eli5 why does everything you play sound worse when in a call?
In: Technology
Do you mean if you play music to someone through the phone and they hear it as a garbled mess?
Phone lines use compression to be able to send more data and handle more calls at once. Speech has a certain range of pitches of sound that are used. You can strip some of them away and it still sounds fairly normal. On the other hand, music tends to use a much wider range of frequencies. When you hear a note, you’re also hearing a bunch of higher notes that give it a certain colour. When the same compression gets applied to music as to speech on the phone, it sounds terrible.
