Description
Frequency Generator - Professional Audio Toolkit
Generate precise audio frequencies, binaural beats, noise, and more with this comprehensive audio generation app. Whether you are testing audio equipment, experimenting with sound therapy, creating sound effects, or cleaning your phone's speakers, Frequency Generator has everything you need.
🎵 Main features
Single Oscillator Generate pure tones from 1 Hz (infrasound) to 22,000 Hz (ultrasound) with precise frequency control. Choose from multiple waveforms including sine, square, triangle, and sawtooth. Perfect for audio testing, speaker calibration, tinnitus relief, or scientific experiments.
Multi-Oscillators Combine multiple oscillators to create complex harmonic sounds and chords. Layer different frequencies and waveforms to experiment with acoustic phenomena and interference patterns.
Synthesizer Craft your own sound and play musical notes on a full-featured synthesizer with customizable tuning frequency (A4). Perfect for musicians, composers, and music students.
Binaural Beats Create and experiment with binaural beats for relaxation, sleep or meditation. Best experienced with headphones.
Sweep Generator Generate frequency sweeps, ideal for speaker testing, room acoustic analysis, and finding resonant frequencies. Add multiple sweeps and create loops.
Noise Generator Generate white noise and other colored noises. Includes advanced effects like auto-pan and breathing for enhanced relaxation and focus. Great for sleep, concentration, or masking unwanted sounds.
Bass/Subwoofers Test Test your audio system's low-frequency capabilities. Find out how low your subwoofers, headphones, or speakers can go.
Speaker Cleaner Remove water from your phone's speakers using specific sound frequencies. If your speaker sounds muffled after water exposure, this tool can help eject the liquid.
DTMF Tone Generator Generate dual-tone multi-frequency signals used in telecommunications.
SFX Generator Create random retro-style sound effects like coins, lasers, explosions, jumps, and more. Save your favorite sounds as WAV files.
⚙️ Advanced features
• Precision: Supports decimal values (e.g., 7.83 Hz, 432.1 Hz, 528.5 Hz) • Advanced Effects: Vibrato (FM), Tremolo (AM), Ring Modulation (RM), PWM • Stereo Control: Independent left/right audio balance • Presets: Save and manage your favorite configurations • Audio Export: Export your sounds as high-quality audio files • Background Mode: Continue playing while using other apps • Timer: Automatically stop playback after a set duration
⚠️ Safety & Usage information
Hear Safely Always use this app responsibly and keep volume at reasonable levels to protect your hearing and audio equipment. Low frequencies may sound quiet, so if you increase volume to hear bass tones better, remember to lower it before playing higher frequencies—perceived loudness varies significantly across the frequency spectrum.
Mosquito Repellent Disclaimer Scientific studies have consistently shown that ultrasonic frequencies are NOT effective at repelling mosquitoes. While some apps claim to work as mosquito repellents by generating ultrasounds (15,000-22,000 Hz), there is no reliable evidence supporting this use case.
🎯 Use cases
• Audio equipment testing and calibration • Speaker and headphone frequency response testing • Tinnitus relief and sound therapy • Meditation and relaxation with binaural beats • Sleep assistance with noise generation • Musical instrument tuning and ear training • Physics and acoustics education • Dog whistle and ultrasonic experiments • Room acoustics analysis • Phone speaker water removal • Sound effect creation
Whether you are an audio professional, musician, student, or just curious about sound, Frequency Generator provides powerful tools in one convenient app.

I got this to prevent an issue with my USB headphones where sound cuts out at moments below a certain noise threshold. App allows me to play a low, inaudible frequency in the background to keep sound active while watching quiet movies or shows. This alone earned it 5 stars, but there's also a bunch of others cool features like a synth keyboard with multiple wave patterns and a random sfx generator and even a tool for cleaning a wet phone speaker. Very fun to mess around with!

This dual-frequency generator application is well-designed for functionality and for interface comfort. The oscillators are of high quality and fully adjustable to save as presets. The Pro version has even more oscillators that accommodate binaural stimulation. The price-over-function is yet another surprise at $4.99 - a one-time registration. Thank you, Team Hoelboedec.dev for delivering a superb product at an unbelievable price.

Been using it for years, and it's never let me down it works great, the frequency is what it is. it helps me sleep meditate and calm down when needed. Easy to understand and navigate. Only thing it lacks is a list of things the frequencies help with 174 good all round soothing and calming. With a bit of research you'll find there is alot you can benefit from using this technology for better health.

The app was great, now we get full screen inappropriate ads when you launch it. No, thank you.

🥺 It was My favorite until they updated it, and now it doesn't even play in the background or even for a long time even though the setting is set for 12 plus hours. What happened?

This is/would be the perfect app if the audio was stable. Unfortunately the right channel fluctuates. If this can be fixed, you have my money.
