Hissing problem with buffer in sampler

December 12, 2012 | 1:31 pm

Hi,

I’m making an attempt on creating a sampler to use as a plugin in Max For Live.

The sampler is built around the "free elastic" work by Devin Kerr. ( http://www.devinkerr.com/2008/10/30/free_elastic-independent-pitchspeed-control-in-max/) Thanks Devin!

And the problem I have is with a hissing noise when I play my samples through the groove objects. I haven’t had any problems like this before, and am using the same setup (specified below). I would be very grateful for any input on this problem!!!

I’m including a small aiff file. But the problem stays with other audio clips as well.

And – the file will only work if you keep the attached "fft.maxpat" in the same folder as the patch itself.

The problem seems to come from my buffer having bad format of the lenght of the sample and/or channels.

Now I’m sending buffer an aiff.-file via a message with "import $1 0. -1." And this results in the hissing noise over the aiff.-file.

But if I just send the .aiff-file via a message with "read $1" buffer works without the hissing sound. How should I format the "import"-message? I want to be able to use it to be able to send a .mov-file to buffer…
