Create DJ intros in seconds.

The adaptive grid follows tempo changes instead of forcing every bar to the same duration. Listen and check the waveform. Add a manual timing cue where a correction is needed; drag it to refine alignment. Phrase cues mark musical distances from cue zero.

Add Grid places a manual cue at the playhead; double-clicking an empty cue-strip location also adds one. Drag a manual cue to adjust it, or double-click that manual cue to remove it. Clear All removes manual cues. Generated phrase cues and manual timing cues serve different purposes.

Snap On aligns supported edits to the musical grid. Snap Off lets you place, trim, and cut freely. It does not erase the detected grid or change the audio’s tempo. Hold Command for a temporary snap bypass while making an edit.

Use the edge handles to trim, the fade handles to smooth the entrance or exit, and the repeat arrows to extend a phrase forward or backward. Move a region from its title strip. Undo and Redo let you compare edits without rebuilding your arrangement from scratch.

Use timeline zoom and horizontal navigation to move between a precise waveform view and the larger arrangement. In General settings, choose Mouse pointer or Playhead as the zoom focus. Cue-strip editing and playhead seeking are separate gestures.

Place built phrases before or after the original song to create mix-in and mix-out sections. Use In and Out to choose the exported range, then preview the join. Export names reflect the intro and outro presets present in the arrangement.

Play and stop from the transport. Use track Mute and Solo to compare the original song with the Intro Layer. The stereo meters and monitor level help you audition the edit while the time and tempo readouts keep its position clear.

Choose WAV for uncompressed audio or MP3 for a smaller, 320 kbps file. Set the export In and Out boundaries to define the section you want. Built-in limiting and the final peak check run before the file is written.

Intro Lab reads the source title and artist when available, uses the filename as a fallback, and adds an edit label such as “4 Bars Intro.” Exported tags include the title, artist when present, an Intro Lab comment, and Intro Lab artwork. It does not promise to preserve every original tag or cover image; tag display varies between players.

Open Intro Lab → Settings → General. Choose a default phrase length of 4, 8, or 16 bars for new sessions. Choose whether timeline zoom follows the playhead or mouse pointer. Changing the phrase default does not alter the current edit.

Choose English, Spanish, or Brazilian Portuguese, or follow your Mac’s language. Save Changes applies the selection and remembers it on this Mac. The translated interface keeps the same editing workflow.

Open Settings → Keyboard Shortcuts. Click a listed shortcut, press your preferred combination, then Save Changes. Use Command, Control, or Option as instructed. Restore Defaults brings back the standard assignments. Only the commands listed in this panel are customizable here.

Save Project keeps the editable arrangement; Export creates the finished audio file. Collect and Save gathers project assets for a portable copy. Use the File menu for these commands. Saving a project and exporting a song are separate actions.
