/*
|
||||
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 specifying '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.
|
||||
|
||||
8.24 format:
|
||||
|
||||
If paCustomFormat is specified as sample format then the implementation will understand it
|
||||
as valid 24-bits inside 32-bit container (e.g. wBitsPerSample = 32, Samples.wValidBitsPerSample = 24).
|
||||
|
||||
By using paCustomFormat there will be small optimization when samples are be copied
|
||||
with Copy_24_To_24 by PA processor instead of conversion from packed 3-byte (24-bit) data
|
||||
with Int24_To_Int32.
|
||||
|
||||
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.
|
||||
|
||||
If paWinWasapiExplicitSampleFormat flag is provided then implementation will not try to select
|
||||
suitable close format and will return an error instead of paFormatIsSupported. By specifying
|
||||
paWinWasapiExplicitSampleFormat flag it is possible to find out what sample formats are
|
||||
supported by Exclusive or Shared modes.
|
||||
|
||||
Pa_OpenStream:
|
||||
|
||||
To set desired Share Mode (Exclusive/Shared) you must supply
|
||||
PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
|
||||
PaStreamParameters::hostApiSpecificStreamInfo structure.
|
||||
|
||||
Coding style for parameters and structure members of the public API:
|
||||
|
||||
1) bXXX - boolean, [1 (TRUE), 0 (FALSE)]
|
||||
2) pXXX - pointer
|
||||
3) fnXXX - pointer to function
|
||||
4) structure members are never prefixed with a type distinguisher
|
||||
|
||||
|
||||
UWP/WinRT:
|
||||
|
||||
This platform has number of limitations which do not allow to enumerate audio devices without
|
||||
an additional external help. Enumeration is possible though from C++/CX, check the related API
|
||||
Windows::Devices::Enumeration::DeviceInformation::FindAllAsync().
|
||||
|
||||
The main limitation is an absence of the device enumeration from inside the PA's implementation.
|
||||
This problem can be solved by using the following functions:
|
||||
|
||||
PaWasapiWinrt_SetDefaultDeviceId() - to set default input/output device,
|
||||
PaWasapiWinrt_PopulateDeviceList() - to populate device list with devices.
|
||||
|
||||
Here is an example of populating the device list which can also be updated dynamically depending on
|
||||
whether device was removed from or added to the system:
|
||||
|
||||
----------------
|
||||
|
||||
std::vector<const UINT16 *> ids, names;
|
||||
std::vector<PaWasapiDeviceRole> role;
|
||||
|
||||
ids.resize(count);
|
||||
names.resize(count);
|
||||
role.resize(count);
|
||||
|
||||
for (UINT32 i = 0; i < count; ++i)
|
||||
{
|
||||
ids[i] = (const UINT16 *)device_ids[i].c_str();
|
||||
names[i] = (const UINT16 *)device_names[i].c_str();
|
||||
role[i] = eRoleUnknownFormFactor;
|
||||
}
|
||||
|
||||
PaWasapiWinrt_SetDefaultDeviceId((const UINT16 *)default_device_id.c_str(), !capture);
|
||||
PaWasapiWinrt_PopulateDeviceList(ids.data(), names.data(), role.data(), count, !capture);
|
||||
PaWasapi_UpdateDeviceList();
|
||||
|
||||
