You didn't say you needed a digital solution.

Use DSP to generate an FFT of your input signal, then you can do anything you like with the components and reverse the process at the output

Otherwise, a ring modulator does what you want.

Holtek do a standard chip for it. A classic metjod is to use a ringmodulator.
