Test Signal.

Use one page for tones, noise, sweeps, bursts, impulses, routing, polarity, and phase tests.

Safety: Start with your speakers, headphones, and interface volume turned down. Test tones and noise can become loud very quickly.

Included Generators

Ten Tools.
One Pack.

Sine Wave

Pure single-frequency tone for speaker tests, crossover checks, room modes, and ear training.

Square Wave

Odd-harmonic test signal for checking transient response, distortion, and system behavior.

Triangle Wave

Softer harmonic waveform for calibration and waveform comparison.

Sawtooth Wave

Full harmonic series for testing bandwidth and harmonic response.

White Noise

Equal energy per Hz for broad system and component testing.

Pink Noise

Equal energy per octave for monitor calibration, room analysis, and tonal balancing.

Brown Noise

Strong low-frequency emphasis for subwoofer and low-end testing.

Frequency Sweep

Logarithmic sweep for finding resonances, nulls, rattles, crossover issues, and bandwidth limits.

Burst Generator

Repeated short tone bursts for transient, resonance, and decay testing.

Impulse Generator

Short clicks for testing timing, echoes, channel routing, and impulse response behavior.

Professional Uses

What To Test
With It.

Studio Calibration

Use pink noise, 1 kHz tones, and low-frequency sweeps to balance speakers and subwoofers.

Speaker Testing

Check left/right routing, distortion, rattles, tweeter response, woofer response, and crossover behavior.

Ear Training

Practice identifying frequencies and tonal regions using exact tone presets.

Acoustic Treatment

Use slow sweeps and pink noise to identify room resonances, dead zones, and flutter echoes.

Equipment Troubleshooting

Trace channels, compare polarity, verify signal flow, and test cables, interfaces, mixers, and monitor paths.

Safety & Accuracy

Use Test Signals
Carefully.

Start Quiet

Begin at a very low hardware volume. Test signals can reach full-scale quickly even when they do not sound loud.

Protect Tweeters

Square and sawtooth waves contain strong harmonics. Avoid high levels, especially at high frequencies.

Protect Woofers

Low-frequency sine waves and brown noise can create high cone excursion. Do not run them loudly for long periods.

Browser Output

The digital level is controlled here, but your interface, operating system, amplifier, and speaker volume still determine the final acoustic level.

Every Test Signal.
One Studio.

Use one browser-based generator pack for calibration, speaker testing, ear training, acoustics, and troubleshooting.
