Stempel Spectral Vocoder v.1.0
Stempel, spectral vocoder VST effect plug-in for Windows.
Contrary to many other vocoder, it’s not processing in the analog way (using band pass filters and signal followers) but in the frequency domain (in opposite to the time domain). In the frequency domain the sound representation is no more ‘amplitude versus time’ but rather a bank of complex numbers representing the magnitude and the angle of each frequency component present in a small time domain buffer.
Stempel operates with these complex numbers to reproduce the vocoder effect and then transform them back into time domain samples.
Two additional time domain effects can be applied to the vocoder:
– A saturator using the ‘variable parabolic’ shape – A standard chorus with a good quality delay object.
