SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

Simple soundboard app with hotkeys
A soundboard that supports almost all MP3s and WAVs. Sounds can be triggered with custom keyboard hot-keys and played through up to 2 outputs. i.e. Your speakers and a virtual audio cable. Also allows for your mic to pass into the virtual audio cable when enabling Mic Injector. This soundboard also incorporates a save feature. REQUIREMENTS: - Java 7 If you want sounds to be played through voice chat you'll need a virtual audio cable. (For Windows users I recommend the VB-Cable driver (http://vb-audio.pagesperso-orange.fr/Cable/index.htm). (For Mac I recommend Soundflower. (http://cycling74.com/soundflower-landing-page/)).
