The recorded sounds won’t always sound too clear as all recording apps rely on the phone’s microphone. And considering cell phone models come with a varying number of microphones, the clarity of the recorded sounds is highly contingent on that. The general rule, in this case, is that the more microphones a phone has, the better the audio signal is going to be. Background noise and other chatter do bleed in too, as active noise cancellation isn’t supported by any iOS or Android spy to listen to surroundings.
