Say goodbye to muffled audio and trapped liquid with Sound & Frequency Test, the ultimate audio companion for your iPhone. Whether you need to eject water from your device’s speakers, test your audio equipment's performance, tune an instrument, or explore the limits of human hearing, this app delivers studio-grade accuracy with a stunning, modern dark design. Our app utilizes a custom, manually-scheduled PCM buffer loop to generate pure sine-wave tones with sample-accurate precision. Enjoy seamless frequency sweeps without pops, clicks, or distortions. KEY FEATURES: 1. AUTOMATIC WATER EJECT & SPEAKER CLEANER Accidentally dropped your phone in water? The dedicated Water Eject mode uses a scientifically proven 165 Hz frequency to vibrate the speaker diaphragm, effectively expelling trapped water and restoring crystal-clear sound quality in just 30 seconds. 2. PRECISION TONE GENERATOR Produce pure sine waves across the full spectrum of human hearing, from a deep sub-bass 20 Hz to a high-pitched treble 22,000 Hz. Adjust the frequency smoothly using the logarithmic slider or precise manual controls to suit your audio needs. 3. REAL-TIME NOTE DETECTION Curious about what musical note you’re playing? As you adjust the frequency, the app automatically calculates and displays the corresponding musical note name and octave in real-time (e.g., A4, C0). 4. ONE-TAP SOUND PRESETS Instantly jump to standard reference frequencies: • Water Eject (165 Hz) — Vibrate and clear your speakers. • Bass Test (60 Hz) — Test subwoofers and low-end responses. • Mid Test (1,000 Hz) — Check mid-range audio clarity. • Treble Test (8,000 Hz) — Check high-frequency performance. • Concert A (440 Hz) — Classic standard tuning pitch for musicians. 5. AMPLITUDE & VOLUME CONTROLS Fine-tune the output intensity of the generated frequencies directly in the app. Combined with visual representations of the audio waves, you maintain full control over your acoustic experience. 6. SAFETY WARNING SYSTEM & USER EDUCATION High-frequency tones can be intense. We prioritize your hearing safety by incorporating an in-app safety guide and automatic volume warnings to prevent hearing damage. PRACTICAL USE CASES: • Speaker Restoration: Clean your phone's speaker grill after water exposure, dust accumulation, or lint blockages. • Audio Equipment Testing: Check the frequency response of headphones, earbuds, home studio monitors, subwoofers, and Bluetooth speakers. • Instrument Tuning: Use standard reference tones like Concert A (440 Hz) to tune guitars, violins, pianos, and other instruments. • Sound Projects & Experiments: Ideal for acoustics study, physics demonstrations, and sound-wave analysis. • Hearing Assessments: Explore your personal upper and lower hearing thresholds.
