+
+/* Overview:
+
+   There is a large number of synthesis packages in use or development
+   on the Linux platform at this time. This API (`The Linux Audio
+   Developer's Simple Plugin API') attempts to give programmers the
+   ability to write simple `plugin' audio processors in C/C++ and link
+   them dynamically (`plug') into a range of these packages (`hosts').
+   It should be possible for any host and any plugin to communicate
+   completely through this interface.
+
+   This API is deliberately short and simple. To achieve compatibility
+   with a range of promising Linux sound synthesis packages it
+   attempts to find the `greatest common divisor' in their logical
+   behaviour. Having said this, certain limiting decisions are
+   implicit, notably the use of a fixed type (LADSPA_Data) for all
+   data transfer and absence of a parameterised `initialisation'
+   phase. See below for the LADSPA_Data typedef.
+
+   Plugins are expected to distinguish between control and audio
+   data. Plugins have `ports' that are inputs or outputs for audio or
+   control data and each plugin is `run' for a `block' corresponding
+   to a short time interval measured in samples. Audio data is
+   communicated using arrays of LADSPA_Data, allowing a block of audio
+   to be processed by the plugin in a single pass. Control data is
+   communicated using single LADSPA_Data values. Control data has a
+   single value at the start of a call to the `run()' or `run_adding()'
+   function, and may be considered to remain this value for its
+   duration. The plugin may assume that all its input and output ports
+   have been connected to the relevant data location (see the
+   `connect_port()' function below) before it is asked to run.
+
+   Plugins will reside in shared object files suitable for dynamic
+   linking by dlopen() and family. The file will provide a number of
+   `plugin types' that can be used to instantiate actual plugins
+   (sometimes known as `plugin instances') that can be connected
+   together to perform tasks.
+
+   This API contains very limited error-handling. */
+
+/*****************************************************************************/
+
+/* Fundamental data type passed in and out of plugin. This data type
+   is used to communicate audio samples and control values. It is
+   assumed that the plugin will work sensibly given any numeric input
+   value although it may have a preferred range (see hints below).
+
+   For audio it is generally assumed that 1.0f is the `0dB' reference
+   amplitude and is a `normal' signal level. */

+ * Because JACK has a very unflexible event loop management which
+ * doesn't allow us to add our own event sources to the event thread
+ * we cannot use the JACK real-time thread for dispatching our PA
+ * work. Instead, we run an additional RT thread which does most of
+ * the PA handling, and have the JACK RT thread request data from it
+ * via pa_asyncmsgq. The cost is an additional context switch which
+ * should hopefully not be that expensive if RT scheduling is
+ * enabled. A better fix would only be possible with additional event
+ * source support in JACK.

  * This document describes the client API for the PulseAudio sound

- * 
+ *
  * \li The complete but somewhat complicated to use asynchronous API
  * \li The simplified, easy to use, but limited synchronous API

- * linear2ulaw() accepts a 14-bit signed integer and encodes it as u-law data

- * stored in a unsigned char.  This function should only be called with

- * the data shifted such that it only contains information in the lower

- * 14-bits.

- *

- * In order to simplify the encoding process, the original linear magnitude

- * is biased by adding 33 which shifts the encoding range from (0 - 8158) to

- * (33 - 8191). The result can be seen in the following encoding table:

- *

- *	Biased Linear Input Code	Compressed Code

- *	------------------------	---------------

- *	00000001wxyza			000wxyz

- *	0000001wxyzab			001wxyz

- *	000001wxyzabc			010wxyz

- *	00001wxyzabcd			011wxyz

- *	0001wxyzabcde			100wxyz

- *	001wxyzabcdef			101wxyz

- *	01wxyzabcdefg			110wxyz

- *	1wxyzabcdefgh			111wxyz

- *

- * Each biased linear code has a leading 1 which identifies the segment

- * number. The value of the segment number is equal to 7 minus the number

- * of leading 0's. The quantization interval is directly available as the

- * four bits wxyz.  * The trailing bits (a - h) are ignored.

- *

- * Ordinarily the complement of the resulting code word is used for

- * transmission, and so the code word is complemented before it is returned.

+             *       If not connected, avg all S:*
+             *
+             * 6) Make sure S:Left/S:Right is used: S:Left/S:Right: If

+             *    channels. Gain is 0.1, the current left and right
+             *    should be multiplied by 0.9.
+             *
+             * 7) Make sure S:Center, S:LFE is used:
+             *
+             *    S:Center, S:LFE: If not connected, mix into all

+             *

+   The design goals of this code are:
+      - Very fast algorithm
+      - SIMD-friendly algorithm
+      - Low memory requirement
+      - Good *perceptual* quality (and not best SNR)
+
+   Warning: This resampler is relatively new. Although I think I got rid of
+   all the major bugs and I don't expect the API to change anymore, there
+   may be something I've missed. So use with caution.
+
+   This algorithm is based on this original resampling algorithm:
+   Smith, Julius O. Digital Audio Resampling Home Page
+   Center for Computer Research in Music and Acoustics (CCRMA),
+   Stanford University, 2007.
+   Web published at http://www-ccrma.stanford.edu/~jos/resample/.
+
+   There is one main difference, though. This resampler uses cubic
+   interpolation instead of linear interpolation in the above paper. This
+   makes the table much smaller and makes it possible to compute that table
+   on a per-stream basis. In turn, being able to tweak the table for each
+   stream makes it possible to both reduce complexity on simple ratios
+   (e.g. 2/3), and get rid of the rounding operations in the inner loop.
+   The latter both reduces CPU time and makes the algorithm more SIMD-friendly.

+ * Implementation of a time smoothing algorithm to synchronize remote
+ * clocks to a local one. Evens out noise, adjusts to clock skew and
+ * allows cheap estimations of the remote time while clock updates may
+ * be seldom and recieved in non-equidistant intervals.
+ *
+ * Basically, we estimate the gradient of received clock samples in a
+ * certain history window (of size 'history_time') with linear
+ * regression. With that info we estimate the remote time in
+ * 'adjust_time' ahead and smoothen our current estimation function
+ * towards that point with a 3rd order polynomial interpolation with
+ * fitting derivatives. (more or less a b-spline)
+ *
+ * The larger 'history_time' is chosen the better we will surpress
+ * noise -- but we'll adjust to clock skew slower..
+ *
+ * The larger 'adjust_time' is chosen the smoother our estimation
+ * function will be -- but we'll adjust to clock skew slower, too.
+ *
+ * If 'monotonic' is TRUE the resulting estimation function is
+ * guaranteed to be monotonic.
