I am working on a remake of a 60s song that I was thinking of adding a crackle and pop to.
There's a Click Generator FX Chain in SONAR. However it doesn't process a track, it's a signal generator so you need to mix it in with a track. FX Chains > Anderton Collection > DJ > Click Generator. It doesn't generate hiss, only clicks and pops.
There's also a warped record simulator in the DJ folder where you can choose whether the warp is for a 33-1/3 or 45 RPM record, and the amount of warp.
