An aircheck is an MP3 extract of a portion of the day — a single show, a single hour, a single segment — pulled out of the rolling DayTracker recording for keeping, sharing, or review. DayTracker can produce airchecks two ways:
This page covers the scheduled variety, which is what the Airchecks tab is for.
All airchecks — scheduled or manual — go to a single folder, organized so they're easy to find later:
~/Station/Logs/Airchecks/
Filenames carry the label, the date, and the hour window so you can identify them at a glance:
Aircheck_<label>_<YYYY-MM-DD>_<HH-HH>.mp3
For scheduled airchecks, the filename also gets a _Live or _VT tag depending on the mode of the card.
The Airchecks tab is a vertical stack of cards. Each card defines one recurring aircheck. You can add as many as you need — one per show, one per shift, one per daypart.
Each card has these fields:
| Field | What it does |
|---|---|
| Name | Friendly label for the aircheck — shows up in the filename. For example, "Mike's Wednesday Show" or "Morning Drive." |
| Active | Checkbox at the top-right. When off, the card is saved but no airchecks are exported. Use this to pause a rule without deleting it. |
| Days | Seven checkboxes — M, T, W, T, F, S, S. Tick the days the aircheck should run. Mon-Fri for a weekday show, Sat-Sun for a weekend show, single days for one-off recurring captures. |
| Hours | Start hour and end hour, on the 24-hour clock. The aircheck covers everything from the top of the start hour to the top of the end+1 hour. For an 18:00-21:00 show, set Start to 18 and End to 20 — the export covers 18:00 through 21:00. |
| Mode | Live DJ or Voicetracks. This is a marker filter, not an audio filter — DayTracker exports the segments of the hour window that match the chosen mode. A "Live DJ" card captures the stretches where the live-mic was open; a "Voicetracks" card captures everything else. |
| Status line | "Has not run yet" or "Last exported: 2026-05-11," so you know when the card last produced a file. |
| + / − | Add a new card below this one, or remove this one. |
Every 30 seconds DayTracker checks each active card to see whether its window has just finished for the current day. When it has, DayTracker scans the markers for the matching mode within the window, stitches those segments into a single MP3, and writes it to the Airchecks folder. The status line on the card updates with the new "Last exported" date.
If DayTracker wasn't running when a window closed (a power outage, an unscheduled restart), that window is skipped — DayTracker doesn't back-fill missed runs. The next scheduled run still happens as expected.
Set up your most important shows first — the ones you want every episode of in case someone calls and asks for a copy. Live talk, special events, request shows. The ones where having the recording matters most.
The Live DJ / Voicetracks switch on a card tells DayTracker which marker spans to include in the export:
mic_start and mic_end markers in the window. The live mic is what matters; the music in between gets dropped. The resulting aircheck plays back as a sequence of mic-open moments, end to end.vt_start and vt_end markers. The pre-recorded voice cuts only; everything else gets dropped.Use Live DJ for live shows. Use Voicetracks for tracked shows. If you want the whole thing — music included — make a manual selection on the timeline that spans the show and export it with E instead.
If a scheduled aircheck runs and finds no matching markers in its window, the status bar reports "Scheduled aircheck \"name\": no segments in window." and no file is written. This usually means:
Adjust the card and the next scheduled run will produce the file you want.
