Glintch in the recording

I am using the Rode SmartLav+ mic and I am having glintchs in the recordings... I tested the mic with other Apps and it works just fine. Guess is some problem with the SoundRecorder App... The glintch as a noise associated to it and also cuts some audio... Could you help? I really love your App but is a pitty I can't use it... And I ruined already 3 projects because of this..
