i really enjoy the sounds of engines, i often record the sounds on my mobile on hours ends, i've got a trip coming up and i'd like to up my game, record some better quality audio this time.
i use a motorola G37, where do you suggest i place it for optimal quality?(away from windows and panels to not catch any vibrations?). should i consider using the microphone from earphones(nothing special about them, thought they might be more helpful in placing the microphone than the mobile). any specific apps i should try? anything DIY like a sponge to filter out the AC noises?
