Hello, I am attempting some basic convolution of two sound files.

For some reason I get a funny error message...sfplay~ : no open file

but it seems to work ok. I just wonder if I'm not missing something here.

Thanks for taking a look. Any tips or suggestions are very greatly appreciated.

Is this how you'd go about it?

actually you're not making a convolution, but just a ring modulation, a multiplication of the two signals in time domain. In order to do a convolution, you have to make this multiplication in frequency domain. take a look at the fft tutorials, there is also one convolution patch in the folder examples, in max folder.

I think the patch is ok, you get the message if you begin before opening the two files, otherwise it should work without error messages.
