| I have been experimenting a little with this. The paulstretch opcode does not allow for transposition so the idea here is to transpose using diskin & write to a table (2 actually as file is stereo) and have the tables read by paulstretch.
All seems fine using tablewa, which I accidentally stumbled across (and don't completely comprehend; I'm actually surprised I got this to work...) . However my initial attempt using tablew, based upon example 03D07 of the FLOSS manual, produces no sound. I'd like to understand why one works & the other does not. Also, why does tablewa seem to automatically sequentially write to different idx whereas with tablew it would appear that it is recommended to use a phasor or other method?
I'm very new to writing audio to tables so please forgive my apparant complete ignorance here.
And if there are obvious ways to achieve these results in a better way feel free to offer suggestions.
Here are the two examples:
instr 1
iRand = random(-12, 12.99)
iFreq = semitone(int(iRand))
print iFreq
aSf1, aSf2 diskin2 "cello1.wav", iFreq, 0, 1
iLen filelen "cello1.wav"
print iLen
iLen2 = (iLen * sr)/iFreq
print iLen2
giL ftgen 0, 0, -iLen2, -2, 0
giR ftgen 0, 0, -iLen2, -2, 0
kstart = 0
kstart tablewa giL, aSf1, 0
kstart tablewa giR, aSf2, 0
aL paulstretch 30, 0.2, giL
aR paulstretch 30, 0.2, giR
outs aL*2, aL*2
kTime times
printk 5, kTime
endin

Here are the two csd & cello1.wav files in case it makes it easier to examine:
