Documentation of programs
« on: March 11, 2017, 06:33:47 PM »
Hi there,

is there any documentation on the cdp shell programs? For example, when I browse through the 'Composers Desktop Project: Tutorial Workshop 1', it's not apparent to me which shell programs are actually invoked. Example:

A. MODIFY SPEED - simple pitch transposition, using semitones
   (SS: Soundfiles > Pitch >Transpose/Speed > semitones)
   (SL: PITCH: SPEED > pitch > tape transpose by semitones)

My guess is this is the `pitch` program, but which mode?

    altharms    octmove    transp    tune    pick    chordf    chord

I.e. where would I find the reference documentation for the pitch program?

Thanks!

Best, .h.h.

Dear HH

unzip the mac documentation from
http://unstablesound.net/downloads/CDPR7Documentation-MAC.zip
and look therein, the SpiralDeskRefR7.pdf should have all algorithms that matter.

Thanks. Still it doesn't really explain the details of the process. If I just throw some parameters at it using my intuition:

$ ./pitch transp 4 '/data/projects/CdpChapter/background/CDPWorkshop1/Worksheets1-5/WS1/CSRCWS01SF01capm.wav' /data/audio_work/foo.aif 0 12
Application doesn't work with this type of infile.

I have no clue why my input is not good. It's a monophonic sound file from the workshop directory...

Ok, getting there

./modify speed 2 '/data/projects/CdpChapter/background/CDPWorkshop1/Worksheets1-5/WS1/CSRCWS01SF01capm.wav' /data/audio_work/foo.aif 12

So SD -- works with phase vocoder files, TD -- works with regular (time domain) files.

Thanks p8rpp, CDPR7Documentation-MAC/doc/html/cgromodf.htm is actually the index I was looking for!
