Frequency Sound Generator

Frequency Sound Generator is a professional tone generator and frequency generator designed for audio testing, speaker testing, instrument tuning, and sound experiments.

Generate precise tones from 1 to 22,000 Hz. Create frequency sweeps, test audio equipment, and control waveform, volume, stereo balance, and playback via a clean, responsive interface.

⚙️ KEY FEATURES

• 1 to 22,000 Hz tone generator
Generate specific frequencies such as 440 Hz or 10,000 Hz. Enter an exact value or adjust frequency with the logarithmic control.

• Multiple waveforms
Choose Sine, Square, Sawtooth, or Triangle waves for audio testing and sound-generation.

• Frequency sweep generator
Create automatic frequency sweeps between a start and end frequency. Choose Linear or Logarithmic sweep behavior and set duration.

• Multi-tone generator
Mix up to 20 oscillators at the same time. Set individual frequencies, waveforms and volume levels to create layered tones, chords and test signals.

• Musical note generator
Select a musical note and instantly generate its frequency. Useful for instrument tuning, ear training and music experiments.

• WAV audio export
Export tones as 44.1 kHz, 16-bit PCM WAV files for offline playback and audio testing.

• Presets
Save frequently used frequency and waveform combinations and recall them instantly.

• Background playback
Keep tones playing while the app is minimized or the screen is off.

🔊 AUDIO TESTING & USE
Use it as a tone generator, frequency generator, speaker tester, headphone tester, subwoofer test tool, tuning reference, or high-frequency generator.

Try low-frequency tones to explore bass and subwoofer response. Use frequency sweeps to check how speakers respond across a range. Generate an A4 440 Hz tone for tuning instruments. Explore high-frequency tones within the limits of your device.

🎛️ FOR AUDIO USERS & SOUND ENTHUSIASTS
Whether you are a musician tuning an instrument, an audio engineer testing equipment, a student exploring acoustics, or curious about sound waves, this app gives you precise controls.

👂 HEARING EXPLORATION
Explore which frequencies you can hear and compare tones. Hearing ability varies with age, listening level, and device hardware. This app is not a medical hearing test.

🧘 RELAXATION & BINAURAL BEATS
Create steady tones or combine frequencies for relaxation and focus. For binaural beats, use headphones and set different tones for left and right channels.

💧 SPEAKER CLEANING
Certain frequencies may help move water from a speaker after minor moisture exposure. Results depend on speaker design. This feature cannot repair liquid damage.

🐕 DOG WHISTLE & HIGH FREQUENCY
Generate tones above 15,000 Hz for experiments and training applications. Actual playback depends on your device; many cannot reproduce the highest frequencies accurately.

⚠️ IMPORTANT
Audio hardware differs. Built-in speakers and headphones have different frequency responses and may introduce distortion outside their supported range. Use safe listening levels.

All core features are free. An optional in-app purchase is available to remove ads.
