I have a very mysterious issue, my microphone recording is fine on iPhone X but is very very low volume on iPad pro.

It's not the microphone or the distance to the device or anything like that.

My AVAudioRecorder settings are as followed: let recordSettings = [ AVFormatIDKey: kAudioFormatLinearPCM, AVEncoderAudioQualityKey : AVAudioQuality.max.rawValue, AVLinearPCMBitDepthKey : 16, AVNumberOfChannelsKey : 1, AVSampleRateKey : 44100 ] as [String : Any]

If anyone knows a solution I would be very grateful.

Alright, turns out the issue is with adding audio to the ARKit session. No solution yet but at least found the cause.
