Abstract
An emulation circuit includes a digital signal processor with a digital filter controlled by frequency response conversion parameters for converting a standard microphone signal into a signal emulating the frequency response of one of a plurality of microphones selected by a selector connected to the digital signal processor. Optionally the conversion parameters can also include phase response conversion parameters. The emulation circuit can be included in a receiver for a wireless microphone or in a microphone itself.
