Hello Archer,
The SPECNU programs appear to be working (on PC) -- note that they take analysis files as inputs. The command line example given for SPECNU RAND is incorrect: it is missing out the flags. It should read: specnu rand inanalysisfile outanalysisfile -t0.5 -g50. Smaller values for -g gives a more granular-like textured result. More info in a day or two.
I'm using the cdp tool in Renoise where an audio file is automatically converted to an .ana file using pvoc under the hood, send to the input of a fft process like specnu rand and its output .ana also automatically converted back to .wav (usually
. As far as I can tell from the terminal in Renoise, an .ana file is made from the audio input, but after sending it to specnu rand, nothing happens, like it is being picky on what .ana it accepts? Will try running the processes from the commandline to see if they do work there.
