Spectravox | Traditional Vocoding & Vocoder Processing


video upload by Moog Music

"In this video we explore how to use Spectravox in Vocoder mode to process vocals.
We begin by hooking up a dynamic microphone (in this case the Shure SM58) to the program input and adjusting the preamplifier gain to an appropriate level. This allows us to create classic analog vocoder sounds with our voice and Spectravox’s internal carrier oscillator and white noise generator. We next look at how to use the program envelope follower and an attenuator to increase the intelligibility of Spectravox and capture the dynamics of our voice. Finally, we connect Matriarch to the carrier input of Spectravox to be able to vocode chords and polyphonic material with our voice."

"In this video we explore how to use Spectravox in Vocoder mode to vocode a drum machine.

By using a drum machine (in this video the Roland TR-606) in place of a microphone as the program input to a vocoder, we can map the rhythmic and tonal information of that drum machine on to Spectravox’s carrier oscillator and white noise generator. Spectravox’s Spectral Shift function allows you to move all of the filters up and down while resonance will impart more colorful and metallic tones. In this video we look further at how to use the filter bank patch bay to rearrange the envelope follower outputs and control voltage inputs of the two filter banks inside Spectravox to scramble the frequency spectrum. We also look at how all those inputs and outputs can be combined with the additional patch points on Spectravox for creative and interesting modulation."
