Sound generator

A sound generator for playing audio frequencies of different waveforms, frequencies, and volumes. This simple yet powerful tool is useful for:

• Testing headphones and speakers at a specific frequency

• Physics experiments with sound

• Playing multiple tones at once (beat frequencies, mixing)

• Relaxation or meditation

• Hearing tests

• Dog training (dogs hear ultrasound well)

Key features of the sound generator:

📈 Waveform

For each tone, choose a waveform: sine, saw, square, or triangle.

📊 Amplitude

Adjust volume flexibly — set individual amplitude for each tone.

📉 Phase shift

Play multiple tones with stereo effects using phase control.

🔈 Audio channel

Set the output channel for each tone: left, right, or both.

🎛️ Wide frequency range

Choose frequencies from low bass to ultrasound.

💾 Saving presets

Save and load tone sets to reuse them without reconfiguring.
