Getting Started with Curlo

Welcome to Curlo — a powerful, privacy-first audio asset manager for macOS that brings fully localized semantic search to your sound library. This guide introduces the five main areas of the interface so you can navigate your workspace with confidence.

The Sidebar on the left side of the window gives you quick access to your entire library structure.

Sidebar — navigate your library, collections, and local folders

It includes the following sections:

  • Built-in Groups
    • All — View every indexed audio file
    • SFX — Browse sound effects only
    • Music — Browse music files only
    • Recently Added — See the latest files added to your library
    • Favorites — Access files you’ve starred
    • Tags — Manage and view all tags
    • UCS Categories — Browse by Universal Category System classification
    • Unknown Types - Browse files that Curlo AI cannot classify as sound effects or music
    • Untagged - Browse files that currently have no tags
    • Unassigned UCS - Browse files that have not yet been assigned a UCS category
  • Collections — Organize files into custom collections (similar to playlists)
  • Local Folders — View the folder tree of your imported directories

The Search Bar sits at the top of the window and supports keyword search, semantic (AI-powered) search, and advanced filtering.

Search Bar — type keywords or natural language to search your library

Asset List

The Asset List is the central panel that displays all matching audio files in a table format.

Asset List — browse and select audio files

Click any file to select it and load it into the Viewer and Inspector panels. You can also use the Up and Down arrow keys to quickly navigate through the list, and click on any column header to sort the files by that specific attribute.

Viewer (Waveform Player)

The Viewer at the bottom of the window shows a detailed, zoomable waveform of the selected audio file.

Viewer — preview, play, and scrub through audio waveforms

Key features of the Viewer:

  • Play / Pause / Back to start — standard transport controls (use Space to toggle play and pause)
  • Waveform scrubbing — click anywhere on the waveform to jump to that position
  • Gesture zooming — use trackpad or mouse gestures to zoom in and out of the waveform for precise viewing
  • Loop toggle — enable looping for continuous playback
  • Volume control — adjust playback volume
  • Snippet selection — select a portion of the waveform to drag into your DAW, bounce to a local folder, or bounce to a collection

Inspector

The Inspector on the right side shows detailed metadata and properties for the currently selected file.

Inspector — view and edit metadata, tags, locations, and file properties

The Inspector has two tabs:

  • Metadata — Edit fields like Artist, Album, Genre, Grouping, and Comment. Click “Write Metadata to File” to save changes directly to the audio file.
  • UCS — View and modify Universal Category System fields (CatID, Category, SubCategory, FXName, etc.)

Below the metadata, you’ll find:

  • Tags — View, add, or remove custom tags
  • Locations — See which folders and collections contain this file
  • Properties — Technical details including Duration, Sample Rate, Channels, Bitrate, Bit Depth, BPM, Format, File Size and Date Added.
