What Can You Do?
Audio Equipment Testing
Before: You need a pure reference tone to test speakers, headphones, or amplifiers.
After: Generate a clean sine wave at any frequency. No harmonics, no distortion — just a pure tone.
System Calibration
Before: Your audio system needs calibration with a known reference signal.
After: Use 1kHz sine wave as a standard reference level for calibrating levels across your chain.
Acoustics Education
Before: Students need to hear pure tones to understand frequency, pitch, and wavelength.
After: Play different frequencies. Show the wavelength calculation. Demonstrate the relationship.
