Voice Shaper is a speech pre-processor for SSB transceivers. It receives the voice signal from the microphone connected to the soundcard, and sends the processed audio back to the soundcard in real time. The following processing functions are implemented in the program: Bandpass filter; 7-band equalizer;
Noise gate;
Compressor;
RF envelope clipper.
The configuration procedure of the DSP functions is interactive: the program records your voice, then it plays the recording back through the processor and allows you to adjust the settings and immediately hear the effect of your changes. Real-time spectrum and histogram displays provide the insight into the processor operation and make the configuration process even easier.
