SOUNDCHECK DOWNLOAD PACKAGE

Mac preview 0.4.0: unzip SoundCheck-Mac-0.4.0.zip and move SoundCheck.app to Applications. This development preview is Developer ID signed; Apple notarization is not yet available. macOS may block downloaded previews. Source is included if you prefer to build locally.

iPhone and iPad 0.4.4: open SoundCheck-0.4.4-Source.zip on a Mac, open the Xcode project, choose your own signing team and bundle IDs, then build onto your connected device. This is not a direct iOS installer. Public App Store/TestFlight distribution is not available yet.

Known limits: Mac Music and virtual output routing need further testing; physical audio-interface mapping and acoustic calibration remain unverified. Apple Music uses device volume and its own protected playback path.
