What format are the filters expecting for audio data?

[tdbarth1]

I am attempting to construct filters for testing, but I am not sure where to get audio data for which to run through the filters and what format the filters expect the data to be in. Any help would be appreciated, thanks!

The format is an array of pointers to data arrays. e.g.
float* a[1]; a[0] = new float[44410]; //filter setup process(a,44410);
"a" can have more elements, each pointing to a different array. The filter will treat each of them as separate channels. The audio data goes into the "new" array.
