+
+ @brief Buffer Processor prototypes. A Buffer Processor performs buffer length
+ adaption, coordinates sample format conversion, and interleaves/deinterleaves
+ channels.
+
+ Overview
+
+ The "Buffer Processor" (PaUtilBufferProcessor) manages conversion of audio
+ data from host buffers to user buffers and back again. Where required, the
+ buffer processor takes care of converting between host and user sample formats,
+ interleaving and deinterleaving multichannel buffers, and adapting between host
+ and user buffers with different lengths. The buffer processor may be used with
+ full and half duplex streams, for both callback streams and blocking read/write
+ streams.
+
+ One of the important capabilities provided by the buffer processor is
+ the ability to adapt between user and host buffer sizes of different lengths
+ with minimum latency. Although this task is relatively easy to perform when
+ the host buffer size is an integer multiple of the user buffer size, the
+ problem is more complicated when this is not the case - especially for
+ full-duplex callback streams. Where necessary the adaption is implemented by
+ internally buffering some input and/or output data. The buffer adation
+ algorithm used by the buffer processor was originally implemented by
+ Stephan Letz for the ASIO version of PortAudio, and is described in his
+ Callback_adaption_.pdf which is included in the distribution.
+
+ The buffer processor performs sample conversion using the functions provided
+ by pa_converters.c.
+
+ The following sections provide an overview of how to use the buffer processor.
+ Interested readers are advised to consult the host API implementations for
+ examples of buffer processor usage.
+
+
+ Initialization, resetting and termination
+
+ When a stream is opened, the buffer processor should be initialized using
+ PaUtil_InitializeBufferProcessor. This function initializes internal state
+ and allocates temporary buffers as neccesary according to the supplied
+ configuration parameters. Some of the parameters correspond to those requested
+ by the user in their call to Pa_OpenStream(), others reflect the requirements
+ of the host API implementation - they indicate host buffer sizes, formats,
+ and the type of buffering which the Host API uses. The buffer processor should
+ be initialized for callback streams and blocking read/write streams.
+
+ Call PaUtil_ResetBufferProcessor to clear any sample data which is present
+ in the buffer processor before starting to use it (for example when
+ Pa_StartStream is called).
+
+ When the buffer processor is no longer used call
+ PaUtil_TerminateBufferProcessor.
+
+
+ Using the buffer processor for a callback stream
+
+ The buffer processor's role in a callback stream is to take host input buffers
+ process them with the stream callback, and fill host output buffers. For a
+ full duplex stream, the buffer processor handles input and output simultaneously
+ due to the requirements of the minimum-latency buffer adation algorithm.
+
+ When a host buffer becomes available, the implementation should call
+ the buffer processor to process the buffer. The buffer processor calls the
+ stream callback to consume and/or produce audio data as necessary. The buffer
+ processor will convert sample formats, interleave/deinterleave channels,
+ and slice or chunk the data to the appropriate buffer lengths according to
+ the requirements of the stream callback and the host API.
+
+ To process a host buffer (or a pair of host buffers for a full-duplex stream)
+ use the following calling sequence:
+
+ -# Call PaUtil_BeginBufferProcessing
+ -# For a stream which takes input:
+ - Call PaUtil_SetInputFrameCount with the number of frames in the host input
+ buffer.
+ - Call one of the following functions one or more times to tell the
+ buffer processor about the host input buffer(s): PaUtil_SetInputChannel,
+ PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel.
+ Which function you call will depend on whether the host buffer(s) are
+ interleaved or not.
+ - If the available host data is split accross two buffers (for example a
+ data range at the end of a circular buffer and another range at the
+ beginning of the circular buffer), also call
+ PaUtil_Set2ndInputFrameCount, PaUtil_Set2ndInputChannel,
+ PaUtil_Set2ndInterleavedInputChannels,
+ PaUtil_Set2ndNonInterleavedInputChannel as necessary to tell the buffer
+ processor about the second buffer.
