hints :

  • Setup baudline to be a Netscape helper application as described in the FAQ.
  • Turn on the 60 Hz notch filter in the play deck.
  • Try playing the mystery signal at different speeds, slow it down or drop it an octave.
  • Use baudline's harmonic helper bars and delta measurement bars to determine the harmonic relationships.
  • How many main events are happening? Do they seem repetitive?
