We've got signal, but what the heck is it?
That's your mission. Analyze this bébé.
download the audio file 15.wav.bz2
hints :
-
No need to bunzip2 this file since baudline can automatically uncompress
bzip2 files.
-
Setup baudline to be a Web Browser helper application as described in the
FAQ.
-
Listen to the whole 11 second audio file because there are a number of
different clinks, clunks, and dings. Notice how the cadence changes.
-
Slow down the audio with the
Play Deck's speed control
and listen for sonic details that would otherwise be missed.
-
Use the
Color Aperture
window to focus and maximize the color resolution. An upper -20 dB and
lower -110 dB range is a good starting point.
-
Use the Kaiser or Gaussian
windows with a high beta
value to improve the time resolution in the spectrogram display.
-
Use the
periodicity bars to make
an accurate time measurement between the clicks. How constant and
repetitive is the mystery signal?
What is it?
