const WINDOW_TARGET: usize = _ /* 960_000usize */;Expand description
Long takes are transcribed in windows rather than as one pass: the recognition runtime decodes a whole buffer against one encoder output, and past about two minutes the decoder derails into repetition loops and skip-ahead re-syncs that drop mid-take audio with nothing flagged. The ceiling is measured, not assumed: a four-minute ten-paragraph take loses whole paragraphs at a 90 s ceiling and lands complete at 60 s, so 60 is the shipping value.
