Problems with Filter Application

[MU Speech Lab]

I've gotten almost all of my filters to work, except for one. I
continue to get this error.


MESSAGE:

Error using ==> set_form
We can't set to desired form, skeletons don't match.

Please let me know the best way to diagnose it. Thank you.

Hello,

I think this is the key. The signal filter API expects the 'compute'
function to process 'samples' and produce 'filtered samples'. There is
a one to one correspondence between these. The samples come in as one
column per channel. The output should have the same shape.

I know that the one to one correspondence is not perfect and it
typically produces 'edge effects', this is the state of the API in the
preview version and it is not clear that it will change.

Hope this helps,

Harold
