I upgraded Windows Audacity from version 2.4.2 to 3.0.2, and have two questions on the project files saved by these two versions.
(1) Audacity version 3.0.2 project file is saved as *.aup3 while version 2.4.2’s project file is *.aup. Why does 3.0.2 use different project file extension?
(2) Project file size of Audacity 3.0.2 is much larger than 2.4.2’s (87 MB vs. 160 KB) for the same project. Why they have such big difference?
Thanks & regards,
