Changes to our Privacy Policy
Any changes to the collection and use of personal information as a result of upgrades to this application will be disclosed on this page as appropriate.
1.0.1 (2026.8.22)
- [Change] To apply only the tags to the original file without making any cuts, we’ve added a “Save to File” button to the tag editing screen.
- [Change] You can now drag and drop image files into the artwork section of the tag editing screen to add them.
- [Update] Just to be safe, I’ve also added an English localization.
1.0.2 (2026.8.27)
- [New] We’ve added a “Lyrics” field to the tag editing screen.
1.0.3 (2026.8.26)
- [New] We’ve added “Check for updates at startup” to the settings.
1.0.4 (2026.8.29)—[Xcode 26.6]
- [New] You can now apply normalization to the entire audio file.
- [Fixed] We have fixed a bug where, once the Settings window was opened, even if you closed it afterward, clicking the Dock icon while the main window was closed would open not only the main window but also the Settings window.
1.0.5 (2026.9.1 Submit—Under Review)
- [Change] We have switched to publishing on the Mac App Store.
- [Fix] We fixed an issue where, when zooming in on a waveform and attempting to select a range to cut with the mouse, the screen would not scroll if the selection reached the edge of the screen while dragging.
