But it cannot be used for cellular calls. FaceTime has a new noise cancellation feature, called “Voice Isolation”. If you’re on the street or in a loud bus, the person you’re calling won’t understand a thing. IPhone 12 lineup and lower have a front mic that is used for noise cancellation. This supposition is actually incorrect, however the microphone is there, but for whatever reason, the setting to control it is not. The original poster suggested that this is because the iPhone 13 lacks the extra mic used for noise cancellation. This first came to light about two weeks ago in a Reddit thread. Cut out the clutter: these are the only 6 iPhone apps you’ll ever need.Īlthough this option is normally enabled by default, since it’s not present on the iPhone 13, it’s unclear whether that means those iPhone models don’t support noise cancellation for phone calls, or whether Apple just isn’t letting people turn it off. The App Store has become completely oversaturated with all the same, repetitive junk. The phone is Samsung Galaxy S7 with android 8.0, but I am looking for a a general solution if it exists.6 Apps You Should Absolutely Have On Your iPhone I would like to know if there is a way to completely prevent the phone from doing any kind of audio processing, at the mic or the speaker side, through some option in the phone settings or through adb or in my program's code. MIC would be the option without any preprocessing attached to it. _RECOGNITION doesn't seem to have any effects on the input sound, but I would have guessed that or. AudioRecord source is ( gives the same result). I use AudioRecord class to get microphone audio samples and AudioTrack to play them back. Is there any way to completely stop or bypass any kind of preprocessing the phone does to the microphone input samples, or to the output samples?I have looked at all the sound related settings on the phone and they are all disabled, at least as far as I can tell. I think some kind of built in noise reduction or some other effect is kicking in when I blow into the microphone However, if I blow into the microphone, I can momentarily notice the sound in the earphone going smaller, which slowly rises back to its normal volume Normally I can hear what I say into the microphone loud and clear on the attached headphone I have made a program that reads a fixed number of bytes from the microphone and sends it out to the speaker, effectively a program to route audio from the mic to speaker without any changes