+ -# For a stream which generates output:
+ - Call PaUtil_SetOutputFrameCount with the number of frames in the host
+ output buffer.
+ - Call one of the following functions one or more times to tell the
+ buffer processor about the host output buffer(s): PaUtil_SetOutputChannel,
+ PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel.
+ Which function you call will depend on whether the host buffer(s) are
+ interleaved or not.
+ - If the available host output buffer space is split accross two buffers
+ (for example a data range at the end of a circular buffer and another
+ range at the beginning of the circular buffer), call
+ PaUtil_Set2ndOutputFrameCount, PaUtil_Set2ndOutputChannel,
+ PaUtil_Set2ndInterleavedOutputChannels,
+ PaUtil_Set2ndNonInterleavedOutputChannel as necessary to tell the buffer
+ processor about the second buffer.
+ -# Call PaUtil_EndBufferProcessing, this function performs the actual data
+ conversion and processing.
+
+
+ Using the buffer processor for a blocking read/write stream
+
+ Blocking read/write streams use the buffer processor to convert and copy user
+ output data to a host buffer, and to convert and copy host input data to
+ the user's buffer. The buffer processor does not perform any buffer adaption.
+ When using the buffer processor in a blocking read/write stream the input and
+ output conversion are performed separately by the PaUtil_CopyInput and
+ PaUtil_CopyOutput functions.
+
+ To copy data from a host input buffer to the buffer(s) which the user supplies
+ to Pa_ReadStream, use the following calling sequence.
+
+ - Repeat the following three steps until the user buffer(s) have been filled
+ with samples from the host input buffers:
+ -# Call PaUtil_SetInputFrameCount with the number of frames in the host
+ input buffer.
+ -# Call one of the following functions one or more times to tell the
+ buffer processor about the host input buffer(s): PaUtil_SetInputChannel,
+ PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel.
+ Which function you call will depend on whether the host buffer(s) are
+ interleaved or not.
+ -# Call PaUtil_CopyInput with the user buffer pointer (or a copy of the
+ array of buffer pointers for a non-interleaved stream) passed to
+ Pa_ReadStream, along with the number of frames in the user buffer(s).
+ Be careful to pass a copy of the user buffer pointers to
+ PaUtil_CopyInput because PaUtil_CopyInput advances the pointers to
+ the start of the next region to copy.
+ - PaUtil_CopyInput will not copy more data than is available in the
+ host buffer(s), so the above steps need to be repeated until the user
+ buffer(s) are full.
+
+
+ To copy data to the host output buffer from the user buffers(s) supplied
+ to Pa_WriteStream use the following calling sequence.
+
+ - Repeat the following three steps until all frames from the user buffer(s)
+ have been copied to the host API:
+ -# Call PaUtil_SetOutputFrameCount with the number of frames in the host
+ output buffer.
+ -# Call one of the following functions one or more times to tell the
+ buffer processor about the host output buffer(s): PaUtil_SetOutputChannel,
+ PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel.
+ Which function you call will depend on whether the host buffer(s) are
+ interleaved or not.
+ -# Call PaUtil_CopyOutput with the user buffer pointer (or a copy of the
+ array of buffer pointers for a non-interleaved stream) passed to
+ Pa_WriteStream, along with the number of frames in the user buffer(s).
+ Be careful to pass a copy of the user buffer pointers to
+ PaUtil_CopyOutput because PaUtil_CopyOutput advances the pointers to
+ the start of the next region to copy.
+ - PaUtil_CopyOutput will not copy more data than fits in the host buffer(s),
+ so the above steps need to be repeated until all user data is copied.

+ without requiring the use of any locks. This only works when there is
+ a single reader and a single writer (ie. one thread or callback writes
+ to the ring buffer, another thread or callback reads from it).
+
+ The PaUtilRingBuffer structure manages a ring buffer containing N
+ elements, where N must be a power of two. An element may be any size
+ (specified in bytes).
