# Sound effect credits

All clips come from **Mixkit** and are used under the **Mixkit Sound Effects Free License**. The license allows commercial and personal use and does not require attribution, but we credit Mixkit anyway. Terms: https://mixkit.co/license/

Each clip was downloaded from Mixkit's public preview file, then processed with ffmpeg: converted to mono, leading silence trimmed, cut to length, loudness-normalized, and encoded as 96 kbps MP3. The record scratch is mastered a few dB louder than the rest on purpose.

## Missing (the synthesized placeholder plays instead)

- **ooh** (crowd "oooh"): no clean, clearly licensed clip found on Mixkit or Wikimedia Commons.
- **airhorn**: the same. Mixkit only has clown and car horns.

Lane 2: if you find good versions, drop them in as `ooh.mp3` / `airhorn.mp3` (under ~200 KB) and add a row above.

## Alternates worth trying (Mixkit IDs, same license)

- stamp: 833 (Metal hammer hit), 2294 (Drum bass hit)
- scratch: 704 (Vinyl stop fast scratch), 703 (forward and back fast scratch)
- chime: 2015 (Winning chimes), 3109 (Relaxing bell chime)
- rimshot: 2893 (Bad joke drums), 578 (Joke drums)
- trombone: 744 (Trombone disappoint, shorter at 2 s)
- fanfare: 2293 (Trumpet fanfare), 631 (Grand brass fanfare)

To swap one in: download `https://assets.mixkit.co/active_storage/sfx/<ID>/<ID>-preview.mp3` and rename it to the cue name.
