+///
+/// 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

+/// 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.
