I now i’m trying to use generalized cross synthesis with AS but when i’m chosing
the dynamic type of crossing between two sounds i have to select a parameter file
for the transition.
My problems is that i don’t know how to write the parameter file.
I tried to use some example in the handbook that i found on the web
but when i’m checking the parameter in the dialog box the software report an error: “the first line does not contain floating points”
Someone can help me?
thank you

Hi Lorenzo,
The parameter file is different for “add” and “cross” modes.
For cross mode the file is made of lines with:
time X x Y y q
For add mode the file is made of lines with:
time X x
Ensure you have a proper delimiter between each parameters in a single line. The delimiter can be a TAB or a SPACE.
let's take a simple cross-synthesis in cross mode starting at the beginning of the file (time 0) :
the SuperVP command that AudioSculpt will produce for a constant cross synthesis may look close to the following command line : notice here the parameter values beginning after -X -x -Y -y -q.
supervp -t -Z -norm -S"/Volumes/Data/cp/as-sounds/tenor.aif" -s"/Volumes/Data/cp/as-sounds/noise.aif" -M0.0928798019886017s -m0.0928798019886017s -oversamp 8 -i512 -Wblackman -wblackman -Afft -afft -N4096 -Gcross -X0.67 -x0.33 -Y1 -y1 -q1 -cross_exp 0.5 "/Users/picasso/Desktop/AudioSculpt 3.1.7/Sounds/tenor-out.aif"
Now if we need to reproduce it as a parameter we will create a simple ASCII text file (warning: do not produce any RTF or DOC) and fill the parameters needed as specified for cross mode : Time X x Y y q.
0 0.67 0.33 1 1 1
you can then add more lines to create changes over time.
NB:
* Use the "Check Parameter File" button in the CrossSynthesis Panel in AudioSculpt (next to the "select" Button) to ensure the parameter seems fine.
* You create an ascii file using TextEdit but you should always ensure that the format used is Text. RTF is the default in TextEdit. For that look in the Format menu, if you see "Convert To Text" then do it.
HTH,
Best,
Charles
