Now working on gcc4.8, x86-64 on windows 

Had to make my own portaudio and rtl-sdr binaries. The available
packages weren't compatible somehow.  Also wxWidgets wxPack doesn't
include OpenGL support but it's easy enough to compile.

# CMakeParseArguments
# -------------------
#
#
#
# CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
# <multi_value_keywords> args...)
#
# CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
# for parsing the arguments given to that macro or function. It
# processes the arguments and defines a set of variables which hold the
# values of the respective options.
#
# The <options> argument contains all options for the respective macro,
# i.e. keywords which can be used when calling the macro without any
# value following, like e.g. the OPTIONAL keyword of the install()
# command.
#
# The <one_value_keywords> argument contains all keywords for this macro
# which are followed by one value, like e.g. DESTINATION keyword of the
# install() command.
#
# The <multi_value_keywords> argument contains all keywords for this
# macro which can be followed by more than one value, like e.g. the
# TARGETS or FILES keywords of the install() command.
#
# When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
# keywords listed in <options>, <one_value_keywords> and
# <multi_value_keywords> a variable composed of the given <prefix>
# followed by "_" and the name of the respective keyword. These
# variables will then hold the respective value from the argument list.
# For the <options> keywords this will be TRUE or FALSE.
#
# All remaining arguments are collected in a variable
# <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
# whether your macro was called with unrecognized parameters.
#
# As an example here a my_install() macro, which takes similar arguments
# as the real install() command:
#
# ::
#
# function(MY_INSTALL)
# set(options OPTIONAL FAST)
# set(oneValueArgs DESTINATION RENAME)
# set(multiValueArgs TARGETS CONFIGURATIONS)
# cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}"
# "${multiValueArgs}" ${ARGN} )
# ...
#
#
#
# Assume my_install() has been called like this:
#
# ::
#
# my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)
#
#
#
# After the cmake_parse_arguments() call the macro will have set the
# following variables:
#
# ::
#
# MY_INSTALL_OPTIONAL = TRUE
# MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
# MY_INSTALL_DESTINATION = "bin"
# MY_INSTALL_RENAME = "" (was not used)
# MY_INSTALL_TARGETS = "foo;bar"
# MY_INSTALL_CONFIGURATIONS = "" (was not used)
# MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"
#
#
#
# You can then continue and process these variables.
#
# Keywords terminate lists of values, e.g. if directly after a
# one_value_keyword another recognized keyword follows, this is
# interpreted as the beginning of the new option. E.g.
# my_install(TARGETS foo DESTINATION OPTIONAL) would result in
# MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
# would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

#.rst:
# FindPackageHandleStandardArgs
# -----------------------------
#
#
#
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... )
#
# This function is intended to be used in FindXXX.cmake modules files.
# It handles the REQUIRED, QUIET and version-related arguments to
# find_package(). It also sets the <packagename>_FOUND variable. The
# package is considered found if all variables <var1>... listed contain
# valid results, e.g. valid filepaths.
#
# There are two modes of this function. The first argument in both
# modes is the name of the Find-module where it is called (in original
# casing).
#
# The first simple mode looks like this:
#
# ::
#
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name>
# (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )
#
# If the variables <var1> to <varN> are all valid, then
# <UPPERCASED_NAME>_FOUND will be set to TRUE. If DEFAULT_MSG is given
# as second argument, then the function will generate itself useful
# success and error messages. You can also supply a custom error
# message for the failure case. This is not recommended.
#
# The second mode is more powerful and also supports version checking:
#
# ::
#
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME
# [FOUND_VAR <resultVar>]
# [REQUIRED_VARS <var1>...<varN>]
# [VERSION_VAR <versionvar>]
# [HANDLE_COMPONENTS]
# [CONFIG_MODE]
# [FAIL_MESSAGE "Custom failure message"] )
#
# In this mode, the name of the result-variable can be set either to
# either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the
# FOUND_VAR option. Other names for the result-variable are not
# allowed. So for a Find-module named FindFooBar.cmake, the two
# possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended
# to use the original case version. If the FOUND_VAR option is not
# used, the default is <UPPERCASED_NAME>_FOUND.
#
# As in the simple mode, if <var1> through <varN> are all valid,
# <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the
# variables which are required for this package are listed. Following
# VERSION_VAR the name of the variable can be specified which holds the
# version of the package which has been found. If this is done, this
# version will be checked against the (potentially) specified required
# version used in the find_package() call. The EXACT keyword is also
# handled. The default messages include information about the required
# version and the version which has been actually found, both if the
# version is ok or not. If the package supports components, use the
# HANDLE_COMPONENTS option to enable handling them. In this case,
# find_package_handle_standard_args() will report which components have
# been found and which are missing, and the <packagename>_FOUND variable
# will be set to FALSE if any of the required components (i.e. not the
# ones listed after OPTIONAL_COMPONENTS) are missing. Use the option
# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
# find_package(... NO_MODULE) call. In this case VERSION_VAR will be
# set to <NAME>_VERSION and the macro will automatically check whether
# the Config module was found. Via FAIL_MESSAGE a custom failure
# message can be specified, if this is not used, the default message
# will be displayed.
#
# Example for mode 1:
#
# ::
#
# find_package_handle_standard_args(LibXml2 DEFAULT_MSG
# LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
#
#
#
# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
# LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to
# TRUE. If it is not found and REQUIRED was used, it fails with
# FATAL_ERROR, independent whether QUIET was used or not. If it is
# found, success will be reported, including the content of <var1>. On
# repeated Cmake runs, the same message won't be printed again.
#
# Example for mode 2:
#
# ::
#
# find_package_handle_standard_args(LibXslt
# FOUND_VAR LibXslt_FOUND
# REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
# VERSION_VAR LibXslt_VERSION_STRING)
#
# In this case, LibXslt is considered to be found if the variable(s)
# listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and
# LibXslt_INCLUDE_DIRS in this case. The result will then be stored in
# LibXslt_FOUND . Also the version of LibXslt will be checked by using
# the version contained in LibXslt_VERSION_STRING. Since no
# FAIL_MESSAGE is given, the default messages will be printed.
#
# Another example for mode 2:
#
# ::
#
# find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
# find_package_handle_standard_args(Automoc4 CONFIG_MODE)
#
# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
# NO_MODULE) and adds an additional search directory for automoc4. Here
# the result will be stored in AUTOMOC4_FOUND. The following
# FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
# success/error message.

@brief Allocation Group prototypes. An Allocation Group makes it easy to
allocate multiple blocks of memory and free them all at once.
An allocation group is useful for keeping track of multiple blocks
of memory which are allocated at the same time (such as during initialization)
and need to be deallocated at the same time. The allocation group maintains
a list of allocated blocks, and can free all allocations at once. This
can be usefull for cleaning up after a partially initialized object fails.
The allocation group implementation is built on top of the lower
level allocation functions defined in pa_util.h

PaSampleFormat inputParameters->sampleFormat
- is one of the sample formats defined in portaudio.h
void *inputParameters->hostApiSpecificStreamInfo
- if supplied its hostApi field matches the input device's host Api
PaDeviceIndex outputParmeters->device
- is within range (0 to Pa_CountDevices-1)

- upper bound is NOT validated against device capabilities
PaSampleFormat outputParmeters->sampleFormat
- is one of the sample formats defined in portaudio.h
void *outputParmeters->hostApiSpecificStreamInfo

double sampleRate
- is not an 'absurd' rate (less than 1000. or greater than 384000.)

PaStreamFlags streamFlags
- unused platform neutral flags are zero
- paNeverDropInput is only used for full-duplex callback streams
with variable buffer size (paFramesPerBufferUnspecified)
[*END PA FRONT VALIDATIONS*]
The following validations MUST be performed by (*OpenStream)():
- check that input device can support numInputChannels
- check that input device can support inputSampleFormat, or that
we have the capability to convert from outputSampleFormat to
a native format
- if inputStreamInfo is supplied, validate its contents,
or return an error if no inputStreamInfo is expected
- check that output device can support numOutputChannels
- check that output device can support outputSampleFormat, or that
we have the capability to convert from outputSampleFormat to
a native format
- if outputStreamInfo is supplied, validate its contents,
or return an error if no outputStreamInfo is expected
- if a full duplex stream is requested, check that the combination
of input and output parameters is supported
- check that the device supports sampleRate
- alter sampleRate to a close allowable rate if necessary
- validate inputLatency and outputLatency
- validate any platform specific flags, if flags are supplied they
must be valid.

@brief Buffer Processor prototypes. A Buffer Processor performs buffer length
adaption, coordinates sample format conversion, and interleaves/deinterleaves
channels.
<h3>Overview</h3>
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.
<h4>Initialization, resetting and termination</h4>
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.
<h4>Using the buffer processor for a callback stream</h4>
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.
<h4>Using the buffer processor for a blocking read/write stream</h4>
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 <i>copy</i> 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 <i>copy</i> 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.

/** @file
@ingroup common_src
@brief Single-reader single-writer lock-free ring buffer
PaUtilRingBuffer is a ring buffer used to transport samples between
different execution contexts (threads, OS callbacks, interrupt handlers)
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.
