IPhone 14 blocks a whistle during calls

I am a Whistler. I do frequent video calls using WhatsApp and FaceTime with my grandson (a four month old baby!).

One way I used to entertain him whenever I was with him was to whistle to him. And he used to love it!Now, when I try the same on a video call, I realize that my iPhone completely blocks out the whistle sound! I mean completely! it’s almost as if the mute button has been pressed. My voice goes through perfectly fine, but the whistle is completely blocked. I know there is no problem with my microphone since I can record a video with a whistle and the whistle gets recorded perfectly fine. I can then send the recorded video to him using WhatsApp and everything works fine. But the whistle sound is blocked during a live call.

Does anyone know how I can get around this? I need to be able to have a live video call with conversation as well as a whistle sound.

Thanks for any help!

iPhone 14, iOS 18

Voice isolation is turned off. I think Wide spectrum setting is not available on the iPhone 14.

Hi there!

Possible Fix for Whistle Sound Being Blocked on iPhone Calls:

It’s likely due to noise suppression (Voice Isolation). Try this:

1. Enable “Wide Spectrum” (FaceTime Only)

• Start a FaceTime call.

• Open Control Center (swipe down from the top-right).

• Tap Mic Mode and select Wide Spectrum.

2. Use a Wired or Bluetooth Microphone (AirPods or wired headset).

3. Try a Different App (Zoom or Skype may not block the whistle).

4. Change the Pitch of Your Whistle (higher/lower may work).

5. Record and Send Instead (since recordings work fine).

Hope this helps!

One update to my earlier post: The whistle sound works on Facetime calls! So, it is clear that there is nothing wrong with my iPhone. Looks like it is a whatsapp setting problem.

With that I think I will terminate this thread since it is not about iPhone.

Thanks for everyone who took the time to respond. Truly appreciate your effort.

Cheers!

Check if Wide spectrum is enabled on your phone and make sure voice isolation is turned off. If it still doesn’t work then check WhatsApp voice isolation settings.

Hope that helps.

Hello @Alexmath998,

Thank you for taking the time to reply.

I tried whistling in higher and lower pitch. It’s still blocks all frequencies.

I used WhatsApp for video calling. My whistle is blocked, but if my son whistles on the other side, I can hear it perfectly. So it’s something that my phone is doing and not the video calling app.

I have switched off voice isolation in the iPhone accessibility settings. So that is not the reason either.

The mystery continues!