+
+ The memory area used to store the buffer elements must be allocated by
+ the client prior to calling PaUtil_InitializeRingBuffer() and must outlive
+ the use of the ring buffer.
+
+ @note The ring buffer functions are not normally exposed in the PortAudio libraries.
+ If you want to call them then you will need to add pa_ringbuffer.c to your application source code.

+ IMPORTANT:
+
+ WASAPI is implemented for Callback and Blocking interfaces. It supports Shared and Exclusive
+ share modes.
+
+ Exclusive Mode:
+
+ Exclusive mode allows to deliver audio data directly to hardware bypassing
+ software mixing.
+ Exclusive mode is specified by 'paWinWasapiExclusive' flag.
+
+ Callback Interface:
+
+ Provides best audio quality with low latency. Callback interface is implemented in
+ two versions:
+
+ 1) Event-Driven:
+ This is the most powerful WASAPI implementation which provides glitch-free
+ audio at around 3ms latency in Exclusive mode. Lowest possible latency for this mode is
+ 3 ms for HD Audio class audio chips. For the Shared mode latency can not be
+ lower than 20 ms.
+
+ 2) Poll-Driven:
+ Polling is another 2-nd method to operate with WASAPI. It is less efficient than Event-Driven
+ and provides latency at around 10-13ms. Polling must be used to overcome a system bug
+ under Windows Vista x64 when application is WOW64(32-bit) and Event-Driven method simply
+ times out (event handle is never signalled on buffer completion). Please note, such WOW64 bug
+ does not exist in Vista x86 or Windows 7.
+ Polling can be setup by speciying 'paWinWasapiPolling' flag. Our WASAPI implementation detects
+ WOW64 bug and sets 'paWinWasapiPolling' automatically.
+
+ Thread priority:
+
+ Normally thread priority is set automatically and does not require modification. Although
+ if user wants some tweaking thread priority can be modified by setting 'paWinWasapiThreadPriority'
+ flag and specifying 'PaWasapiStreamInfo::threadPriority' with value from PaWasapiThreadPriority
+ enum.
+
+ Blocking Interface:
+
+ Blocking interface is implemented but due to above described Poll-Driven method can not
+ deliver lowest possible latency. Specifying too low latency in Shared mode will result in
+ distorted audio although Exclusive mode adds stability.
+
+ Pa_IsFormatSupported:
+
+ To check format with correct Share Mode (Exclusive/Shared) you must supply
+ PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
+ PaStreamParameters::hostApiSpecificStreamInfo structure.
+
+ Pa_OpenStream:
+
+ To set desired Share Mode (Exclusive/Shared) you must supply
+ PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
+ PaStreamParameters::hostApiSpecificStreamInfo structure.

+ The callback function is responsible for processing buffers of audio samples
+ passed via the input and output parameters.
+
+ The PortAudio stream callback runs at very high or real-time priority.
+ It is required to consistently meet its time deadlines. Do not allocate
+ memory, access the file system, call library functions or call other functions
+ from the stream callback that may block or take an unpredictable amount of
+ time to complete.
+
+ In order for a stream to maintain glitch-free operation the callback
+ must consume and return audio data faster than it is recorded and/or
+ played. PortAudio anticipates that each callback invocation may execute for
+ a duration approaching the duration of frameCount audio frames at the stream
+ sample rate. It is reasonable to expect to be able to utilise 70% or more of
+ the available CPU time in the PortAudio callback. However, due to buffer size
+ adaption and other factors, not all host APIs are able to guarantee audio
+ stability under heavy CPU load with arbitrary fixed callback buffer sizes.
+ When high callback CPU utilisation is required the most robust behavior
+ can be achieved by using paFramesPerBufferUnspecified as the

+ returned the callback will not be called again. If paAbort is returned the
+ stream will finish as soon as possible. If paComplete is returned, the stream
+ will continue until all buffers generated by the callback have been played.
+ This may be useful in applications such as soundfile players where a specific
+ duration of output is required. However, it is not necessary to utilize this
