Tone & sweep generator
Sine, square, sawtooth and triangle tones or a logarithmic sweep, with a safe output limit.
Hz
1 – 22000 Hz
Square and sawtooth waves contain strong harmonics and sound louder than a sine at the same level. Use sweeps to find resonances, rattles and cabinet problems.
How it works
Play a reference tone to check speakers, find rattles, or identify a resonance. A logarithmic sweep passes through each octave in equal time, which is the usual way to scan the audio band.
The output is capped at −6 dBFS and starts at −30 dBFS. Raise your system volume carefully: sine waves at high levels can damage tweeters and hearing.
