[PD] AM by keeping the Carrier (Not Ring Mod)

[Arda Eden]

Hi,
Most of the AM examples are simply multiplying carrier and modulator outputs, which is also known as Ring Modulation. But in the resulting spectrum the carrier is gone and only the side bands appear. I couldn’t figure out a way to keep the carrier signal in the resulting spectrum (Like as in real AM, not RM).

It was easy in Csound for example, since the amplitude value is an input parameter to the oscil function.

Any ideas ?
Thanks.
