About this app

Frequency Sound Generator is the ultimate, high-precision audio tool and tone generator for creating specific sound waves, frequencies, and tones. Whether you are an audiophile, sound engineer, musician, or simply want to relax, sleep better, or test your hearing, this hz generator app delivers an incredibly accurate frequency range from 1 Hz to 22,000 Hz.

Experience a Zero-Latency Audio Engine that guarantees perfectly stable pitch without any stuttering or memory leaks, ensuring your audio tests and relaxation sessions are 100% accurate.

🎛️ Generate Any Waveform
Easily switch between standard waveforms to suit your acoustic and sound generation needs:
• Sine Wave: Pure, smooth tone. Perfect for hearing tests, instrument tuning, and sleep sounds.
• Square Wave: Rich in odd harmonics. Great for testing distortion and synthesizers.
• Sawtooth / Triangle Waves: Sharp, piercing sounds for audio masking, aggressive tone testing, and clearing water from speakers.

🚀 Key Features & Capabilities
• Extreme Precision: Generate any exact frequency (e.g., 432 Hz, 528 Hz, 440 Hz) using the intuitive logarithmic slider or manual keyboard input.
• Frequency Sweep: Automatically transition from one frequency to another (Linear or Logarithmic) over a set duration. Excellent for testing speaker crossovers and subwoofer bass ranges.
• Multi-Tone Engine: Mix up to 20 different frequencies simultaneously. Create complex chords, binaural beats, or white noise masking.
• Pick a Note: Direct conversion of standard musical notes into exact frequencies.
• WAV Audio Export: Save your custom generated frequencies as high-quality .WAV files (44.1kHz / 16-bit PCM) directly to your device.
• My Presets: Save your favorite frequency and waveform combinations for quick access later.
• Background Playback: The audio continues to play seamlessly in the background even when the screen is off or the app is minimized. Perfect for adding a frequency sound to the background while listening to music on other apps, or while sleeping!

🎧 Common Use Cases
• Sleep & Relaxation: Listen to frequency sounds while sleeping to improve sleep quality or create a calming atmosphere. Add frequencies to your background music.
• Binaural Beats & Meditation: Create 432 Hz, 528 Hz healing tones or binaural interference patterns for deep focus, study, and relaxation.
• Tinnitus Relief: Generate masking frequencies and white noise to help relieve the ringing in your ears (tinnitus).
• Hearing Tests: Discover the highest and lowest frequencies your ears can detect with our hz generator.
• Speaker & Headphone Testing: Clear out water and dust from your phone speaker, test subwoofer bass response, or check for speaker distortion.
• Instrument Tuning: Output a perfect A4 (440 Hz) tone to tune your guitar, piano, violin, or other instruments.
• Dog Whistle: Generate high-frequency sounds (15,000 Hz+) to train your pets or stop dogs from barking.

🛠️ Advanced Engineering
Built with native modern architecture, the app features a custom Zero-GC (Garbage Collection) audio loop. This means the sound will never pop, crackle, or interrupt your experience. Combined with a sleek, Dark Mode optimized UI, the application is battery-friendly and extremely fast.
