1000 Hz Test Tone
Industry-standard 1 kHz reference for calibration and testing.
Fixed frequency: 1000 Hz (1 kHz)
Signal
Standard broadcast test tone — 1 kHz WAV export.
What this tool does
Outputs a 1 kHz (1000 Hz) sine wave — the classic reference for audio level alignment, speaker testing, and informal hearing checks. Because 1 kHz sits near peak human sensitivity, small volume changes are easily noticed.
How to use it
Play the tone and adjust your system volume to a reference level you can repeat later. Use with Speaker Test to confirm mono compatibility. Export WAV for embedding in test playlists or DAW sessions.
Broadcast and studio use
Engineers align meters using known test tones. While professional workflows use calibrated SPL, this browser tool is useful for quick A/B checks, ear fatigue breaks, and teaching how pure tones behave on different speakers.
How to use
Adjust settings
Use sliders and controls to set frequency, volume, and waveform. Changes apply in real time.
