About Emergency Frequency: 404

You are working a radio desk where a convincing voice is not enough to prove that a caller is human. Tune the analysis equipment, inspect the signal and use the response switches carefully. The tutorial introduces the difference between irregular human waveforms and suspiciously clean anomalies.

How to Play

Use the mouse to operate the radio interface and low-pass filter. Read the dossier and tutorial before choosing between the green, red and black response switches.

Playing Tips

Check the waveform at the instructed frequency before acting. Each switch has a different purpose, and a rushed response can help the wrong caller.
