We are talking about acoustics, sub 100khz signals. They are not talking about catching emanations from sound codecs or key strokes they are talking about CPU instructions for crying out loud. There is certain loss of information when we are talking about catching x86 instructions happening in 3Ghz. Paper does not really explain this.
