## What it is
Oto is a low-level Go library for playing sound across many platforms, including Windows, macOS, Linux, mobile, WebAssembly, and even game consoles. It provides a single audio Context from which any number of Players read PCM bytes from io.Readers and play them.

## Use cases
- play sound effects in a Go game
- play an mp3 file from memory in Go
- stream audio from a file in a cross-platform Go app
- add audio output to a Go mobile app
- play audio in a WebAssembly Go application

## When to choose
- you need cross-platform audio playback in Go with minimal dependencies
- you want no-Cgo audio on desktop platforms
- you are building a game or multimedia app with Ebitengine or similar

## When to avoid
- you need high-level audio features like mixing, effects, or decoding many formats
- you need audio recording or capture, not just playback
- you are not using Go

## Facets
- artifact type: library
- maturity: active
- function: audio-processing
- domain: cross-platform
- platform: windows, wasm, go, cross-platform
- tags: sound-playback, audio-output, game-audio, no-cgo, audio, game-development, linux, macos, android, ios
