Abstract:
A signal processor, comprising:an input for receiving an audio data signal conveying speech sound information; an output; a signal converter coupled to said input for processing the audio data signal at said input, said signal converter capable to selectively acquire a first operative mode and a second operative mode, in said first operative mode said signal converter converting the audio data signal from a first format to a second format and releasing the audio data signal in said second format from said output, in said second operative mode said signal converter permitting passage of the audio data signal to said output without conversion to said second format; a control unit coupled to said signal converter for controlling the operative mode of said signal converter, said control unit being responsive to a first control signal to enable said signal converter to switch from said first operative mode to said second operative mode, said first control signal being indicative that the signal processor is in communicative relationship with a remote signal processor capable to operate in either one of said first and second operative modes, said control unit being further responsive to a second control signal representative of a type of speech activity in the audio data signal to prevent said signal converter from switching from said first operative mode to said second operative mode.
