Given a ridge \(\phi\) (for the wavelet transform), returns a (appropriately) subsampled version with a given subsampling rate.
wRidgeSampling(phi, compr, nvoice)
ridge (1D array).
subsampling rate for the ridge.
number of voices per octave.
Returns a list containing the discrete values of the ridge.
time coordinates of the ridge samples.
scale coordinates of the ridge samples.
number of nodes of the ridge samples.
To account for the variable sizes of wavelets, the sampling rate of a wavelet ridge is not uniform, and is proportional to the scale.
