ToneFox: Frequency & Sound

ToneFox is a versatile audio frequency generator and sound utility tool designed for audio enthusiasts, sound designers, acoustic testing, speaker maintenance, and relaxation.

Generating pure mathematical waveforms with continuous phase and PolyBLEP anti-aliasing, ToneFox delivers studio-quality audio directly on your device.

KEY AUDIO FEATURES:

PRECISION FREQUENCY GENERATOR • Wide Frequency Range: 1 Hz to 22,000 Hz with micro-step precision (0.1 Hz increments). • 7 Waveform Types:
Pure Sine wave
Band-limited Square wave (PolyBLEP anti-aliased)
Triangle wave
Band-limited Sawtooth wave (PolyBLEP anti-aliased)
White Noise (flat spectral distribution)
Pink Noise (1/f natural acoustic falloff)
Brown Noise (1/f² deep warm rumble) • Dual-Tone & Binaural Beats: Generate two distinct frequencies simultaneously with stereo binaural separation (Alpha, Beta, Delta, Theta). • Continuous Phase Modulation: Glitch-free, click-free parameter transitions with 20ms gentle ramps. • Musical Note Presets: Complete C0 to C8 chromatic scale with standard concert pitch (A4 = 440 Hz). • Frequency Sweeps: Linear and logarithmic frequency sweeps with adjustable duration and loop modes. • Real-time Waveform Display: Visual oscilloscope preview of active sound signals. • Export to WAV: Export generated tones to high-fidelity 16-bit 48kHz WAV audio files.
SPEAKER WATER EJECTOR • Sound-Wave Vibration: Uses specialized dynamic low-frequency acoustic sweeps (130 Hz - 165 Hz) to help dislodge trapped water droplets and dust from speaker grills. • Multi-Stage Pulse Cleaning: Engineered burst patterns optimized for phone speakers. • Home Screen Quick Widget: Run a cleaning cycle with a single tap directly from your home screen.

SPEAKER & STEREO TESTER • Stereo Channel Separation: Test Left / Right channel routing and stereo balance. • Acoustic Sweep Checks: Full-spectrum 20 Hz – 20 kHz frequency sweep to identify speaker rattles, resonance, and dead spots. • Subwoofer Bass Response: Multi-step low-end acoustic check (30 Hz, 40 Hz, 50 Hz, 60 Hz, 80 Hz). • High-Frequency Audibility: Frequency steps (10 kHz, 12 kHz, 14 kHz, 16 kHz, 18 kHz) for acoustic equipment verification.

RELAXING SOUNDS & NOISE • Natural Acoustic Colors: Pure White, Pink, and Brown noise algorithms. • Sleep & Focus Timer: Auto-stop timer with customizable countdown and gentle 5-second fade-out. • Background Playback: Keep sounds playing smoothly when multitasking or while screen is turned off.

AUDIO SAFETY & PRIVACY: • Built-in Safety Limiter: Automatic -2 dBFS headroom protection prevents digital clipping and speaker distortion. • Headphone Protection: Automatic volume attenuation when headphones are plugged in. • 100% Offline & Private: All audio is synthesized algorithmically in real-time. No audio is recorded, stored, or sent to any server.
