The app bundles the local processing engine, so\nnormal use is just download, install, prepare, preview, and transfer.\n\n## What It Does\n\n- Prepares regular songs or existing four-stem folders.\n- Creates SP-1-ready WAVs: 24-bit, 48 kHz, eight-channel PCM.\n- Keeps prepared tracks organized in a Library view.\n- Plays master and individual stem previews inside the app.\n- Transfers ready albums to the SP-1 over USB-C.\n- Shows connection state, transfer status, confirmed progress, and recovery details.\n\n## Download\n\nThe app download is in [Releases](https://github.com/JT-Apps/SP-1-Utility/releases).\n\nDownload `SP-1 Utility.dmg`, open it, drag **SP-1 Utility** into\n**Applications**, then launch it from Applications.\n\nThe DMG is attached to the release instead of the Code tab because it is too\nlarge for normal GitHub repository files.\n\n## Three Simple Functions\n\n### Prepare\n\nAdd songs or four-stem folders, set BPM, and create SP-1-ready output.\n\n![Prepare screen](assets/screenshots/prepare.png)\n\n### Library\n\nReview prepared tracks, play the preview mix, and check individual stems.\n\n![Library screen](assets/screenshots/library.png)\n\n### Upload\n\nBuild an album plan, watch SP-1 live controls, and transfer ready WAVs over USB-C.\n\n![Upload screen](assets/screenshots/upload.png)\n\n## Notes\n\n- Keep the SP-1 plugged in and leave the Mac awake during transfer.\n- Large transfers can take hours.\n- A song is marked Done only after the SP-1 confirms the write sectors.\n- Finder and Quick Look may not play upload WAVs normally because they are\n  eight-channel device files. Use the app's Library preview for normal listening.\n\n## Feedback And Bugs\n\nUse the repository **Issues** tab to report bugs or feedback.\n\nHelpful reports include:\n\n- macOS version.\n- SP-1 Utility version or release date.\n- What you were doing: Prepare, Library, or Upload.\n- Song title and row status, if a song was involved.\n- A screenshot of the transfer panel, if upload was involved.\n\nPlease do not attach copyrighted audio files unless they are necessary and you\nhave permission to share them.\n\n## Credits\n\nSP-1 Utility includes compatibility research and workflow attribution to\n[Solderless](https://solderless.engineering/) and the public\n[SP-1 development wiki](https://github.com/timknapen/SP-1-dev/wiki).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjt-apps%2Fsp-1-utility","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjt-apps%2Fsp-1-utility","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjt-apps%2Fsp-1-utility/lists"}
