Wide Spectrum is useful for calls with multiple people on one phone line. That way, everyone can be heard, not just the person holding the phone.
Currently, Wide Spectrum is only available for FaceTime Calls, not phone calls. Since the feature is still present in microphone mode when accessed during a phone call, it is possible that this feature will be available for phone calls in the future.
