How to Use Web Audio Tone Synthesizer & Frequency Lab

Follow these simple steps to process your files securely in browser memory.

1Step 1 of 3

Select Audio Waveform Type

Choose Sine (pure fundamental tone), Square (hollow/reed tone), Sawtooth (bright/buzzy), or Triangle.

Pro Tip: Sine waves contain only the fundamental frequency; Square waves contain odd harmonics.
2Step 2 of 3

Adjust Frequency (Hz) & Volume Slider

Tune pitch from 20 Hz (sub-bass) to 440 Hz (Concert A) up to 10,000 Hz.

Pro Tip: 440 Hz is the standard orchestral tuning pitch (A4).
3Step 3 of 3

Start Tone & Observe Visual Waveform

Click Play to emit real-time synthesized audio through your speakers or headphones.

Pro Tip: Always lower speaker volume before testing frequencies above 5,000 Hz to protect hearing.
