+////////////////////////////////////////////////////////////////////////////////

+///

+/// Win32 version of the AMD 3DNow! optimized routines for AMD K6-2/Athlon 

+/// processors. All 3DNow! optimized functions have been gathered into this

+/// single source code file, regardless to their class or original source code 

+/// file, in order to ease porting the library to other compiler and processor 

+/// platforms.

+///

+/// By the way; the performance gain depends heavily on the CPU generation: On 

+/// K6-2 these routines provided speed-up of even 2.4 times, while on Athlon the 

+/// difference to the original routines stayed at unremarkable 8%! Such a small 

+/// improvement on Athlon is due to 3DNow can perform only two operations in 

+/// parallel, and obviously also the Athlon FPU is doing a very good job with

+/// the standard C floating point routines! Here these routines are anyway, 

+/// although it might not be worth the effort to convert these to GCC platform, 

+/// for Athlon CPU at least. The situation is different regarding the SSE 

+/// optimizations though, thanks to the four parallel operations of SSE that 

+/// already make a difference.

+/// 

+/// This file is to be compiled in Windows platform with Microsoft Visual C++ 

+/// Compiler. Please see '3dnow_gcc.cpp' for the gcc compiler version for all

+/// GNU platforms (if file supplied).

+///

+/// NOTICE: If using Visual Studio 6.0, you'll need to install the "Visual C++ 

+/// 6.0 processor pack" update to support 3DNow! instruction set. The update is 

+/// available for download at Microsoft Developers Network, see here:

+/// http://msdn.microsoft.com/en-us/vstudio/aa718349.aspx

+///

+/// If the above URL is expired or removed, go to "http://msdn.microsoft.com" and 

+/// perform a search with keywords "processor pack".

+/// Beats-per-minute (BPM) detection routine.

+///

+/// The beat detection algorithm works as follows:

+/// - Use function 'inputSamples' to input a chunks of samples to the class for

+///   analysis. It's a good idea to enter a large sound file or stream in smallish

+///   chunks of around few kilosamples in order not to extinguish too much RAM memory.

+/// - Inputted sound data is decimated to approx 500 Hz to reduce calculation burden,

+///   which is basically ok as low (bass) frequencies mostly determine the beat rate.

+///   Simple averaging is used for anti-alias filtering because the resulting signal

+///   quality isn't of that high importance.

+/// - Decimated sound data is enveloped, i.e. the amplitude shape is detected by

+///   taking absolute value that's smoothed by sliding average. Signal levels that

+///   are below a couple of times the general RMS amplitude level are cut away to

+///   leave only notable peaks there.

+/// - Repeating sound patterns (e.g. beats) are detected by calculating short-term 

+///   autocorrelation function of the enveloped signal.

+/// - After whole sound data file has been analyzed as above, the bpm level is 

+///   detected by function 'getBpm' that finds the highest peak of the autocorrelation 

+///   function, calculates it's precise location and converts this reading to bpm's.

+///

+/// SoundTouch - main class for tempo/pitch/rate adjusting routines. 

+///

+/// Notes:

+/// - Initialize the SoundTouch object instance by setting up the sound stream 

+///   parameters with functions 'setSampleRate' and 'setChannels', then set 

+///   desired tempo/pitch/rate settings with the corresponding functions.

+///

+/// - The SoundTouch class behaves like a first-in-first-out pipeline: The 

+///   samples that are to be processed are fed into one of the pipe by calling

+///   function 'putSamples', while the ready processed samples can be read 

+///   from the other end of the pipeline with function 'receiveSamples'.

+/// 

+/// - The SoundTouch processing classes require certain sized 'batches' of 

+///   samples in order to process the sound. For this reason the classes buffer 

+///   incoming samples until there are enough of samples available for 

+///   processing, then they carry out the processing step and consequently

+///   make the processed samples available for outputting.

+/// 

+/// - For the above reason, the processing routines introduce a certain 

+///   'latency' between the input and output, so that the samples input to

+///   SoundTouch may not be immediately available in the output, and neither 

+///   the amount of outputtable samples may not immediately be in direct 

+///   relationship with the amount of previously input samples.

+///

+/// - The tempo/pitch/rate control parameters can be altered during processing.

+///   Please notice though that they aren't currently protected by semaphores,

+///   so in multi-thread application external semaphore protection may be

+///   required.

+///

+/// - This class utilizes classes 'TDStretch' for tempo change (without modifying

+///   pitch) and 'RateTransposer' for changing the playback rate (that is, both 

+///   tempo and pitch in the same ratio) of the sound. The third available control 

+///   'pitch' (change pitch but maintain tempo) is produced by a combination of

+///   combining the two other controls.
