Just downloaded Audacity 4 beta. I use Audacity to record podcast episodes. When I hit pause recording, the recording pauses. I am unable to start it back up. I just stop it and restart.
I also noticed the meta data that I filled out for the mp3 file did not save when I exported the file. I tried with three different files. It did however save on the WAV file.
For what I use Audacity for Audacity 4 looks nice and so far plays well.
