The problem I describe concerns projects with audio events only.
The internal file format is 32-bit. The OS is Windows 7 32-bit.
The sound interface is RME Multiface II. All sound files used
were also recorded on this computer and with Podium 3.3.3 and
in the same projects.
I edit takes in a component track with several child tracks to
create one single sound event for the component track. During
editing I create various types of fades in and out (-12dB and
-20dB) to remove background noise, crossfades where sound events
overlap (mostly -3dB and linear) and move the duplicates on the
component track along the timeline. Then I mark all of them and
execute a merge.
The resulting sound event does not contain the fades and
crossfades. The clicking noises are visible in the sound event and
show that two sound events are only concatenated, with the
subsequent sound event beginning abruptly.
This 113MB (one-hundred-and-thirteen Megabyte) video shows the
effect with several undos and redos. The beginning is blurred and
it was recorded with an old mobile phone:
