The Cue/EOM sub-tab is where you define how songs transition into one another. Two markers control the handoff between tracks:
Set these well and your segues will sound like they were planned by a human. Set them poorly and, well — that's what this tab is for.
The main display is a black waveform canvas showing two tracks at once:
Three markers float over the waveforms:
Song A loads automatically when you select a song in the middle pane. The waveform renders and playback starts near the end of the song (how near depends on the Playback Offset in Preferences — the default is 8 seconds from the end).
To load Song B — the "test-with" track — click Load test-with song and choose a song from your library. Pick something representative of what typically follows this type of song. You don't have to use the exact next song in any particular log; you just want to hear how the transition sounds in context.
It helps to have a small set of "test-with" songs that represent different types of intros — a cold start, a fade-in, a song that starts with a beat, one that starts with vocals. Using the same few test-with songs consistently makes your EOM settings more uniform across the library.
Press Space to start playback. Listen to the transition. When you hear the right moment to mark, press the key:
The markers appear on the waveform immediately. You can drop them while audio is playing — no need to pause first. If you miss the moment, keep playing and press the key again; the marker moves to the new position.
Press Space again to pause. Press Escape to clear both markers and reset the playhead to the default start position if you want to start over.
The zoom slider below the waveform canvas lets you zoom in for more precise marker placement. At full zoom, a small movement of the playhead represents a fraction of a second — useful when you need to place an EOM marker right at the moment a guitar chord fades out, rather than somewhere in the general neighborhood of it.
You can drag the markers directly on the waveform as well — click and drag the yellow or green marker line to fine-tune its position after placing it by ear.
Markers are saved to your library automatically when you move to a different song. There's no Save button to click — Librarian writes the EOM and Cue values to library.tsv as soon as you select a new track. The status bar confirms the save with a green flash on the speaker icon.
If a file can't be loaded — because it's missing from disk or the audio data is damaged — the waveform area stays blank, the song label turns red, and the speaker icon flashes red with an explanatory message in the status bar. The file needs to be located or repaired before you can set transition points for it.
EOM and Cue values are stored in seconds in the library. A song where the music ends at 3 minutes and 15 seconds gets an EOM value of 195. You can also type values directly into the EOM and Cue fields in the Edit Attributes sub-tab if you know the exact times.
