Quiet voice results in null audio file. #56

I'm building an app where recording the user is part of the functionality (for accent analysis) and for the most part this competent works well.

However, for some devices (P20 Pro, I'm looking at you), the microphone input is very quiet unless the user shouts into the primary mike. The secondary mike seems not to be used.

When a user is too quiet, typically this results in recorder.GetAudioFilePath() being NULL. This is frustrating for the users to have to repeat themselves and raise their voice.

Is there any way around this? Will changing the silence threshold help (we are using manual start/stop record)? Can we activate all the microphones on a users phone (there is another on the top)?

Any advice from anyone would help.

i have the same issue in iPhone 11 Pro max. What could be the reason? in the simulator, the voice is clear.

You should set the SilenceThreshold to 0, this defaults to 0.15 as can be seen in the README which causes a silent recording to register as nothing.
