There are 27 different sound samples in this pack, ranging from short to long. They come "dry", so you will have to add your own reverb and delay as you use the sounds over the music.
As said, they are all created with the free VST plugin offered by the (again, excellent) INTERRUPTOR.ch website. There are, however, certain programs which will not work properly with the plug in and there are several programs and situations that will not let you work with VST so for those instances this first volume of "Dubroom Dub Siren" will serve just well.
