     - In parts. Write a 70 min MP3 of two voices, a 300 Hz tone and a 700 Hz tone that take turns every 45 s: `ffmpeg -f lavfi -i "aevalsrc='0.5*sin(2*PI*if(lt(mod(t\,90)\,45)\,300\,700)*t)':s=8000:d=4200" -ac 1 -ar 8000 -b:a 8k "$VAULT/Fixtures/Two Voices.mp3"`.

The fixture numbers the voices in the order they sound in each request, so the second part, which starts with the high tone, numbers them the other way. The note still numbers the low voice `1` and the high voice `2` throughout, the paragraph at `00:23:15` runs on across the first part boundary, and the progress notice ends with `Transcription completed and saved.` With `ElevenLabs Scribe v2` the parts go as multipart, no reel follows, each part's fixed answer numbers two more speakers, and the notice ends with `OpenRouter transcribed this episode in 3 parts, and speaker labels restart in each, so one person can have several labels.`

-    - Speaker labels. With `Speaker labels` on, as in a library that labelled speakers with OpenAI on 2.24.0, the progress notice ends with `Saved without speaker labels, because OpenAI does not label speakers. These providers do: ElevenLabs, Deepgram, OpenRouter.` and stays until clicked.

 - **Proof.** Screenshot the opened note (`npm run capture:e2e-obsidian -- screenshot .obsidian-e2e-artifacts/transcripts/note.png`), keep the note text, `$NET log` and `fixtures.mjs requests` for every run, and read `data.json` to show no new field.
