Meeting transcription stops at 30m - known limitation?

[keck]

As per title, I've tried recording/transcribing a few meetings to play with Logue, and all the transcriptions seem to stop right at 30 minutes - is this a known limit, configurable, or a function of my system memory somehow (it doesn't seem to be using very much at all, and wouldn't expect it does for a small model, but realize it may be a limitation of the context window)

Thanks for reporting this — it was a real bug, and a bad one. Not your memory and not the context window. Fix is up in #48.

What was happening

When a recording stops, Logue re-transcribes it with a more accurate batch model and swaps that in for the live transcript. The audio it kept for that pass was capped at 30 minutes — but the swap replaced the whole session regardless of how much the batch pass had actually heard.

So the live transcriber had your entire meeting, and the replacement threw away everything past the 30-minute mark, at the moment you hit stop. That's why it looked like a clean cut at exactly 30:00, and why memory usage looked low — the cap was holding the buffer at about 115 MB.

What changes

• The batch result can only replace the stretch of timeline it actually heard. Nothing gets deleted for being past a limit.
• Past what memory can hold, the recording is now read back from its own file a chunk at a time and processed to the end, so there is no longer a length at which the transcript or the speaker labels stop.
• If you'd turned your mic on during an online meeting, the limit was effectively halved and the timestamps drifted as the meeting went on — both capture streams were being appended to one buffer in arrival order rather than by time. That's fixed too.

Where that leaves things

Live transcript while recording	no limit
Final saved transcript	no limit
Batch-quality transcript + speaker labels	no limit — beyond roughly 2.3 h on 8 GB or 4.7 h on 16 GB+ it switches to reading from disk

Verified end to end against a five-hour two-speaker recording, plus a six-hour read-back test that holds under 4 MB resident.

One thing worth saying plainly: the meetings you already recorded lost that text when you stopped, and this fix can't bring it back — the audio is still on disk, but the transcript past 30 minutes is gone. Sorry about that. Anything you record after this ships keeps all of it.

Wow, glad I posted then - I couldn't find anything in apple's docs for the underlying interface limiting it to 30 minutes, so that makes sense, and yet was much more complicated than I thought it would be! Thanks for the quick fix!
