha/theta brainwave frequencies (e.g. Left 200Hz, Right 208Hz = 8Hz Theta beat).

Key Terminology & Definitions
Pure Sine Wave
A fundamental acoustic waveform consisting of a single pure frequency with zero harmonic distortion or overtones ($y(t) = A \sin(2\pi f t)$).
Binaural Beat
An auditory illusion perceived in the brain when two slightly different pure tones are presented separately to each ear via headphones.
