this is Alberto's example:
 soundfiles = soundfilenames.collect({ arg filename;
  var path, file;
         path = foldername ++ filename;

        file = SoundFile.new;
   if (file.readHeader(path) and: {  file.preload; },
              { file },
                       // complain if file is missing:
                 {       "WARNING! File:" + path + "not found!").postcln;
                        nil

it makes sense, but I just can't get it to work.
I get an error "readHeader primitive failed - path not
string"

For each sound file I'm playing in my patch, I need to
call the file's length.  I can't read the sound file

do

path.dump;

       

right before you do

file.readHeader(path);

so you see what path is at that time.

I tried making path a symbol to make it fail,

s = SoundFile.new;

s.readHeader('blablabla...');

and the error window then reads:

ERROR:
Primitive '_ReadSoundFileHeader' failed.

Wrong type.
RECEIVER:
   false
CALL STACK:
   Object::primitiveFailed
        arg this = false
        SoundFile::prReadHeader
        arg this = false
                arg pathName = 'blablabla...'

                // so pathname is a symbol, not a string.
       SoundFile::readHeader

hope that helps,

best,

adc
