doepfer a-129-5 voiced/unvoiced detector (vocoder subsytem) price : $99.00

the voiced / unvoiced detector (a-129-5) can recognise voiced and unvoiced sections in the speech signal, and switch the carrier signal accordingly. the incoming speech signal is processed through a pre-amplifier with adjustable gain and a treble boost unit. the treble boost improves the vocoder effect.



the voiced/unvoiced recognition system controls a voltage controlled switch (like a-150) which is used to switch between the voiced and unvoiced carrier signal (e.g. vco and noise). additionally the voiced/unvoiced information is available a a gate signal. a led displays the unvoiced state.
