+ * The Rubber Band API is contained in the single class
+ * RubberBand::RubberBandStretcher.
+ * 
+ * Threading notes for real-time applications:
+ * 
+ * Multiple instances of RubberBandStretcher may be created and used
+ * in separate threads concurrently.  However, for any single instance
+ * of RubberBandStretcher, you may not call process() more than once
+ * concurrently, and you may not change the time or pitch ratio while
+ * a process() call is being executed (if the stretcher was created in
+ * "real-time mode"; in "offline mode" you can't change the ratios
+ * during use anyway).
+ * 
+ * So you can run process() in its own thread if you like, but if you
+ * want to change ratios dynamically from a different thread, you will
+ * need some form of mutex in your code.  Changing the time or pitch
+ * ratio is real-time safe except in extreme circumstances, so for
+ * most applications that may change these dynamically it probably
+ * makes most sense to do so from the same thread as calls process(),
+ * even if that is a real-time thread.

+     * Processing options for the timestretcher.  The preferred
+     * options should normally be set in the constructor, as a bitwise
+     * OR of the option flags.  The default value (DefaultOptions) is
+     * intended to give good results in most situations.
+     *
+     * 1. Flags prefixed \c OptionProcess determine how the timestretcher
+     * will be invoked.  These options may not be changed after
+     * construction.
+     * 
+     *   \li \c OptionProcessOffline - Run the stretcher in offline
+     *   mode.  In this mode the input data needs to be provided
+     *   twice, once to study(), which calculates a stretch profile
+     *   for the audio, and once to process(), which stretches it.
+     *
+     *   \li \c OptionProcessRealTime - Run the stretcher in real-time
+     *   mode.  In this mode only process() should be called, and the
+     *   stretcher adjusts dynamically in response to the input audio.
+     * 
+     * The Process setting is likely to depend on your architecture:
+     * non-real-time operation on seekable files: Offline; real-time
+     * or streaming operation: RealTime.
+     *
+     * 2. Flags prefixed \c OptionStretch control the profile used for
+     * variable timestretching.  Rubber Band always adjusts the
+     * stretch profile to minimise stretching of busy broadband
+     * transient sounds, but the degree to which it does so is
+     * adjustable.  These options may not be changed after
+     * construction.
+     *
+     *   \li \c OptionStretchElastic - Only meaningful in offline
+     *   mode, and the default in that mode.  The audio will be
+     *   stretched at a variable rate, aimed at preserving the quality
+     *   of transient sounds as much as possible.  The timings of low
+     *   activity regions between transients may be less exact than
+     *   when the precise flag is set.
+     * 
+     *   \li \c OptionStretchPrecise - Although still using a variable
+     *   stretch rate, the audio will be stretched so as to maintain
+     *   as close as possible to a linear stretch ratio throughout.
+     *   Timing may be better than when using \c OptionStretchElastic, at
+     *   slight cost to the sound quality of transients.  This setting
+     *   is always used when running in real-time mode.
+     *
+     * 3. Flags prefixed \c OptionTransients control the component
+     * frequency phase-reset mechanism that may be used at transient
+     * points to provide clarity and realism to percussion and other
+     * significant transient sounds.  These options may be changed
+     * after construction when running in real-time mode, but not when
+     * running in offline mode.
+     * 
+     *   \li \c OptionTransientsCrisp - Reset component phases at the
+     *   peak of each transient (the start of a significant note or
+     *   percussive event).  This, the default setting, usually
+     *   results in a clear-sounding output; but it is not always
+     *   consistent, and may cause interruptions in stable sounds
+     *   present at the same time as transient events.  The
+     *   OptionDetector flags (below) can be used to tune this to some
+     *   extent.
+     *
+     *   \li \c OptionTransientsMixed - Reset component phases at the
+     *   peak of each transient, outside a frequency range typical of
+     *   musical fundamental frequencies.  The results may be more
+     *   regular for mixed stable and percussive notes than
+     *   \c OptionTransientsCrisp, but with a "phasier" sound.  The
+     *   balance may sound very good for certain types of music and
+     *   fairly bad for others.
+     *
+     *   \li \c OptionTransientsSmooth - Do not reset component phases
+     *   at any point.  The results will be smoother and more regular
+     *   but may be less clear than with either of the other
+     *   transients flags.
+     *
+     * 4. Flags prefixed \c OptionDetector control the type of
+     * transient detector used.  These options may be changed
+     * after construction when running in real-time mode, but not when
+     * running in offline mode.
+     *
+     *   \li \c OptionDetectorCompound - Use a general-purpose
+     *   transient detector which is likely to be good for most
+     *   situations.  This is the default.
+     *
+     *   \li \c OptionDetectorPercussive - Detect percussive
+     *   transients.  Note that this was the default and only option
+     *   in Rubber Band versions prior to 1.5.
+     *
+     *   \li \c OptionDetectorSoft - Use an onset detector with less
+     *   of a bias toward percussive transients.  This may give better
+     *   results with certain material (e.g. relatively monophonic
+     *   piano music).
+     *
+     * 5. Flags prefixed \c OptionPhase control the adjustment of
+     * component frequency phases from one analysis window to the next
+     * during non-transient segments.  These options may be changed at
+     * any time.
