[PD] readsf~ help question

[José de Abreu]

if you just use [open ../sound/bell.aiff( it will play just as dan said, a
mono file only on the first channel.

when you use [open ../sound/bell.aiff 0 200 4 2 b, 1(, also as dan said,
you are forcing the format as which readsf~ will read the file, using the
arguments just as the  -raw argument for the [soundfiler] object, so

0 means onset
200 means header size to skip
4 means number of channels (!!, you are asking for 4 channels here)
2 means number of bytes per channel
b means big endian

since you asked for 4 channels, you will get interleaved samples for each
channel, hence the pitch up, since you are feeding 4 samples at once from
the file to feed each channel, if the original is mono, you get 4x faster
