actually it turns out my weird results are due to the fact that the
files have a different sample rate than my setup (ie files 44.1, ChucK
48kHz).
I'll keep looking into it later on and give an update here :)

Hi Mario , I’m not at my computer right now, but wonder if you’ve
tried SndBuf2?

Hi,
I'm working on an algorithm that requires accessing samples from a
stereo file and am using SndBuf to achieve that.
I was expecting that to work so that samples were returned in
"frames",
for example:
'''
buffer.valueAt(0) = sample 0 on left channel
buffer.valueAt(1) = sample 0 on right channel
buffer.valueAt(2) = sample 1 on left channel
buffer.valueAt(3) = sample 1 on right channel
...
'''
but that doesn't seem to be the case.
Also SndBuf.samples() always returns the same amount of samples,
regardless the file being mono or stereo (the size matches the
time in
msec, so it seems that reports the size of a single channel).
I also played around with .channel(n), but I get the same set of
samples
regardless the channel number used.
Then I just now found out that basically the channels seem to be
stored
(or at least accessed) sequentially.
Let's say you have a stereo file containing 1024 samples (512 per
channel), you get:
samples 0-511 = left channel
samples 512-1023 = right channel
I was wondering if my assumption is correct, but also if this is
intentional.
Cheers,
Mario
