[ENUM]
[
    [DESCRIPTION]   
    These output types are used with System::setOutput / System::getOutput, to choose which output method to use.
  
    [REMARKS]
    To pass information to the driver when initializing fmod use the *extradriverdata* parameter in System::init for the following reasons.

    - FMOD_OUTPUTTYPE_WAVWRITER     - extradriverdata is a pointer to a char * file name that the wav writer will output to.
    - FMOD_OUTPUTTYPE_WAVWRITER_NRT - extradriverdata is a pointer to a char * file name that the wav writer will output to.
    - FMOD_OUTPUTTYPE_DSOUND        - extradriverdata is cast to a HWND type, so that FMOD can set the focus on the audio for a particular window.
    - FMOD_OUTPUTTYPE_PS3           - extradriverdata is a pointer to a FMOD_PS3_EXTRADRIVERDATA struct. This can be found in fmodps3.h.
    - FMOD_OUTPUTTYPE_XAUDIO        - (Xbox360) extradriverdata is a pointer to a FMOD_360_EXTRADRIVERDATA struct. This can be found in fmodxbox360.h.

    Currently these are the only FMOD drivers that take extra information.  Other unknown plugins may have different requirements.

    Note! If FMOD_OUTPUTTYPE_WAVWRITER_NRT or FMOD_OUTPUTTYPE_NOSOUND_NRT are used, and if the System::update function is being called
    very quickly (ie for a non realtime decode) it may be being called too quickly for the FMOD streamer thread to respond to.
    The result will be a skipping/stuttering output in the captured audio.

    To remedy this, disable the FMOD streamer thread, and use FMOD_INIT_STREAM_FROM_UPDATE to avoid skipping in the output stream,
    as it will lock the mixer and the streamer together in the same thread.

[ENUM]
[
    [DESCRIPTION]   
    These are speaker types defined for use with the System::setSoftwareFormat command.

