How to Use the Whistle with a Bluetooth Output
Connect your Bluetooth speaker through your device settings while the whistle is stopped. Confirm that it is the selected audio output, lower system volume, and start with a brief hold. Stop playback before disconnecting or switching devices. The app cannot guarantee that the browser reports every Bluetooth output change.
Connect first, then open the playback controls
Keep the whistle stopped while pairing or reconnecting the Bluetooth speaker. Use your phone or computer's audio settings to select the intended output. Check the selected device rather than relying only on a connection message. Place the speaker away from ears and start with low system volume. If the chosen Bluetooth device is a headset or earbuds, remove it before playing the whistle. Return to onlinedogwhistle.com once the output choice is settled. Browser audio may require a direct user action before playback begins. Use the app's playback control after returning to the page.
- Read the output device name in system settings.
- Complete connection changes with the tone off.
Check settings without chasing silent frequencies
Choose hold mode and review the visible frequency before playing a short tone. The five presets request 4, 8, 12, 16, and 18 kHz. The app limits them to its current frequency cap when necessary. That cap equals the browser’s audio sample rate multiplied by 0.45, rounded down to a whole number. It limits the generated signal; it does not measure the Bluetooth speaker’s output. With playback stopped, connect your Bluetooth speaker and confirm the selected output in device settings. The app does not measure an external speaker’s response. If a setting seems silent, end playback and check the selected output. Do not raise volume to pursue an inaudible tone.
- Check the displayed value after selecting a preset.
- Keep software gain and system volume as separate checks.
Handle a dropped connection with playback stopped
If the connection becomes uncertain, press Stop before opening Bluetooth settings. The whistle stops when its tab becomes hidden, when audio is interrupted, or when a devicechange signal arrives. Those safeguards do not mean every wireless route change will be reported. Browser support for devicechange is incomplete. A missing signal is not confirmation that the original speaker remains selected. Reconnect the device, inspect the current output, and lower system volume again before restarting. Leave the whistle off if you cannot tell which output is selected. Do not use repeated tone starts as a substitute for checking system settings.
- Stop before deliberately disconnecting the speaker.
- Check the route again after any reconnection.
Keep the restart brief and under your control
Software gain defaults to 10% and cannot exceed 25%. These values do not state the loudness produced by the connected device. Use a brief hold after reconnection, then release it. Toggle mode is available when you want playback to continue until stopped. Steady, pulse, and warble offer different patterns, with a 10 ms cosine fade at tone starts and finishes. None verifies speaker performance. Space toggles playback and Escape stops it when you are not typing. Keep a visible stop control available. Stop if uncomfortable, and remember that dogs vary; playback settings carry no promise of a training result.
- Review mode and gain after returning to the app.
- Keep the speaker at a distance throughout playback.
- With playback off, connect the Bluetooth device and select it as the system audio output.
- Place the speaker away from ears, reduce system volume, and inspect the app's current gain and frequency.
- Press and release the hold control for a brief playback; stop if the route or sound is uncertain.
- Before switching outputs, stop manually; after reconnecting, repeat the output and volume checks.
Does a Bluetooth connection message prove where the whistle will play?
Check the selected audio output in system settings before starting. A connection message alone is not the output check described here.
Why can the screen show a high frequency without audible sound?
The screen reports the generated setting. It does not confirm that the connected speaker reproduces that frequency.
Can I depend on automatic stopping when Bluetooth disconnects?
No. The app stops on a received devicechange signal or audio interruption, but every route change may not be reported. Stop manually before switching.
