39 # Sets the crossfeed level for stereo output. Valid values are:
42 # 2 - Middle crossfeed
43 # 3 - High crossfeed (virtual speakers are closer to itself)
44 # 4 - Low easy crossfeed
45 # 5 - Middle easy crossfeed

52 # Sets the amount of dampening on sounds emanating from behind the listener.
53 # This is used to simulate the natural occlusion of the head, which is
54 # typically missing with mono and stereo output, and as such, only works on
55 # mono and stereo output modes. Valid values range from 0 to 1 (inclusive),
56 # and higher values provide a stronger effect.
60 # Sets the output frequency.
64 # Sets real-time priority for the mixing thread. Not all drivers may use this
65 # (eg. PulseAudio) as they already control the priority of the mixing thread.
66 # 0 and negative values will disable it. Note that this may constitute a
67 # security risk since a real-time priority thread can indefinitely block
68 # normal-priority threads if it fails to wait. As such, the default is
73 # Sets the update period size, in frames. This is the number of frames needed
74 # for each mixing update. If the deprecated 'refresh' option is specified and
75 # this isn't, the value will be calculated as size = refresh/periods.
79 # Sets the number of update periods. Higher values create a larger mix ahead,
80 # which helps protect against skips when the CPU is under load, but increases
81 # the delay between a sound getting mixed and being heard.
85 # Sets the maximum number of allocatable sources. Lower values may help for
86 # systems with apps that try to play more sounds than the CPU can handle.
90 # Sets whether to duplicate stereo sounds on the rear and side speakers for 4+
91 # channel output. This can make stereo sources substantially louder than mono
92 # or even 4+ channel sources, but provides a "fuller" playback quality. True,
93 # yes, on, and non-0 values will duplicate stereo sources. 0 and anything else
94 # will cause stereo sounds to only play out the front speakers.
98 # Sets the backend driver list order, comma-seperated. Unknown backends and
99 # duplicated names are ignored. Unlisted backends won't be considered for use
100 # unless the list is ended with a comma (eg. 'oss,' will list OSS first

108 # system to handle. Available effects are: eaxreverb,reverb,echo
112 # Sets the maximum number of Auxiliary Effect Slots an app can create. A slot
113 # can use a non-negligible amount of CPU time if an effect is set on it even
114 # if no sources are feeding it, so this may help when apps use more than the

120 # sends possible is defined at compile time and thus can not be increased
121 # beyond the default (2).
125 # Sets the speaker layout when using stereo output. Values are specified in
126 # degrees, where 0 is straight in front, negative goes left, and positive goes
127 # right. The values must define a circular pattern, starting with the back-
128 # left at the most negative, around the front to back-center. Unspecified

162 # Sets the device name for the default playback device.
166 # Sets the device name for the default capture device.
170 # Sets whether to try using mmap mode (helps reduce latencies and CPU
171 # consumption). If mmap isn't available, it will automatically fall back to
172 # non-mmap mode. True, yes, on, and non-0 values will attempt to use mmap. 0
173 # and anything else will force mmap off.

195 # Sets the device name for Solaris output.
199 ## DirectSound backend stuff
204 ## Windows Multimedia backend stuff
209 ## PortAudio backend stuff
214 # Sets the device index for output. Negative values will use the default as
215 # given by PortAudio itself.

229 # Sets the filename of the wave file to write to. An empty name prevents the