    [REMARKS]
    Note below the phrase 'sound channels' is used.  These are the subchannels inside a sound, they are not related and 
    have nothing to do with the FMOD class "Channel".<br>
    For example a mono sound has 1 sound channel, a stereo sound has 2 sound channels, and an AC3 or 6 channel wav file have 6 "sound channels".<br>
    <br>
    FMOD_SPEAKERMODE_RAW<br>
    ---------------------<br>
    This mode is for output devices that are not specifically mono/stereo/quad/surround/5.1 or 7.1, but are multichannel.<br>
    Use System::setSoftwareFormat to specify the number of speakers you want to address, otherwise it will default to 2 (stereo).<br>
    Sound channels map to speakers sequentially, so a mono sound maps to output speaker 0, stereo sound maps to output speaker 0 & 1.<br>
    The user assumes knowledge of the speaker order.  FMOD_SPEAKER enumerations may not apply, so raw channel indices should be used.<br>
    Multichannel sounds map input channels to output channels 1:1. <br>
    Channel::setPan and Channel::setPanLevels do not work.<br>
    Speaker levels must be manually set with Channel::setPanMatrix.<br>
    <br>
    FMOD_SPEAKERMODE_MONO<br>
    ---------------------<br>
    This mode is for a 1 speaker arrangement.<br>
    Panning does not work in this speaker mode.<br>
    Mono, stereo and multichannel sounds have each sound channel played on the one speaker unity.<br>
    Mix behavior for multichannel sounds can be set with Channel::setPanMatrix.<br>
    Channel::setPanLevels does not work.<br>
    <br>
    FMOD_SPEAKERMODE_STEREO<br>
    -----------------------<br>
    This mode is for 2 speaker arrangements that have a left and right speaker.<br>
    <li>Mono sounds default to an even distribution between left and right.  They can be panned with Channel::setPan.<br>
    <li>Stereo sounds default to the middle, or full left in the left speaker and full right in the right speaker.  
    <li>They can be cross faded with Channel::setPan.<br>
    <li>Multichannel sounds have each sound channel played on each speaker at unity.<br>
    <li>Mix behavior for multichannel sounds can be set with Channel::setPanMatrix.<br>
    <li>Channel::setPanLevels works but only front left and right parameters are used, the rest are ignored.<br>
    <br>
    FMOD_SPEAKERMODE_QUAD<br>
    ------------------------<br>
    This mode is for 4 speaker arrangements that have a front left, front right, surround left and a surround right speaker.<br>
    <li>Mono sounds default to an even distribution between front left and front right.  They can be panned with Channel::setPan.<br>
    <li>Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.<br>
    <li>They can be cross faded with Channel::setPan.<br>
    <li>Multichannel sounds default to all of their sound channels being played on each speaker in order of input.<br>
    <li>Mix behavior for multichannel sounds can be set with Channel::setPanMatrix.<br>
    <li>Channel::setPanLevels works but rear left, rear right, center and lfe are ignored.<br>
    <br>
    FMOD_SPEAKERMODE_SURROUND<br>
    ------------------------<br>
    This mode is for 5 speaker arrangements that have a left/right/center/surround left/surround right.<br>
    <li>Mono sounds default to the center speaker.  They can be panned with Channel::setPan.<br>
    <li>Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.  
    <li>They can be cross faded with Channel::setPan.<br>
    <li>Multichannel sounds default to all of their sound channels being played on each speaker in order of input.  
    <li>Mix behavior for multichannel sounds can be set with Channel::setPanMatrix.<br>
    <li>Channel::setPanLevels works but rear left / rear right are ignored.<br>
    <br>
    FMOD_SPEAKERMODE_5POINT1<br>
    ---------------------------------------------------------<br>
    This mode is for 5.1 speaker arrangements that have a left/right/center/surround left/surround right and a subwoofer speaker.<br>
    <li>Mono sounds default to the center speaker.  They can be panned with Channel::setPan.<br>
    <li>Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.  
    <li>They can be cross faded with Channel::setPan.<br>
    <li>Multichannel sounds default to all of their sound channels being played on each speaker in order of input.  
    <li>Mix behavior for multichannel sounds can be set with Channel::setPanMatrix.<br>
    <li>Channel::setPanLevels works but rear left / rear right are ignored.<br>
    <br>
    FMOD_SPEAKERMODE_7POINT1<br>
    ------------------------<br>
    This mode is for 7.1 speaker arrangements that have a left/right/center/surround left/surround right/rear left/rear right 
    and a subwoofer speaker.<br>
    <li>Mono sounds default to the center speaker.  They can be panned with Channel::setPan.<br>
    <li>Stereo sounds default to the left sound channel played on the front left, and the right sound channel played on the front right.  
    <li>They can be cross faded with Channel::setPan.<br>
    <li>Multichannel sounds default to all of their sound channels being played on each speaker in order of input.  
    <li>Mix behavior for multichannel sounds can be set with Channel::setPanMatrix.<br>
    <li>Channel::setPanLevels works and every parameter is used to set the balance of a sound in any speaker.<br>

    FMOD_MODE

    [DESCRIPTION]   
    Sound description bitfields, bitwise OR them together for loading and describing sounds.

    [REMARKS]
    By default a sound will open as a static sound that is decompressed fully into memory to PCM. (ie equivalent of FMOD_CREATESAMPLE)<br>
    To have a sound stream instead, use FMOD_CREATESTREAM, or use the wrapper function System::createStream.<br>
    Some opening modes (ie FMOD_OPENUSER, FMOD_OPENMEMORY, FMOD_OPENMEMORY_POINT, FMOD_OPENRAW) will need extra information.<br>
    This can be provided using the FMOD_CREATESOUNDEXINFO structure.
    <br>
    Specifying FMOD_OPENMEMORY_POINT will POINT to your memory rather allocating its own sound buffers and duplicating it internally.<br>
    <b><u>This means you cannot free the memory while FMOD is using it, until after Sound::release is called.</b></u>
    With FMOD_OPENMEMORY_POINT, for PCM formats, only WAV, FSB, and RAW are supported.  For compressed formats, only those formats supported by FMOD_CREATECOMPRESSEDSAMPLE are supported.<br>
    With FMOD_OPENMEMORY_POINT and FMOD_OPENRAW or PCM, if using them together, note that you must pad the data on each side by 16 bytes.  This is so fmod can modify the ends of the data for looping/interpolation/mixing purposes.  If a wav file, you will need to insert silence, and then reset loop points to stop the playback from playing that silence.<br>
    <br>
    <b>Xbox 360 memory</b> On Xbox 360 Specifying FMOD_OPENMEMORY_POINT to a virtual memory address will cause FMOD_ERR_INVALID_ADDRESS
    to be returned.  Use physical memory only for this functionality.<br>
    <br>
    FMOD_LOWMEM is used on a sound if you want to minimize the memory overhead, by having FMOD not allocate memory for certain 
    features that are not likely to be used in a game environment.  These are :<br>
    1. Sound::getName functionality is removed.  256 bytes per sound is saved.<br>

