This is a study to see how well the Opus audio codec works on a iPhone.

The opus code itself has purposely been left out. It can be downloaded from http://www.opus-codec.org/downloads/

Last tested on XCode 5.0.2 on OSX Mavericks using Opus 1.1.

Build Instructions

1. Download and extract the Opus source code using rake setup
2. Build the OpusIPhoneTest project using XCode

The Opus library .xcodeproj was originally created using gyp and the opus.gyp file extracted from the WebRTC open source project (https://code.google.com/p/webrtc/). It has subsequently been updated to support Opus 1.1 and the original opus.gyp removed so that I don't wonder why it doesn't work in the future.
