JZSpeexKit

An SpeexKit which can encode wav(caf) file to spx(using ogg container) and decode spx to wav(caf). Based on speex offical demo: speexenc.c and speexdec.c.

Add JZSpeexKit as a target dependency. Here are some great step-by-step instructions on how to add static library dependencies in more recent versions of Xcode. And do not forget setting HEADER SEARCHING PATH in TARGET BUILD SETTINGS.
