Generate retro sound effects and music in the browser with the Web Audio
API, so no audio files are needed. Any sound can still be replaced by a
file.
Audio (src/audio/):
- 16 effects (move, rotate, hold, hard drop, lock, line clears, garbage,
items, countdown, knockout, win/lose), triggered by comparing match
snapshots, so the server is unchanged
- Background music as a shuffled playlist of any number of tracks,
either synth songs or audio files; 3 original songs included, tempo
rises with the level
- SoundPlayer interface, so the audio engine can be replaced
- Audio files and music tracks are registered in theme/assets.ts
(soundFiles, musicTracks)
- All volume levels for developers are in config/sound.ts (master, sfx,
music, per effect, per track, default slider positions)
UI:
- Speaker button fixed in the top right corner of every screen; opens an
inline strip with a mute button and volume slider for SFX and music
that doesn't cover the boards or pause the game
- Leave button below it in the lobby and the game; in a running match
it asks for a second click because leaving gives up the match
- Lobby Music panel to switch single tracks on or off
- Keys: M all sound on/off, B music on/off, N next track
- Settings are saved in localStorage
Docs: audio section in frontend.md, sound and music guide in
extending.md, new keys in game-rules.md and the README.