    FMOD_SYSTEM_CALLBACK_TYPE

    [DESCRIPTION]   
    These callback types are used with System::setCallback.

    [REMARKS]
    Each callback has commanddata parameters passed as void* unique to the type of callback.<br>
    See reference to FMOD_SYSTEM_CALLBACK to determine what they might mean for each type of callback.<br>
    <br>
    <b>Note!</b> Using FMOD_SYSTEM_CALLBACK_DEVICELISTCHANGED (Windows only) will disable any automated device ejection/insertion handling by FMOD.  Use this callback to control the behaviour yourself.<br>
    <br>
    <b>Note!</b> Using FMOD_SYSTEM_CALLBACK_DEVICELISTCHANGED (on Mac only) requires the application to be running an event loop which will allow external changes to device list to be detected by FMOD.<br>
    <br>
    <b>Note!</b> The 'system' object pointer will be null for FMOD_SYSTEM_CALLBACK_MEMORYALLOCATIONFAILED callback.

    [DESCRIPTION]   
    List of connection types between 2 DSP nodes.

    [REMARKS]
    FMOD_DSP_CONNECTION_TYPE_STANDARD<br>
    ----------------------------------<br>
    Default DSPConnection type.  Audio is mixed from the input to the output DSP's audible buffer, meaning it will be part of the audible signal.  A standard connection will execute its input DSP if it has not been executed before.<br>
    <br>
    FMOD_DSP_CONNECTION_TYPE_SIDECHAIN<br>
    ----------------------------------<br>
    Sidechain DSPConnection type.  Audio is mixed from the input to the output DSP's sidechain buffer, meaning it will NOT be part of the audible signal.  A sidechain connection will execute its input DSP if it has not been executed before.<br>
    The purpose of the seperate sidechain buffer in a DSP, is so that the DSP effect can privately access for analysis purposes.  An example of use in this case, could be a compressor which analyzes the signal, to control its own effect parameters (ie a compression level or gain).<br>
    <br>
    For the effect developer, to accept sidechain data, the sidechain data will appear in the FMOD_DSP_STATE struct which is passed into the read callback of a DSP unit.<br>
    FMOD_DSP_STATE::sidechaindata and FMOD_DSP::sidechainchannels will hold the mixed result of any sidechain data flowing into it.<br>
    <br>
    FMOD_DSP_CONNECTION_TYPE_SEND<br>
    -----------------------------<br>
    Send DSPConnection type.  Audio is mixed from the input to the output DSP's audible buffer, meaning it will be part of the audible signal.  A send connection will NOT execute its input DSP if it has not been executed before.<br>
    A send connection will only read what exists at the input's buffer at the time of executing the output DSP unit (which can be considered the 'return')<br>
    <br>

[STRUCTURE] 
[
    [DESCRIPTION]
    Use this structure with System::createSound when more control is needed over loading.
    The possible reasons to use this with System::createSound are:

    - Loading a file from memory.
    - Loading a file from within another larger (possibly wad/pak) file, by giving the loader an offset and length.
    - To create a user created / non file based sound.
    - To specify a starting subsound to seek to within a multi-sample sounds (ie FSB/DLS) when created as a stream.
    - To specify which subsounds to load for multi-sample sounds (ie FSB/DLS) so that memory is saved and only a subset is actually loaded/read from disk.
    - To specify 'piggyback' read and seek callbacks for capture of sound data as fmod reads and decodes it.  Useful for ripping decoded PCM data from sounds as they are loaded / played.
    - To specify a MIDI DLS sample set file to load when opening a MIDI file.

    See below on what members to fill for each of the above types of sound you want to create.

    [REMARKS]
    This structure is optional!  Specify 0 or NULL in System::createSound if you don't need it!

