Tau's True Audio (TTA) codec rewrite
TTA is a lossless audio codec designed around realtime hardware coding.

I recommend compiling with clang.
This project started as a fork of ttaenc 3.4.1 linux version (2007). Any code from ttaenc was put into the library, and the cli program was completely rewritten.
The library is just a collection of functions for reading from one buffer and writing to another with some support functions to calculate values. It does not allocate, print, nor make any other syscall. It does not even need libc as long as your compiler has a builtin memset and memmove (ie, not gcc). So fairly bare-bones as far as codec libraries go.
The two codec functions are reentrant, so you can code as few samples at a time with buffers as small as you want. ttaR (cli util) 1.0 did this, but I replaced it with doing the whole frame at once in 1.1 because it's a little faster and it simplified the source a bit.
