Hi Dimitris,

in theory, mixing should be exactly what you're doing - the
multiplication of a signal with another one.

Without you posting what your flow graph looks like or what the signal
you get out of it actually is, helping you might be a bit hard...
Please supply as much information as necessary to understand what
might be going wrong ;)


Greetings,
Marcus
