From: jungledmnc on 18 May 2010 04:09 Hi there, I'm using an interpolated delay line size for audio effects such as flanger or vibrato. The trouble comes, when I want to change the delay line size. So far it seems the only way is to "stretch" the entire delay line to avoid abrupt edges that would be caused by jumping allover the line. But this works with cubic interpolation, but not with sinc interpolation, which generates the abrupt edges and thus zipper noise (for obvious reasons). Any ideas how to solve this? Thanks in advance. |
