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.
