Hello Markus & Co.,
1. That would be great indeed to be able to automatically superpose
curves from different audio files using different colours. The problem
is that this would not work in general: for instance, if we compute now
a frame-decomposed chromagram using the 'frame' option, each data is
represented by a 2D fully coloured matrix, not suitable for
superposition. So either you follow Dmitry's advice for your particular
case, or you can also dock all your figures and use Matlab built-in
interface to align and compare your figures. For instance, to have all
figures always docked:
set(0,'DefaultFigureWindowStyle','docked')
(This can be added to your startup.m)
2. I am not sure to understand what those "hidden" letters look like
exactly. Maybe it is a Matlab version or platform-related problem? The
figures in the manual were obtained using the Mac-version Matlab 7.5.
What is your configuration?
Kind regards,
Olivier

1. data1 = mirgetdata(mirchromagram('ceg_a3.wav'))data2 = mirgetdata(
mirchromagram('ks-A4.wav'))
You get matrixes which can be plotted manually.
