How come the phone microphone is significantly less sensitive when calling someone than when you’re recording video/audio?
In: Technology
Standard telephones sample the microphone 8,000 times per second (8,000/s) which is sufficient for reproducing normal speech. When you record an audio or video file for playback, the microphone is normally sampled 5 (40,000/s) to 20 (192,000/s) times more frequently to capture the higher frequencies to the musical instruments. When you increase the sampling count per second, you are able to reproduce the original sound in greater detail.
