For Windows users, there are two different types of modes that change the way the Aurora
input and output channels are presented to applications that use MME or DirectSound driver
models. Some modes present the I/O as 8-channel devices, and other modes present the I/O
as multiple stereo devices. The modes that present multi-channel devices are the appropriate
choice for playback of multi-channel interleaved audio (i.e. 5.1 or 7.1 surround sound).
Modes using stereo devices are the appropriate choice for contexts where independent access
to pairs of input and output channels are required. The following table describes how the
devices are present for each mode in Windows:
Mode Device Input Name Output Name
1M 1 Aurora Analog In 1-8 Aurora Analog Out 1-8
1S
1 Aurora Analog In 1/2 Aurora Analog Out 1/2
2 Aurora Analog In 3/4 Aurora Analog Out 3/4
3 Aurora Analog In 5/6 Aurora Analog Out 5/6
4 Aurora Analog In 7/8 Aurora Analog Out 7/8

This characteristic is most relevant for Windows multimedia applications. Most Pro Audio
applications running Windows use ASIO as the driver model, and Core Audio in OS X.
When ASIO or Core Audio is used, the available I/O is always presented as multiple mono
channels (this is the reason multi-channel modes are not available in OS X). For ASIO and
OS X, the channel modes selected only determine the number and type of I/O that will be
