Hi Everyone,
all the best for the new year etc...
Perhaps this is an idea to improve the Short/Long block switching:
When would you probably want to switch from long to short blocks? Probably when 'the
amount of pure sinusoids' is low... in other words, when the signal is kind of noisy.
Wouldn't it make sense to use a spectral flatness measure; not necessarily the one
in the MPEG standard for a detection of switching? An idea would be: filter the
signal/mask ratio, determine the difference between this ratio and the unfiltered one
and switch whenever the difference is larger than ...!
