+ "MPEG-2" in the comments below refers to ISO/IEC 13818-7 (MPEG-2 AAC spec).
+ "MPEG-4" in the comments below refers to ISO/IEC 14496-3 (MPEG-4 Audio spec).
+
+ The following defines the format block to be used for MPEG-2 AAC or MPEG-4 HE-AAC v1/v2 streams.
+ When setting media type attributes in Media Foundation (MF) objects, this will appear in conjunction with major type MFMediaType_Audio and sub type MFAudioFormat_AAC (=MEDIASUBTYPE_MPEG_HEAAC).
+ The format block structure HEAACWAVEFORMAT is defined below.  It starts with the structure HEAACWAVEINFO (which is an extension of WAVEFORMATEX), followed by AudioSpecificConfig() as defined by ISO/IEC 14496-3 (MPEG-4 audio).
+ Since the length of AudioSpecificConfig() may vary from one stream to another, this is a variable size format block.
+
+ The WAVEFORMATEX fields describe the properties of the core AAC stream, without SBR/PS extensions (if exists). This is the description of the WAVEFORMATEX fields:
+
+ wfx.wFormatTag - Set this to WAVE_FORMAT_MPEG_HEAAC (0x1610).
+
+ wfx.nChannels - Total number of channels in core AAC stream (including LFE if exists).
+ This might be different than the decoded number of channels if the MPEG-4 Parametric Stereo (PS) tool exists. If unknown, set to zero.
+
+ wfx.nSamplesPerSec - Sampling rate of core AAC stream. This will be one of the 12 supported sampling rate between 8000 and 96000 Hz, as defined in MPEG-2.
+ This might be different than the decoded sampling rate if the MPEG-4 Spectral Band Replication (SBR) tool exists.
+ If not know in advance, the sampling rate can be extracted from:
+ - the 4-bit sampling_frequency_index field in adts_fixed_header(), or
+ - program_config_element() in adif_header for MPEG-2 streams, or
+ - the 4-bit samplingFrequencyIndex field in AudioSpecificConfig() for MPEG-4 streams.
+
+ wfx.nAvgBytesPerSec - The average bytes per second calculated based on the average bit rate of the compressed stream.
+ This value may be used by parsers to seek into a particular time offset in the stream. It may also be used by applications to determine roughly how much buffer length to allocate.
+ If this is not known in advance, this value can be estimated by parsing some (or all) of the compressed HE-AAC frames and calculating bit rate based on average compressed frame size.
+ If unknown, set to zero.
+
+ wfx.nBlockAlign - Set this to 1.
+
+ wfx.wBitsPerSample - Desired bit depth of the decoded PCM. If unknown, set to zero.
+
+ wfx.cbSize - Set this to 12 (=sizeof(HEAACWAVEINFO)-sizeof(WAVEFORMATEX)) plus the size of AudioSpecificConfig() in bytes.
+
+ ===================================
+
+How do we parse this format block? assume pbBuff is the address of the first byte in the format block. We do the following:
+
+pwfInfo := cast(^HEAACWAVEINFO)pbBuff
+
+if pwfInfo.wStructType == 0 {
+	pwf := cast(^HEAACWAVEFORMAT)pbBuff
+
+	// All HEAACWAVEFORMAT fields can now be accessed through pwf
+	// To parse AudioSpecificConfig(), write a function such as
+	// ParseAudioSpecificConfig :: proc(pbASC: ^BYTE, dwASCLen: DWORD),
+	// and call:
+
+	dwASCLen: DWORD = pwf.wfInfo.wfx.cbSize - size_of(HEAACWAVEINFO) + size_of(WAVEFORMATEX)
+
+	ParseAudioSpecificConfig(pwf.pbAudioSpecificConfig, dwASCLen)
+} else {
+	// Reserved
+}

+	// Defines core AAC properties. See description above. WAVEFORMATEX is of size 18 bytes.

+	// For example values 0x28-0x2B correspond to AAC Profile, values 0x2C-0x2F correspond to HE-AAC profile and 0x30-0x33 for HE-AAC v2 profile.
+	// If unknown, set to zero or 0xFE ("no audio profile specified").

+	//    wfx.cbSize will indicate the total length including AudioSpecificConfig().
+	//    Use HEAACWAVEFORMAT to gain easy access to the address of the first byte of AudioSpecificConfig() for parsing.
+	//    Typical values for the size of AudioSpecificConfig (ASC) are:
+	//    - 2 bytes for AAC or HE-AAC v1/v2 with implicit signaling of SBR,
+	//    - 5 bytes for HE-AAC v1 with explicit signaling of SBR,
+	//    - 7 bytes for HE-AAC v2 with explicit signaling of SBR and PS.
+	//    The size may be longer than 7 bytes if the 4-bit channelConfiguration field in ASC is zero, which means program_config_element() is present in ASC.
+	// All other codes are reserved.

+// Description: AudioClient stream flags
+// Can be a combination of AUDCLNT_STREAMFLAGS and AUDCLNT_SYSFXFLAGS:
+// AUDCLNT_STREAMFLAGS (this group of flags uses the high word, w/exception of high-bit which is reserved, 0x7FFF0000):
+//     AUDCLNT_STREAMFLAGS_CROSSPROCESS -             Audio policy control for this stream will be shared with with other process sessions that use the same audio session GUID.
+//     AUDCLNT_STREAMFLAGS_LOOPBACK -                 Initializes a renderer endpoint for a loopback audio application. In this mode, a capture stream will be opened on the specified renderer endpoint. Shared mode and a renderer endpoint is required.
+//                                                    Otherwise the IAudioClient.Initialize call will fail. If the initialize is successful, a capture stream will be available from the IAudioClient object.
+//     AUDCLNT_STREAMFLAGS_EVENTCALLBACK -            An exclusive mode client will supply an event handle that will be signaled when an IRP completes (or a waveRT buffer completes) telling it to fill the next buffer
+//     AUDCLNT_STREAMFLAGS_NOPERSIST -                Session state will not be persisted
+//     AUDCLNT_STREAMFLAGS_RATEADJUST -               The sample rate of the stream is adjusted to a rate specified by an application.
+//     AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY -      When used with AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM, a sample rate converter with better quality than the default conversion but with a higher performance cost is used.
+//                                                    This should be used if the audio is ultimately intended to be heard by humans as opposed to other scenarios such as pumping silence or populating a meter.
+//     AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM -           A channel matrixer and a sample rate converter are inserted as necessary to convert between the uncompressed format supplied to IAudioClient.Initialize and the audio engine mix format.
+//     AUDCLNT_SESSIONFLAGS_EXPIREWHENUNOWNED -       Session expires when there are no streams and no owning session controls.
+//     AUDCLNT_SESSIONFLAGS_DISPLAY_HIDE -            Don't show volume control in the Volume Mixer.
+//     AUDCLNT_SESSIONFLAGS_DISPLAY_HIDEWHENEXPIRED - Don't show volume control in the Volume Mixer after the session expires.
