John Ripley's Miscellaneous Cruft
$ git clone git://git.miscellaneouscruft.com/om-codec.git
A from-scratch reimplementation of the Ogg Vorbis audio codec. This is written with memory sandboxing, fixed point and other requirements for embedded devices in mind. However, a primary goal is to stick with a high level language (C++) while still maintaining low CPU and memory footprint (this is possible!)

NDK Wrappers
I am no longer maintaining this project, and have not been doing so for a very long time already. It is obsolete and all of its features are included in modern Android NDK releases. Please do not contact me asking for this.
