Audiospektri Introduces the PGV

Adding to the company’s line of cutting-edge digital synthesizers, Audiospektri has unleashed a new digital effect stompbox – the PGV or Parametric Guitar Vocoder. It expands the capabilities of traditional vocoders by deep analysis of the guitar signal that controls the voice synthesis.

​A typical guitar vocoder modulates the guitar signal spectrum with the spectrum of the vocal singer. The new PGV instead first measures the pitch and amplitude of each of the six strings. When these parameters are analyzed, the synthesizer can build clean voices that follow the singer's voice – or add various special effects to the parameters for more fun. The PGV is available in three forms, A studio version, a smaller gig stompbox, and a modular Eurorack version.

The gig pedal stompbox offers the following features:

• Spectrum shift for voice manipulation from “baby” to “giant” voice
• Vibrato, pitch bend, and VCF
• A pilot signal for synthesis without the vocal, adds also FM synthesis
• Transpose, spectrum freeze, and distortion-free compressors
• True bypass on/off switch
• 9-volt operation and standard DC input
• The larger studio version has also noise synthesis and balanced stereo outputs.
