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.

Good, but weird. It's good because I like the binaural beats with it. And it's weird because the multi tone bit is buggy the right sound seems fine but the left sound mutes.

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.
★★★★★py haguier· Nov 10, 2025
This app delivers the most accurate frequencies, especially with multi-oscillators, the algorithm behind is impressive, whatever low, high frequencies mixed together, the audio output adapts perfectly, even not achievable with audacity.... suggestions: would be great to extend the number of frequencies in the multi-oscillators up to 10, I would pay for that UPDATE: thanks for the 10 multi-oscillators, upgraded to pro!

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

I above know this a limitation of truth... I would love to feel assured of picking any frequency I willingly chose. But it appears that I'm limited to lower frequencies... which as I could only see fit to abandon🧘🧘🧘🙏🙏🙏✌️💜💜💜💜💜💜💜💜💜

🥺 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?
★★☆☆☆Michael· Mar 13, 2026
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.
★☆☆☆☆A GIGGLE USER· Mar 25, 2026
