Adding a metalic feeling to any voice to make it sound like a robot is easy.
Of course if you want the extra funkyness you can use a vocoder plugin in Wavosaur
But to change your voice into a nice robot (not a bad robot, this will be for a next tutorial), just 2 or 3 clicks are necessary :
For simpler & faster results, you can use amplitude modulation
How to sound like a robot ?
1) launch Wavosaur and load a voice sample
2) go to Menu Tools -> Synthesis -> Simple
Synthesis tool menu
3) now use these values for the parameters :
– Frequency : 75 Hz
– Type : Sinus
– Volume : 0 dB
– Apply : “Apply on all current file” OR “Apply only on selection” if you just want to robotize a selection you made on your file
– Advanced : Multiply with audio file – this is the most important! this is the Amplitude modulation! –
Synthesis tool
4) click the “OK” button
Now you should have results like this :
extra bonus more plus (gating) :
Of course you can try other values for the frequency, if you select low frequency values (under 20 Hz), you start to have a tremolo effect, or gate effect if you change the waveform to abs square
but the synthesis tool is not well suited for gate effect, for that, there is the gapper effect
go to Menu Effect -> Gapper
Gate me !
Now you can select smoother waveforms for gating your file (and apply fade in/out to prevent click noises)
