REAPER SRC Test

Being new to REAPER 2.104 i wanted to test the sample rate conversion quality & compare it to other DAW solutions. It holds up very well. I will have no problem using REAPERS "Extreme" SRC settings for my conversion needs.

I went to http://src.infinitewave.ca/ for my comparison.

The Test

Up sampled 32bit/44100 sweep & 1k tone. As well as Down sampled 96000 to 44100



Setting Options


Unaltered 44100 1k control


1k 44100 to 96000 Fast (16pt Sinc)


1k 44100 to 96000 Fast (IIR + Linear Interpolation)


1k 44100 to 96000 Fast (IIRx2 + Linear Interpolation)


1k 44100 to 96000 Lowest (Point Sampling)


1k 44100 to 96000 Low (Linear Interpolation)


1k 44100 to 96000 Good (64pt Sinc)


1k 44100 to 96000 Better (192pt Sinc - SLOW)


1k 44100 to 96000 Best (384pt Sinc - VERY SLOW)


1k 44100 to 96000 Extreme (512pt HQ Sinc - NON-REALTIME)
