INTRODUCTION
============
tooLAME is an optimized Mpeg Audio 1/2 Layer 2 encoder. It is based heavily on
- the ISO dist10 code
- improvement to algorithms as part of the LAME project (www.sulaco.org/mp3)
- work by Mike Cheng and other contributors (see CONTRIBUTORS)
CONTRIBUTORS
============
Dist10 code writers
LAME specific contributions
fht routines from Ron Mayer <mayer at acuson.com>
fht tweaking by Mathew Hendry <math at vissci.com>
window_subband & filter_subband from LAME circa v3.30
(multiple LAME authors)
(before Takehiro's window/filter/mdct combination)
Oliver Lietz <lietz at nanocosmos.de>
Tables now included in the exe! (yay! :)
Patrick de Smet <pds at telin.rug.ac.be>
scale_factor calc speedup.

(verbosity patch '-t' switch for transcode plugin)
Sami Sallinen - sami.sallinen at g-cluster.com
(filter_subband loop unroll
psycho_i fix for "% 1408" calcs)
Mike Cheng <mikecheng at NOT planckenergy.com> (remove the NOT)
Most of the rest
