Simply set the frequency for the left and right channels by moving the scale left/right, or specify the desired values from 1 to 20000 Hertz in the appropriate fields and press Play. You can change the frequency value for the left and right channels right during the signal playback, choosing interesting combinations of two tonal sounds. Experiment by changing frequencies, thereby creating interesting sound effects. You can also download high-quality samples in WAV audio format.

In addition, you can test your headphones (left and right channel) and check their operation at different frequencies. If your headphones reproduce frequencies from 30 Hertz (Hz), set this frequency and you should hear the signal normally.
