What's New in Decaud
1.6
October 17, 2026
• Fixed missing album artwork when copying music from iCloud Drive or another folder, including separate cover.jpg and Folder.jpg images. If an album you previously imported is missing its cover, import its original album folder again after updating, using Copy to This iPhone or Copy to This iPad. Updating alone does not restore cover images that were not copied. There is no need to reinstall Decaud. • When selected songs have no readable artwork, Decaud asks for their album folder so the cover can be copied; only the selected songs are imported. • Audio Path no longer shows Bit-perfect when the output's bit depth is unknown, as on a USB DAC; it says the claim is not established. • The Dither setting says the output bit depth is unavailable on iPhone and iPad, so Decaud does not apply dither there. • Audio Path keeps a track's own sample rate after a gapless transition and names any conversion to the output rate. • Tracks without track numbers stay grouped in their album as new music is imported. • Starter Pack rows now indicate the playing track and let you pause or resume it. • On iPhone and iPad, choose whether to remove music from your library or also delete its device copy. • Copying music now identifies files already on this device. • Clearer import and copy feedback, shown until you dismiss it. • Improved iPad status display while navigation panels are open. • Clearer Audio Path explanations on iPhone and iPad. • The Leave a Tip row in Settings is easier to find. • CarPlay Songs opens as an alphabetical list, with Playable Now counts and paging for longer libraries.
