Professional Audio Testing Online
A tone generator is an essential diagnostic tool for audio engineers, musicians, and hobbyists. By generating mathematically pure waves, you can test the frequency limits of speakers, identify resonant frequencies in a room, or even aid in scientific hearing tests.
Waveform Breakdown
- Sine: The purest sound—a single frequency with no harmonics. Used for testing audio transparency.
- Square: Rich in odd harmonics. Ideal for testing compression and digital clipping.
- Sawtooth: Contains both even and odd harmonics. Great for synth-style tuning and mapping.
- Triangle: A softer version of the square wave with lower harmonic content.
Safety Warning
> [!WARNING] > Be careful when using high frequencies (above 15kHz) or high volumes with headphones. Prolonged exposure to pure tones can damage hearing or equipment. Start at **10% volume** and increase slowly.
Instruction: How to use
1. **Activate:** Click the large blue play button. Browsers require a "user gesture" to start audio.
2. **Select Wave:** Choose your waveform based on the complexity of harmonics you need.
3. **Adjust Frequency:** Use the slider or frequency steps to find your target Hz.
4. **Analyze:** Watch for distortion or drop-outs in your hardware as you sweep through frequencies.
