README
## StreamingKit
StreamingKit (formally Audjustable) is an audio playback and streaming library for iOS and Mac OSX. StreamingKit uses CoreAudio to decompress and playback audio (using hardware or software codecs) whilst providing a clean and simple object-oriented API.
The primary motivation of this project was to decouple the input data sources from the actual player logic in order to allow advanced customizable input handling such as HTTP progressive download based streaming, encryption/decryption, auto-recovery, dynamic-buffering. StreamingKit is the only streaming and playback library that supports dead-easy [gapless playback](https://github.com/tumtumtum/StreamingKit/wiki/Gapless-playback) between audio files of differing formats.
## Main Features
* Free OSS.
* Simple API.
* Easy to read source.
* Carefully multi-threaded to provide a responsive API that won't block your UI thread nor starve the audio buffers.
* Buffered and gapless playback between all format types.
* Easy to implement audio data sources (Local, HTTP, AutoRecoveringHTTP DataSources are provided).
* Easy to extend DataSource to support adaptive buffering, encryption, etc.
* Optimised for low CPU/battery usage (0% - 1% CPU usage when streaming).
* Optimised for linear data sources. Random access sources are required only for seeking.
* StreamingKit 0.2.0 uses the AudioUnit API rather than the slower AudioQueues API which allows real-time interception of the raw PCM data for features such as level metering, EQ, etc.
* Power metering
* Inbuilt equalizer/EQ (iOS 5.0 and above, OSX 10.9 Mavericks and above) with support for dynamically changing/enabling/disabling EQ while playing.
* Example apps for iOS and Mac OSX provided.
## Installation
StreamingKit is available as a [Cocoapod](http://cocoapods.org/?q=StreamingKit). You can also simply copy all the source files located inside StreamingKit/StreamingKit/* into your Xcode project.
## Example
There are two main classes. The `STKDataSource` class which is the abstract base class for the various compressed audio data sources. The `STKAudioPlayer` class manages and renders audio from a queue DataSources. By default `STKAudioPlayer` will automatically parse URLs and create the appropriate data source internally.
### Play an MP3 over HTTP
```objective-c
STKAudioPlayer* audioPlayer = [[STKAudioPlayer alloc] init];
[audioPlayer play:@"http://www.abstractpath.com/files/audiosamples/sample.mp3"];
```
### Gapless playback
```objective-c
STKAudioPlayer* audioPlayer = [[STKAudioPlayer alloc] init];
[audioPlayer queue:@"http://www.abstractpath.com/files/audiosamples/sample.mp3"];
[audioPlayer queue:@"http://www.abstractpath.com/files/audiosamples/airplane.aac"];
```
### Intercept PCM data just before its played
```objective-c
[audioPlayer appendFrameFilterWithName:@"MyCustomFilter" block:^(UInt32 channelsPerFrame, UInt32 bytesPerFrame, UInt32 frameCount, void* frames)
{
...
}];
