Cubase’s very own “Standard - Drums” and “Standard - Vocals” time-stretch algorithms saved the day.
I tried multiple algorithms on drums, including Wavelab’s, and another more fancy one from a dedicated app (I can’t remember the name), and Izotope’s time-stretch in RX… and Elastique pro and MPEX… but none of them could get the transient to sound clean and natural like Cubase’s standard - drums.
And oddly enough, the same thing held true for my lead vocal track. Noticeable artifacts until I turned on Cubase’s Standard - Vocals algo.
There’s nothing standard about them. I never realized this. They are “pro”.
I listened to all the different algorithms by putting different audio material in a project. Then I stretched audio events with the time stretch tool (not the offline process). In the end I switched through the algorithms (through the field in the Info Bar).
Very revealing.
I like to keep an open mind, ie. if an algorithm is not suited for natural sounding changes I might be able to use it for sound shaping/altering.
Even Drums mode has an issue, and that is timing is not as correct so be aware of that it will interduce lots of phase problems when stacked and with other sounds which is going to lead to the endless mixing.
