Hi Jean-Marc, Thanks for taking a look. I've added an example program in the patches that changes the rate frequently. You can run test-resample2 >test.raw and open in audacity or so to look at the spectrum etc. I've attached a before/after screenshot. In theory, depending on the current phase and the rate changes that are applied, the error can be audible as a pop when changing rates. I've tested this with a sine wave, it might...

Hi, These patches improve the resampler set_rate function. The first 2 patches do some cleanups in the GCD calculation and avoid an overflow when calculating the new phase. This patch could probably be simplified if we allowed 64bits operations in speexdsp. The 3rd patch avoid rounding errors in the phase calculation. The problem is that the new rate is calculated with the reduced rate, which

Hi, I have used this command : resamples<-lapply(1:1000,function(i) sample(lambs,replace=F)) resamples2<-lapply(resamples,Cusum) to get a list of 1000 samples of my data. The function Cumsum is defined as follows: Cusum<-function(x){ SUM<-cumsum(x)-(1:length(x))*mean(x) min<-min(cumsum(x)-(1:length(x))*mean(x)) max<-max(cumsum(x)-(1:length(x))*mean(x)) diff<-max-min
