Major surgery to websocket_remote:

Browse Source 
- Renamed websocket_remote plugin to "server"
- Added IEncoder, IEncoderFactory interfaces to SDK. Updated
IEnvironment and related plumbing; plugins can now declare encoders and
other plugins can request instances through the SDK.
- Removed LAME encoding from websocket_server plugin, created new
stockencoders plugin that includes both LAME and Ogg Vorbis encoders.
- Moved to dynamic libraries for ogg, vorbis, libvorbis so it can be
shared between encoding and decoding plugins.
- Plumbing for new "format" URL param through HttpServer, Transcoder,
and TranscodingDataStream. Use new IEncoder functionality to deal with
on-the-fly re-encoding

happen with absurdly closely spaced roots (very sharp peaks in the
LPC f response) which in turn should be impossible in our use of
the code. If this *does* happen anyway, it's a bug in the floor

function: normalized modified discrete cosine transform
power of two length transform only [64 <= n ]
last mod: $Id: mdct.c 16227 2009-07-08 06:58:46Z xiphmont $
Original algorithm adapted long ago from _The use of multirate filter
banks for coding of high quality digital audio_, by T. Sporer,
K. Brandenburg and B. Edler, collection of the European Signal
Processing Conference (EUSIPCO), Amsterdam, June 1992, Vol.1, pp
211-214
The below code implements an algorithm that no longer looks much like
that presented in the paper, but the basic structure remains if you
dig deep enough to see it.
This module DOES NOT INCLUDE code to generate/apply the window
function. Everybody has their own weird favorite including me... I
happen to like the properties of y=sin(.5PI*sin^2(x)), but others may
vehemently disagree.
********************************************************************/
/* this can also be run as an integer transform by uncommenting a
define in mdct.h; the integerization is a first pass and although
it's likely stable for Vorbis, the dynamic range is constrained and
roundoff isn't done (so it's noisy). Consider it functional, but
only a starting point. There's no point on a machine with an FPU */
