- Page 1 PGV manual The Eurorack module version PGV is a registered trademark of Audiospektri Finland Oy...
- Page 2 The abbreviation PGV stands for Parametric Guitar Vocoder denoting the difference from a traditional vocoder that merely modulates the guitar signal based on the vocal spectrum. The PGV instead does an analysis of the guitar signal, and measures the pitch and amplitude of all the individual strings. Based on that data, the PGV does independent synthesis for all the found six string signals, based solely on the vocal spectrum, and allowing controlled modification of the analyzed parameters.
- Page 3 The use of the I/O signal and compressor controls Because the output signal of the PGV has to be a sensible combination of both the vocal microphone and the six guitar string signals that all have a wide dynamic range, signal compression is a critical part of the PGV software.
- Page 4 The frequency resolution and latency are tied together: higher resolution inevitably means longer latency and vice versa. Therefore we have tried to achieve a good tradeoff between an acceptable latency and good enough note discrimination resolution. The limitations are described in more detail in a separate document ”PGV explained” in the website www.audiospektri.com.
