Re: [chuck-users] SndBuf functions - valueAt ??

hi spencer i'd really love to see come clearer docs on sndbuf myself:) i havent touched chuck since that last little issue i had with it. i do miss chuck. but i want to learn to sample with it. not really much of a synth fanatic. i sample my synths then throw them into my sampler :) Spencer Salazar wrote:

Hi Laurie, Its not documented but SndBuf.valueAt() actually takes an integer argument, which is the buffer position of the sample you are trying to take the value of. So a.valueAt( a.pos ) will give you the sample at the current buffer position. Also, it returns a float. Im not sure why it is documented like it is on the website; we'll be sure to make the docs more clear on that soon.

I see the following functions in the Chuck manual, for SndBuf: .read - (string, WRITE only) - loads file for reading .chunks - (int, READ/WRITE) - size of chunk (# of frames) to read on-demand; 0 implies entire file, default; must be set before reading to take effect. .write - (string, WRITE only) - loads a file for writing (or not) .pos - (int, READ/WRITE) - set position (0

I am now trying to use the .valueAt function, but am getting errors. The program is something like.... SndBuf a ; ...etc I read a soundfile into sndbuf a and play it - that much works....

int samp_pos ; float samp_val ; for (0 => int j ; j < 10000 ; j++) { j => a.pos ; j => samp_pos ; a.valueAt() => samp_val ; // <<>> ; // <<< samp_pos, samp_val >>> ; }

Here's the error message: [trigplay2calc.ck]:line(151): arguments type(s) do not match: [trigplay2calc.ck]:line(151): ... for function 'SndBuf.valueAt (...)' ... [trigplay2calc.ck]:line(151): ...(please check the argument types)

When I change the type of samp_val to int, I get the same message. When I leave out the parentheses, it complains that it's a function.

Does the .valueAt function work?

Thank you!
