High-frequency sounds (ultrasonic waves) push hardware to its absolute limits. If you or your pets aren't reacting to the frequencies, use these configuration tips:
🌐 RECOMMENDED BROWSERS
Desktop: Google Chrome or Mozilla Firefox offer the most stable implementation of the Web Audio API for constant high-frequency waves.
iOS (iPhone/iPad): Safari is recommended, but note that iOS aggressively silences background browser audio. Keep the tab open and active.
Android: Google Chrome Mobile provides the best performance and lowest latency.
🔊 SPEAKER & HARDWARE GUIDE
Premium Mobile Devices: Newer flagship phones (like iPhone 12+, Samsung Galaxy S21+, or Pixel 6+) generally have wider-range built-in stereo speakers that can successfully emit frequencies up to 18–20 kHz.
Budget/Older Phones & Tablets: Built-in speakers on older or lower-end devices often physically cannot produce sounds above 12–14 kHz. The software might say it's playing, but the hardware is completely silent.
The External Speaker Secret: For the absolute best results, connect your device to a high-quality external Bluetooth speaker or dedicated PA system that explicitly lists support for high-frequency audio output.
⚠️ SAFETY WARNING
Standard Bluetooth headphones or earbuds will work, but never use them at high frequencies while a human or animal is wearing them, as it can cause sudden hearing discomfort or damage.
