Hi,
I am trying to stretch the information in an audio block.
i.e.,
Original: a, b, c, d, e, ... , N (where N is the block size - 1)
Modified: a, 0 , b, 0, c, ... , N/2 (later half of the original block can be trashed)
The target of the manipulation is the output of [rfft~] Are there any efficient ways of such manipulations at audio rate?
BTW, I've lately been enjoying playing with the output of [rfft~] and would also appreciate pointers to resources discussing pitch manipulation using [rfft~] and [z~] or similar concepts not limited to Pd. Not quite sure what term referrers to this method.
Thanks.
