recent changes

Here is an overview of some of the changes since the release of version 0.06. It's a more detailed list than what's in the Changelog, but it's simpler than having to go through the 90 SVN commit messages.

• fixed piped input for Windows
• several updates to the public API, including splitting the public header
• Prakash added C++ bindings
• utility functions for acmod and lfe were fixed, cleaned-up, and simplified
• fixed dual-mono encoding
• added a completely new bit allocation search method, which was a collaboration between Prakash and myself. The advantage of the new method is that it gives the same results no matter what the search start value is.
• version info is now accessible in API and displayed on commandline
• parallel encoding by Prakash. this is the most significant change since the last release.
• fixed bit exactness/uninitialized memory problem in exponent encoding
• added option to remove start-of-frame padding
• split out the commandline help in aften to a separate files to make it simpler and easier to maintain
  
• a number of excellent speed-ups by Prakash in the exponent functions
• added optional fast exponent strategy option which uses a fixed strategy, which is not quite as good quality, but is significantly faster
• fixed alt bitstream syntax encoding
