[LAU] Linux programs for creatiing/manipulating sound effects

[Mike Cookson]

For non-realtime (including non-linear, like montage) processing you need only plugins (ladspa, lv2, vamp) and some editor like Audacity, mhWaveEdit or something other.
For realtime (also called non-destructive editing... hm, probably, they are right :) you need set of various software, that could be used at one time and be connected each to other).

It would be better for you to begin with special distros, where all necessary staff is installed and has good settings out of box. My favorite is kxstudio, as (imho), best variant  vor newbies.
