[Clam-devel] Default SMS Ana/Synth HopSize

Hi all,

I propose to change the default value for hopsize in both analysis and 
synthesis (this affects some other default configuration values as well).

The rationale behind this is that with a window size of 1024 (for 
residual component) a hop size of 512 is very likely to produce artifacts
as soon as any spectral transformation is applied. The default value 
should therefore be 256. Some time ago I posted something on my
blog related to this issue:
