This “must have” tool is perfect for any audio-related testing or calibration:
- Test your headphones or speakers
- Set up and calibrate your surround system
- Tune an instrument
- Test your hearing: What frequencies can you hear? (And not hear?)
- Or simply generate annoying noise to drive someone completely nuts ;-)

Features:
- Sine, cosine, square, triangle or sawtooth waves
- Pink or white noise
- Direct frequency input or dial wheel (sweep)
- Frequency range between 20 and 20000 Hz
- Current waveform is shown on your screen

- It’s high-tech, multi-frequency fun at its best!
