My dad has the test version of Audio Cleaning Lab installed. I found out that the version is 22 (from the folder where it was installed). But I can't buy a license for Audio Cleaning Lab 22, only for years like 2016, 2017, ...
@stevemaster I think version 22 was the last version before the software was renamed to Sound Forge Audio Cleaning Lab. So it should be Audio Cleaning Lab 2017. I would suggest for you to test the newest version Sound Forge Audio Cleaning Lab 4. If I remember it correctly, the older versions of ACL have problems running on newer Windows 10 versions. Magix doesn't sell version 2017 anymore. If you buy it somewhere it is likely some leftover stock.
