Audio and video
Sonic identity and video production rules.
Audio identity
Four defined cues. All are short, tonal, and mid-register — the audio equivalent of “slides into place, doesn’t bounce”.
| Cue | Sound | Length |
|---|---|---|
| Notification | Short tonal chime, mid-register | 200ms |
| Success | Ascending C→E, warm sine wave | — |
| Error | Single low A2 | 300ms |
| Podcast intro | Ambient pad, tension→warmth resolve | 3s |
Error is a single low note, not a buzz or a descending pair — it marks the event without scolding.
Video rules
- Demos run at real time. No fast-forward, no speed ramps. If a step is slow, that is information the viewer needs.
- Transitions are a cut or a 200ms fade. No swoops, wipes, or 3D moves.
- All video uses midnight surfaces.
- Subtitles are always available.
- Export at 1080p minimum, 4K when possible.
Do
Show the real thing at real speed. Caption everything.
Don't
Speed up a demo to hide latency, or use a transition that draws attention to itself.
