Yesterday I published a post about aliasing in amp simulation in Reason and the oversampling techniques with are used to prevent it from generating annoying aliasing effects. Today I want to focus on Ableton Live. Unfortunately Live doesn’t over oversampling modes for Softube Amp and it’s Overdrive device. Kinda strange because the Softube Amp rack extension in Reason won’t generate aliasing artefacts while in Live they will! Softube Amp in Live uses totally different Amp and Cabinet algorithms compared to those used in Reason. To make a long story short: Softube Amp in Reason sounds great while in Ableton Live it sounds like shit. An update in Live for Amp and Cabinet is most wanted!
Here are the sound examples I made with Live. It’s a bit annoying to listen to these tracks ’cause I am bending the high e-string of my guitar in such a way so you can hear the aliasing which is going on. Aliasing artefacts all over the place:
P.S. these tests are done using a sample rate of 44.1 kHz. Sometimes I use 48 kHz for video projects.
Update: the Saturation and Dynamic Tube devices have Hi-Quality modes (right-click on the title-bar of these devices to activate it) which are using oversampling techniques to prevent aliasing.
