The problem seems to be the "speed" effect, which implies a "rate" effect, which uses ffts and thus the zero from the pad effect may become nonzero (but close to). My suggestion is to either use "speed" on sound0000 and generate an intermediate file or to explicitely use the "rate" effect _before_ "pad" (but I'm not sure, the latter works). cheers, Erich On 27.09.2016 22:55, Bob S wrote: > Hey Erich, I don=92t know if you saw my post =97 sorry to bother you bu= t I am wondering you see anything wrong with the way I am calling sox her= e? >=20 >> Hey Erich, >> >> Thanks again for the reply.
