No, I think what he's doing is raising the sample rate, and interpolating the new samples. For example, double the sample rate, but instead of outputting the same sample twice, you output a sample between the current and the next instead.TmEE co.(TM) wrote:interpolation gives the same effect as lowering sample rate, except for the really intensive methods like sinc and the like

That is exactly what I am doing I have a sample stored at 6000hz and my program will draw a line between the two samples I included the source code in the zip file if anybody is interested in how this all works it is 68kpcm.asm that has the interpolation code.Chilly Willy wrote:No, I think what he's doing is raising the sample rate, and interpolating the new samples.
