Overlap add method and overlap save method are block processing technique. Input data gets divided into smaller chunks on which convolution is performed to find output. The overlapped portion is discarded in OSM whereas it is added in OAM to get requird output. In the C code convolution of blocks is performed by using FFT.
Linear convolution is used in OAM method.
ReplyDeleteOSM is preferred over OAM
ReplyDeleteBecause the osm is faster hence efficiency is improved.
DeleteNice.
