external microphone to android connection problem

[kasidokostas]

Hi to all! I am a teacher and I make short films every year with my students. I have a camera which unfortunately has no external microphone port. To get better sound in my movies, I decided to buy the rode videomic microphone this year and pair it with my android smartphone to get the sound and sync it at video editing. The extension cable I use with the microphone is the official that RODE sent me with the microphone. I also bought RODE's Sc4 trs to trrs adapter. Yesterday I took the microphone in my hands, did the “rode videomic + extension cable + sc4 + smartphone (xiaomi redmi note 5)” connection, did some testing and found a very serious problem. During the recording, the sound from the actors' conversations is fine, during the time, however, that there are no speeches in the recording - eg. ambient sound or when actors are walking - the mobile application causes distortion in the sound. Instant breaks. I tried with three android apps (Easy Voice Recorder, Hi-Q MP3 Recorder, RecForge II) and all the same problem. In all three applications I choose to get the sound from the main mobile microphone. How can I fix the problem? I begin to think that I paid the money for the microphone in vain. Thanks in advance.

do you use the dead cat(the foam , fake fur) over the mic, this is designed to deaden wind and background noise. in addition im guessing the mic is directional , so it will pick up mainly from the front. you could point the mic at the person speaking, or alternatively uses wireless mic. this may not be the problem . im guessing this maybe the problem

Is it possible that you have the apps set to auto level? When the actors stop speaking it does sound from your description as though the level is ramping up to try and capture the ambient sounds. If the apps have setting for manual levels then I would suggest this is used and you adjust the level to your requirements.

Unfortunately, android apps have not many tweekings. I just try to turn off auto gain, but it doesn't help.