+     *
+     *   \li \c OptionPhaseLaminar - Adjust phases when stretching in
+     *   such a way as to try to retain the continuity of phase
+     *   relationships between adjacent frequency bins whose phases
+     *   are behaving in similar ways.  This, the default setting,
+     *   should give good results in most situations.
+     *
+     *   \li \c OptionPhaseIndependent - Adjust the phase in each
+     *   frequency bin independently from its neighbours.  This
+     *   usually results in a slightly softer, phasier sound.
+     *
+     * 6. Flags prefixed \c OptionThreading control the threading
+     * model of the stretcher.  These options may not be changed after
+     * construction.
+     *
+     *   \li \c OptionThreadingAuto - Permit the stretcher to
+     *   determine its own threading model.  Usually this means using
+     *   one processing thread per audio channel in offline mode if
+     *   the stretcher is able to determine that more than one CPU is
+     *   available, and one thread only in realtime mode.  This is the
+     *   defafult.
+     *
+     *   \li \c OptionThreadingNever - Never use more than one thread.
+     *  
+     *   \li \c OptionThreadingAlways - Use multiple threads in any
+     *   situation where \c OptionThreadingAuto would do so, except omit
+     *   the check for multiple CPUs and instead assume it to be true.
+     *
+     * 7. Flags prefixed \c OptionWindow control the window size for
+     * FFT processing.  The window size actually used will depend on
+     * many factors, but it can be influenced.  These options may not
+     * be changed after construction.
+     *
+     *   \li \c OptionWindowStandard - Use the default window size.
+     *   The actual size will vary depending on other parameters.
+     *   This option is expected to produce better results than the
+     *   other window options in most situations.
+     *
+     *   \li \c OptionWindowShort - Use a shorter window.  This may
+     *   result in crisper sound for audio that depends strongly on
+     *   its timing qualities.
+     *
+     *   \li \c OptionWindowLong - Use a longer window.  This is
+     *   likely to result in a smoother sound at the expense of
+     *   clarity and timing.
+     *
+     * 8. Flags prefixed \c OptionSmoothing control the use of
+     * window-presum FFT and time-domain smoothing.  These options may
+     * not be changed after construction.
+     *
+     *   \li \c OptionSmoothingOff - Do not use time-domain smoothing.
+     *   This is the default.
+     *
+     *   \li \c OptionSmoothingOn - Use time-domain smoothing.  This
+     *   will result in a softer sound with some audible artifacts
+     *   around sharp transients, but it may be appropriate for longer
+     *   stretches of some instruments and can mix well with
+     *   OptionWindowShort.
+     *
+     * 9. Flags prefixed \c OptionFormant control the handling of
+     * formant shape (spectral envelope) when pitch-shifting.  These
+     * options may be changed at any time.
+     *
+     *   \li \c OptionFormantShifted - Apply no special formant
+     *   processing.  The spectral envelope will be pitch shifted as
+     *   normal.  This is the default.
+     *
+     *   \li \c OptionFormantPreserved - Preserve the spectral
+     *   envelope of the unshifted signal.  This permits shifting the
+     *   note frequency without so substantially affecting the
+     *   perceived pitch profile of the voice or instrument.
+     *
+     * 10. Flags prefixed \c OptionPitch control the method used for
+     * pitch shifting.  These options may be changed at any time.
+     * They are only effective in realtime mode; in offline mode, the
+     * pitch-shift method is fixed.
+     *
+     *   \li \c OptionPitchHighSpeed - Use a method with a CPU cost
+     *   that is relatively moderate and predictable.  This may
+     *   sound less clear than OptionPitchHighQuality, especially
+     *   for large pitch shifts.  This is the default.
+
+     *   \li \c OptionPitchHighQuality - Use the highest quality
+     *   method for pitch shifting.  This method has a CPU cost
+     *   approximately proportional to the required frequency shift.
+
+     *   \li \c OptionPitchHighConsistency - Use the method that gives
+     *   greatest consistency when used to create small variations in
+     *   pitch around the 1.0-ratio level.  Unlike the previous two
+     *   options, this avoids discontinuities when moving across the
+     *   1.0 pitch scale in real-time; it also consumes more CPU than
+     *   the others in the case where the pitch scale is exactly 1.0.
+     *
+     * 11. Flags prefixed \c OptionChannels control the method used for
+     * processing two-channel audio.  These options may not be changed
+     * after construction.
+     *
+     *   \li \c OptionChannelsApart - Each channel is processed
+     *   individually, though timing is synchronised and phases are
+     *   synchronised at transients (depending on the OptionTransients
+     *   setting).  This gives the highest quality for the individual
+     *   channels but a relative lack of stereo focus and unrealistic
+     *   increase in "width".  This is the default.
+     *
+     *   \li \c OptionChannelsTogether - The first two channels (where
+     *   two or more are present) are considered to be a stereo pair
+     *   and are processed in mid-side format; mid and side are
+     *   processed individually, with timing synchronised and phases
+     *   synchronised at transients (depending on the OptionTransients
+     *   setting).  This usually leads to better focus in the centre
+     *   but a loss of stereo space and width.  Any channels beyond
+     *   the first two are processed individually.
