Re: [PD] convolution code error

hi,

i think the error is to harcode the size of arrays to 255.

in fact, arrays in1 and in2 are of the size of the n variable passed to the perform routine and this variable is 64 by default ( the default block size ).

for(set=0; set<n; set++)

cheers,

here is the code for my convolution project that i'm working on. i

sent an earlier email to the pdlist, but i don't think it'll go through because it's over 2MB which includes a bin file. anyway i found out where i'm getting the seg fault:

for(set=0; set<=255; set++)
{
    aleftout[set]=(*in1++);  /*brings in 256 samples from input*/
    arightout[set]=(*in2++);
}

what i think is happening is that aleftout and arightout are float arrays, and what i'm trying to pass into them are pointers to floats. everything in my code is happening in the while(n--) part of it, so i think i just need to make some type conversions there. i believe all of the fftr4_ functions take floats, so i need to convert from pointer to float, and then again from float to pointer. thanks in advance to anybody who can help me! i'm just not sure how to do this.
