Well the idea is that audio blocks are stored a bit differently then say
vertices. in the case of vertices, a hole is an array is just a non
existing vertex, a polygon referencing to that vertex is a non-valid
polygon. But when it comes to audio, a non set block is a silent portion
of the audio track. It can be played and used, you just wont hear it. so
if you habe a audio layer with 3 blocks set and clear the middle one, the
layer doesnt get shorter, it just gets a silent portion in the middle.
Actiually, the layer always have infinit length its just that most of it
is silent.

Does the naming make more sence now?
