[Notice: please switch to "Microphone Pro" if you encounter noise]
Since the android 7.0 os update some phones will encounteer noise problem while this app "Microphone Pro S" is running in the background. The sound will be good if the application is in the front but when user press home to put the application into background then noise may occur. We hope that the next software update from manufacturer will fix this problem. You could send feedback to manufacturer so they will resolve this issue sooner.

This version may have a small delay if there is no sound please read more help at the menu on top. You could try to increase the frames_per_buffer: try 48000Hz-1440 or 16000Hz-960...
