can't normalize

hello everyone,
i’ve tried to normalize my tracks, sometimes it works, sometimes it makes my PC bugging and i have to restart. has anyone the same problem?
i use Ardour 5.4 …

up !!! same with 5.5

Can you describe exactly what settings you are using and what fails.

hi mhartzel,
i just try to normalize an audio track recording my voice.
i right click on my track, i go to the track menu, then i go to gain then normalize.
it makes my pc crashing. i’ve got no settings but the ones pre-configured.
