Hi,

I try to send thispart of code :
Code:

// The speaker positions [eleveation],[azimuth]

e = [90,40,40,40,40,0,0,0,0,0,0,0,-40,-40,-40,-40];

a = [0,45,135,225,315,25,75,130,180,230,285,335,0,90,180,270];



// adjust your path to the Kemar data

// this is relative to the SC3 folder

Kemar.path = "KemarHRTF/"

Kemar.initBuffers(a, e);


and I get this result :
Code:

ERROR: Primitive '_FileLength' failed.
Failed.
RECEIVER:

  instance variables [1]
    fileptr : nil

      arg this = <instance>


I have downloaded Kemar at this adress :
http://sound.media.mit.edu/resources/KEMAR.html

and put my folder KemarHRTF/ in my SuperCollider folder app that i can see with this :
Code:
Platform.userAppSupportDir


But maybe i forget something... I have copied all .dat from Kemar/full/elev0... to Kemar/

??

what's wrong?
somebody know?
thanks...

Code:
RECEIVER:
Instance of File {    (B75EDB70, gc=44, fmt=00, flg=00, set=01)
  instance variables [1]
    fileptr : nil
}


Since fileptr in the File is nil, the OS could not open the file. Possibly a wrong path?

I haven't used these classes, not sure exactly how to fix it - but I can say for sure the "FileLength failed" error is because the file is not open.
