Thanks for the reply.
But I already have some litterature about Chowning theory.
The link you pointed at features all useful info to compute
spectrum from carrier & modulator freqs, but what I'm
looking for is the opposite : to determine C & M from
spectrum content...
I was hoping there was some math method (possibly
implemented in some pice of software) for that purpose...

Thanks anyway.
JB
