>>3687604the thing that will make the heartbeat most apparent is a bass boost centered around 60 Hz. her heartbeat is being transmitted by conduction directly through the microphone housing, and the vast majority of it is below 20 Hz (i.e. out of the range of human hearing). but there is still significant energy between 20 Hz and 100 Hz, and that's the part of it that you can hear.
in her stream audio, it's in both channels, but in the new version posted today (which is what's in this screenshot), it's only in the right channel, because she was using the right ear to capture it. so if you're listening to anon's new version, make sure to listen for it on the right side while you're adjusting your equalizer.
