## What it is
DOUAudioStreamer is a Core Audio based streaming audio player library for iOS and macOS written in Objective-C. It plays remote URLs, local files, and media library items via a small DOUAudioFile protocol, exposing playback status, buffering progress, and download speed through KVO.

## Use cases
- stream music from a remote URL in an iOS app
- play local audio files on macOS
- show buffering progress and download speed during audio playback
- build a podcast or music player with play/pause/stop controls
- visualize audio playback with analyzers
- integrate audio streaming into an Objective-C app via CocoaPods

## When to choose
- you need a lightweight native Objective-C audio streaming player for iOS or macOS
- you want KVO-observable playback state like buffering ratio and download speed
- you need to support remote URLs, local files, and media library items with one protocol

## When to avoid
- you are building for Android, Windows, or the web
- you prefer a Swift-native or cross-platform audio framework
- you need advanced features like playlists, gapless playback, or DRM out of the box
