What Is Wide Spectrum iOS 15?

Wide Spectrum mode is used to bring in and enhance background noises around you. If you'r trying to use FaceTime for a conference call in the office or to participate in a family gathering, this is the mode to use. 

Much like Voice Isolation mode, it does this through machine learning so your iPhone knows where to focus the sounds on. 

By doing so, other participants on the call can take in more of what's going on around you. It's the reverse of noise cancellation or Voice Isolation, enhancing the sounds around you.

Why Would You Use Wide Spectrum Mode?

Wide Spectrum mode is useful in various situations where you need to elevate the sounds around you. Here's a look at some of the best examples of where it can help.

  • When participating in a group call. Gathered the family around your FaceTime call so everyone can say hi to that relative living away? Turn Wide Spectrum Mode on and everyone can be heard making the experience feel more like you're actually there.
  • When conducting a lesson. If you're trying to perform or conduct a lesson such as a music performance on FaceTime, Wide Spectrum enhances the sound so every detail is captured more appropriately than if Voice Isolation or Standard mode was used. 
  • When wanting to capture a moment better. Simply put, with more background noise and sound, the person you're talking to gets a fuller experience of what you're dealing with. Ideal for those long distance calls where folks think they're missing out.

Does Wide Spectrum Work With Other Apps?

It's possible for Wide Spectrum to work with other apps as Apple hasn't restricted the mode to solely Apple-made apps. However, no third-party apps currently support it. Expect to see it introduced elsewhere in the future. 

Does Wide Spectrum Work With Older iPhones?

Wide Spectrum requires an A12 Bionic chip or newer so it won't work on the iPhone X or older devices. 

FAQ

  • How do I share my screen on FaceTime?

    Use Apple SharePlay to share your device's screen during a call. You can also use SharePlay to stream music and video from a compatible app.

  • Why isn't my microphone working on FaceTime?

    If there's no sound on FaceTime, check your volume and make sure that you haven't muted your microphone. Close any apps that can also use your microphone. If you're still having trouble, check your Wi-Fi or mobile data connection, then update and restart your device.
