  • $\begingroup$ Thanks, that's very helpful. What does the voice 9 mean, and where should I look at? And do you know is there a way to produce the linear scale instead of the log scale on vertical axis? $\endgroup$ Commented Oct 19, 2013 at 16:37
  • $\begingroup$ Also when right click on the WaveletScalogram and choose coordinates of it, what does the second coordinate stand for? $\endgroup$ Commented Oct 19, 2013 at 19:26
  • $\begingroup$ You should not look for it in the WaveletScalogram - look up the octave and try to localise the signal in time. Voice is just the the second coordinate from the pair (octave, voice). Wavelet transform constructs those pairs and then assigns them a scale and each scale represents a vector containing wavelet coefficients. See "wavelet vector coefficients" in your post - that's them :) Well, bear in mind that we are using a -Log scale and the numbers you see are not reversed and the logarithm of them not taken. $\endgroup$ Commented Oct 19, 2013 at 21:32
  • $\begingroup$ A reason for the down vote ? $\endgroup$ Commented Nov 18, 2013 at 16:32

    $\begingroup$ To whomever downvoted the answer -- care to explain the reason behind it, so that I can improve my answers in the future ? $\endgroup$ Commented Aug 27, 2015 at 7:10
