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.
