Dog WhistleHow to Choose a Whistle Frequency
Choose a frequency by setting a visible number, keeping volume low, and checking playback controls before making further changes. onlinedogwhistle.com generates a sine tone from 440 Hz to a device-dependent ceiling. No frequency guarantees a particular response from a dog, and the displayed value does not prove that your speaker reproduces it.
Read the number before playing
Open the whistle controls and look at the current frequency. Hertz, written as Hz, describes the tone frequency. A value of 8000 Hz is also written as 8 kHz. Change the setting while playback is stopped so you can check the number before sound begins. The available range starts at 440 Hz. Its upper end depends on the audio context created by your browser. MDN documents sampleRate as the sample rate used by that context. The app calculates its own ceiling from that value.
- With a 48000 Hz audio context, the calculated ceiling is 21600 Hz.
- With a 44100 Hz audio context, the calculated ceiling is 19845 Hz.
Keep frequency and loudness separate
Frequency selection changes the tone setting. It does not establish sound pressure at your position or at your dog's position. Start with low system volume and keep the device away from ears. The app's software gain defaults to 10%, ranges from 0% to 25%, and cannot describe actual loudness across different speakers. Leave gain unchanged while you inspect frequency settings. This makes the controls easier to follow. Stop if the sound causes discomfort. Do not raise volume simply because a high setting seems silent.
- The displayed frequency identifies the requested tone but cannot confirm what your speaker reproduces..
- A number within the app's range is a digital generation setting, not verified speaker output.
Change one control at a time
Use the 100 Hz coarse controls when you want a nearby value. Use a preset when you want to move directly to one of the five listed frequencies. After either action, read the current setting again. Steady, pulse, and warble are separate playback choices. Keep the same mode while learning the frequency controls, then stop before selecting another mode. The whistle uses a 10 ms cosine fade at sound edges. That fade does not establish speaker quality, comfortable loudness, or a dog's likely reaction.
- Hold playback requires keeping the control pressed.
- Toggle playback continues until you stop it or an automatic stop occurs.
Check stopping and interpret observations carefully
Learn the stop action before trying another setting. Space toggles playback and Escape stops it unless you are typing. Playback also stops when the tab becomes hidden, an interruption occurs, or the app receives a devicechange signal. Browser support for that signal is incomplete, so stop manually before changing audio equipment. If you use the reaction feature, it runs a four-second burst before offering reacted or noReaction. These labels record an observation only. Dogs vary, and neither choice establishes a preferred frequency or a training result. The last three dated outcomes stay locally on the device and can be cleared.
- A missing reaction does not identify whether the speaker reproduced the selected tone.
- A recorded reaction does not measure hearing or explain why a dog responded.
- Lower system volume, place the speaker away from ears, and locate the playback stop control.
- While stopped, select a frequency and read the displayed value against the available range.
- Choose a playback mode and use hold or toggle with the software gain kept low.
- Stop before adjusting another control, switching tabs intentionally, or changing the audio output.
Which frequency should I choose for my dog?
There is no promised setting for every dog. Use the app controls to select a known value, keep sound low, and treat any observation as limited to that moment.
Does an inaudible setting mean the whistle is working?
No. Your perception alone cannot verify speaker output. The displayed number describes the generated signal, while the speaker may reproduce that frequency poorly or not at all.
Why can the maximum differ between devices?
The ceiling follows the actual audio context sample rate. Different contexts can produce different calculated limits. A higher digital ceiling does not establish a wider speaker response.
