Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

win31-audio-design scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Win31 Audio Design: Satisfying Retro Sound Vocabulary

Expert in creating authentic Windows 3.1 era sound experiences for modern web and mobile applications. Focuses on CC-licensed alternatives to the classic sound vocabulary while capturing the satisfying, lo-fi essence of early 90s computing.

When to Use

Use for:

  • Win31-themed web applications needing audio feedback
  • Retro game interfaces with 90s desktop sounds
  • Mobile apps wanting satisfying micro-interaction sounds
  • Converting modern flat sounds to vintage 8-bit aesthetic
  • Creating sound palettes that evoke early Windows nostalgia

Do NOT use for:

  • Modern flat/material sound design → sound-engineer
  • Voice synthesis → voice-audio-engineer
  • Music composition → DAW tools
  • Film sound design → Linear audio workflows

Windows 3.1 Sound Vocabulary

The Original Sounds (Copyrighted - DO NOT USE)

File Character Duration Function
CHIMES.WAV Ethereal bells ~1.5s System notifications
CHORD.WAV Major chord resolve ~1.2s Task completion
DING.WAV Single bell strike ~0.5s Attention/alert
TADA.WAV Triumphant fanfare ~2s Startup/major success
RINGIN.WAV Rising tone ~0.3s Modal open
RINGOUT.WAV Falling tone ~0.2s Modal close

Legal Warning: These sounds are copyrighted by Microsoft. We create INSPIRED alternatives, never copies.

Sound Characteristics (What Made Them Satisfying)

Quality Win31 Sound Profile
Sample Rate 11kHz-22kHz (lo-fi charm)
Bit Depth 8-bit (quantization warmth)
Frequency Range 400Hz-4kHz (no sub-bass, gentle highs)
Envelope Fast attack, medium decay, no sustain
Reverb Dry or short room (no cathedral halls)
Character Bright, plasticky, cheerful

The Win31 "Ding" Formula

┌─────────────────────────────────────────────────────┐
│ Attack: 5-10ms    │ Pure sine starts BRIGHT         │
│ Peak: ~880Hz (A5) │ Classic 8-bit "bleep"           │
│ Decay: 200-400ms  │ Natural damping feel            │
│ Overtones: 2nd+3rd│ Bell-like shimmer               │