    <u>Loading a file from memory.</u>

    - Create the sound using the FMOD_OPENMEMORY flag.
    - Mandatory.  Specify 'length' for the size of the memory block in bytes.
    - Other flags are optional.

    <u>Loading a file from within another larger (possibly wad/pak) file, by giving the loader an offset and length.</u>

    - Mandatory.  Specify 'fileoffset' and 'length'.
    - Other flags are optional.

    <u>To create a user created / non file based sound.</u>

    - Create the sound using the FMOD_OPENUSER flag.
    - Mandatory.  Specify 'defaultfrequency, 'numchannels' and 'format'.
    - Other flags are optional.

    <u>To specify a starting subsound to seek to and flush with, within a multi-sample stream (ie FSB/DLS).</u>

    - Mandatory.  Specify 'initialsubsound'.

    <u>To specify which subsounds to load for multi-sample sounds (ie FSB/DLS) so that memory is saved and only a subset is actually loaded/read from disk.</u>

    - Mandatory.  Specify 'inclusionlist' and 'inclusionlistnum'.

    <u>To specify 'piggyback' read and seek callbacks for capture of sound data as fmod reads and decodes it.  Useful for ripping decoded PCM data from sounds as they are loaded / played.</u>

    - Mandatory.  Specify 'pcmreadcallback' and 'pcmseekcallback'.

    <u>To specify a MIDI DLS sample set file to load when opening a MIDI file.</u>

    - Mandatory.  Specify 'dlsname'.

    Setting the 'decodebuffersize' is for cpu intensive codecs that may be causing stuttering, not file intensive codecs (ie those from CD or netstreams) which are normally 
    altered with System::setStreamBufferSize.  As an example of cpu intensive codecs, an mp3 file will take more cpu to decode than a PCM wav file.

    If you have a stuttering effect, then it is using more cpu than the decode buffer playback rate can keep up with.  Increasing the decode buffersize will most likely solve this problem.

    FSB codec.  If inclusionlist and numsubsounds are used together, this will trigger a special mode where subsounds are shuffled down to save memory.  (useful for large FSB 
    files where you only want to load 1 sound).  There will be no gaps, ie no null subsounds.  As an example, if there are 10,000 subsounds and there is an inclusionlist with only 1 entry, 
    and numsubsounds = 1, then subsound 0 will be that entry, and there will only be the memory allocated for 1 subsound.  Previously there would still be 10,000 subsound pointers and other
    associated codec entries allocated along with it multiplied by 10,000.

    Members marked with [r] mean the variable is modified by FMOD and is for reading purposes only.  Do not change this value.<br>
    Members marked with [w] mean the variable can be written to.  The user can set the value.

[STRUCTURE] 
[
    [DESCRIPTION]
    Settings for advanced features like configuring memory and cpu usage for the FMOD_CREATECOMPRESSEDSAMPLE feature.

    [REMARKS]
    maxMPEGCodecs / maxADPCMCodecs / maxXMACodecs will determine the maximum cpu usage of playing realtime samples.  Use this to lower potential excess cpu usage and also control memory usage.<br>
    <br>
    maxPCMCodecs is for use with PS3 only. It will determine the maximum number of PCM voices that can be played at once. This includes streams of any format and all sounds created
    *without* the FMOD_CREATECOMPRESSEDSAMPLE flag.
    <br>
    Memory will be allocated for codecs 'up front' (during System::init) if these values are specified as non zero.  If any are zero, it allocates memory for the codec whenever a file of the type in question is loaded.  So if maxMPEGCodecs is 0 for example, it will allocate memory for the mpeg codecs the first time an mp3 is loaded or an mp3 based .FSB file is loaded.<br>
    <br>
    Due to inefficient encoding techniques on certain .wav based ADPCM files, FMOD can can need an extra 29720 bytes per codec.  This means for lowest memory consumption.  Use FSB as it uses an optimal/small ADPCM block size.<br>
    <br>
    Members marked with [r] mean the variable is modified by FMOD and is for reading purposes only.  Do not change this value.<br>
    Members marked with [w] mean the variable can be written to.  The user can set the value.<br>
    Members marked with [r/w] are either read or write depending on if you are using System::setAdvancedSettings (w) or System::getAdvancedSettings (r).
