All throughout the paper they state they used a phone mic.
They have a section on the filtering they needed on the real world audio to extract the information they needed.
The conclusion even states “ We evaluate SpiKey with a proof-of-concept simulation, based on real-world acoustic data, and demonstrate that SpiKey can reduce the search space from a pool of more than 330 thousand keys to just three candidate keys for the most frequent case.”
Why do you claim it’s not real audio?
- justinpombrio 6y agoSection 4 definitely starts with an actual audio recording. But it ends with Figure 7, which shows the relationship between all possible keys and their simulated sounds. The simulation was "based on real-world acoustic data", but figure 7 is not a property of a single actual recording, it is a property of all simulated recordings. You could still be right. I've been reading again, and I'm having a hard time telling apart statements about how their tool works in general, vs. statements of a particular test of it. If they actually tested this thing end-to-end, I would expect to be able to answer (i) how many actual key recordings did they test it on?, and (ii) did it work? Was the actual key found among the 3 (or however many) candidates?
