We've got signal, but what the heck is it?
That's your mission.  Analyze this bébé.

download the audio file 7.wav.gz

hints :

  • No need to gunzip this file since baudline can automatically uncompress files.
  • Try playing the mystery signal at different speeds, slow it down or drop it an octave.
  • Use baudline's harmonic helper bars to determine harmonic relationships.
  • Use the delta measurement bars to measure pitch change.
  • Switch to a bigger FFT size to measure small changes in frequency.
  • This is not the sound of a big angry bubble bee.
