Dog WhistleHow to Use the Pulse Whistle Pattern
Select Pulse to play the whistle with recurring sound and silence. Choose the frequency and playback control before starting. Hold keeps the pattern active while pressed; toggle continues it until stopped. A silent gap belongs to the pattern and does not mean the session has ended. Start at low device volume and stop if discomfort occurs.
Prepare one pulsed playback
Choose Pulse in the pattern controls. Then select a frequency and read the visible setting. The five preset buttons cover 4, 8, 12, 16, and 18 kHz, subject to the current cap. For a nearby pitch, use the 100 Hz coarse steps. Keep the frequency unchanged during your first short playback so there is only one setting to track. Start with low system volume. The app's software gain defaults to 10% and stays within 0–25%. That percentage is separate from the device volume and does not state how loud the speaker will sound.
- Read the selected pattern as well as the frequency.
- Place the speaker away from ears before starting.
- Use a brief playback to check the controls.
Stop the pattern, including its silent gaps
In hold mode, releasing the control ends playback. With toggle, activate the control again to stop. Do not treat a quiet part of the pulse cycle as proof that playback is off. Use the stopping control even if the speaker is silent at that moment. Space toggles and Escape stops when you are outside a typing field. The sound edges use a 10 ms cosine fade. This fade is part of the audio transition; it is not a user timer or a setting for writing your own pulse sequence.
- Keep the page visible until you have stopped playback.
- Check the playback state before putting the device away.
- Use Escape only when you are not typing.
Keep Pulse separate from preset drills
The manual Pulse pattern and the three drills are different controls. In Pulse mode, recurring silent gaps are part of the sound pattern and do not indicate that playback has ended. Attention uses 12000 Hz for 0.3 seconds, followed by a 1.5-second gap and 1.2 seconds on. Settle uses 4000 Hz for two seconds. These names identify fixed app sequences; they do not promise a response from a dog. The drills share a total allowance of three runs per day, with a UTC reset. Selecting Pulse does not turn it into one of those fixed sequences.
- Use the pattern control for manual pulsed playback.
- Read a drill's sequence before spending a daily run.
- Remember that UTC midnight may differ from local midnight.
Check limits before another session
A pulse pattern does not change the frequency ceiling. The minimum is 440 Hz, and the maximum is the browser’s audio sample rate multiplied by 0.45, rounded down. This limits the generated signal; it does not measure speaker output. Many small speakers cannot reproduce ultrasonic tones. Avoid increasing volume to compensate for an apparently silent high setting. Playback stops when the tab is hidden, playback is interrupted or the browser reports an output change. Browsers may miss some changes, so stop before swapping audio devices. Offline browser use requires a first online load. Browser storage can be cleared, and offline use varies by browser.
- Check the output connection after any interruption.
- Stop immediately when a person or dog seems uncomfortable.
- Treat each dog's response as individual, without expecting a training result.
- Pick Pulse and set a frequency that you can read clearly on screen.
- Reduce device volume and choose whether to hold the control or use toggle.
- Start briefly, remembering that silence can be part of an active pulse cycle.
- End the whole session with release or stop, then check its state before switching tasks.
Can I enter my own pulse timings?
The app does not provide custom timers, cue sequences, or macros. Use the Pulse pattern as offered, or choose a fixed drill when its listed sequence is the one you want.
What if the first press produces no sound?
Browser audio can require a direct user action to start. Activate playback on the page and check its state and your output connection. Keep volume low while checking; repeated volume increases are not a useful diagnosis.
Are clickers another pulse setting?
No. Classic and soft clickers are separate marker sounds. Quick yap is also a synthetic marker. Selecting one of them is different from choosing the whistle's Pulse pattern.
