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.
