 # Libnyquist
 Libnyquist is a small C++11 library for reading sampled audio data from disk or memory. It's ideal to use as an audio asset frontend for games, audio sequencers, music players, and more.
 
-*The library is under active development and the API should be considered unstable. Check the Github issues queue for the state of the alpha.*
-
 The library steers away from patent-encumbered formats and those with non-BSD licensed codec implementations (such as MP3 and AAC, respectively). 
 
 Libnyquist is meant to be statically linked, which is not the case with other popular libraries like libsndfile (LGPL). Furthermore, the library is not concerned with legacy format support (for instance, A-law PCM encoding or SND files). 
  
-While untested, there are no technical conditions that preclude compilation on other platforms with C++11 support (Android 4.4+, Linux, iOS, etc).

-## Platform Support
+## Supported Project Files
-* Windows & Visual Studio 2013+
+* Visual Studio 2013
-* OSX & XCode 5+
+* XCode 6
 
 ## Known Issues
 * Ogg and Opus have conflicting mdct files. Their sources were modified such that they compile cleanly together in the same project.
 * Streaming is not supported for any file formats.
 
 ## Encoding
-WIP for 1.0-beta
+Simple but robust WAV format encoder now included. Extentions in the near future might include Ogg. 
 
 ## License
 Libyquist is released under the 2-Clause BSD license. All dependencies and codecs are under similar open licenses.
