Bug Fixes
LaTeX - bugs
Fix #46 — Whisper Scribe crash on large audio files (both branches)
Audio decode used boxed List (~16 bytes/sample). A 30-minute recording at 16 kHz allocated ~460 MB before the
model even started. Replaced with a primitive FloatArray growing buffer (~4 bytes/sample, 4× reduction) — large
files now process without OOM.
Fix #47 — TTS silent on GrapheneOS when a non-Amy voice is downloaded (custom-rom-support only)
TTS auto-init always attempted to load the first model in the list (Amy) regardless of what was actually downloaded.
On GrapheneOS, with no Android TTS fallback, a failed Amy init produced silence with no error. Auto-init now
filters by ModelDownloadStatusType.SUCCEEDED before selecting a model to load.
