I recentlyn installed Audacity 3.0.0 and have two problems:
When I used 2.4.2 and saved an edited music file it appeared on my desktop from where I placed it in the appropriate music file. With the latest version I don’t seem to have any control over where that file is saved but it is saved to Documents and I can not always place it in the appropriate file - it just won’t move. It will eventually move but only after a few tries.
when I was using the older version the edited files played with a uniform volume. Now there is a brief (a few seconds) at the beginning of the recording where the volume is higher before the rest of the recording volume fades. I am not certain this is solely due to the change to the most recent version of Audacity, but I have only it since installing the new version.
