## What it is
Kira is a backend-agnostic Rust library for creating expressive audio in games. It provides tweens for smoothly adjusting sound properties, a flexible mixer with effects, a clock system for precise timing, and spatial audio support.

## Use cases
- play sound effects in a game
- smoothly tween playback rate or volume of sounds
- apply filters and effects via a mixer
- sync sounds to a musical beat or tempo
- add spatial/positional audio to a game

## When to choose
- you're building a game in Rust and need expressive, flexible audio control
- you need precise timing of audio events relative to a clock or tempo
- you want effects, sub-tracks, and parameter tweens out of the box

## When to avoid
- you need a full game engine rather than an audio library
- you're not working in Rust or a Rust-compatible environment
- you only need simple one-shot audio playback with minimal API surface

## Facets
- artifact type: library
- maturity: active
- function: audio-processing
- domain: -
- platform: rust, cross-platform
- tags: game-audio, mixer, spatial-audio, tweens, sound-playback, game-development, audio
