1 # OpenAL config file. Options that are not under a block or are under the

5 # The system-wide settings can be put in /etc/openal/alsoft.conf and user-

7 # For Windows, these settings should go into %AppData%\alsoft.ini
8 # The environment variable ALSOFT_CONF can be used to specify another config
11 # Option and block names are case-insenstive. The supplied values are only
12 # hints and may not be honored (though generally it'll try to get as close as
13 # possible). These are the current available settings:
15 format = AL_FORMAT_STEREO16 # Sets the output format. Can be one of:
16 # AL_FORMAT_MONO8 (8-bit mono)
17 # AL_FORMAT_STEREO8 (8-bit stereo)
18 # AL_FORMAT_QUAD8 (8-bit 4-channel)
19 # AL_FORMAT_51CHN8 (8-bit 5.1 output)
20 # AL_FORMAT_61CHN8 (8-bit 6.1 output)
21 # AL_FORMAT_71CHN8 (8-bit 7.1 output)
22 # AL_FORMAT_MONO16 (16-bit mono)
23 # AL_FORMAT_STEREO16 (16-bit stereo)
24 # AL_FORMAT_QUAD16 (16-bit 4-channel)
25 # AL_FORMAT_51CHN16 (16-bit 5.1 output)
26 # AL_FORMAT_61CHN16 (16-bit 6.1 output)
27 # AL_FORMAT_71CHN16 (16-bit 7.1 output)
28 # Default is AL_FORMAT_STEREO16
30 cf_level = 0 # Sets the crossfeed level for stereo output. Valid values are:
33 # 2 - Middle crossfeed
34 # 3 - High crossfeed (virtual speakers are closer to itself)
35 # 4 - Low easy crossfeed
36 # 5 - Middle easy crossfeed
37 # 6 - High easy crossfeed
38 # Default is 0. Users of headphones may want to try various
39 # settings. Has no effect on non-stereo modes.
41 frequency = 44100 # Sets the output frequency. Default is 44100
43 refresh = 4096 # Sets the buffer size, in frames. Default is 4096. Note that
44 # the actual granularity may or may not be less than this.
46 sources = 256 # Sets the maximum number of allocatable sources. Lower values
47 # may help for systems with apps that try to play more sounds
48 # than the CPU can handle. Default is 256
50 stereodup = # Sets whether to duplicate stereo sounds on the rear speakers for
51 # 4+ channel output. This can make stereo sources substantially
52 # louder than mono or even 4+ channel sources, but provides a
53 # "fuller" playback quality. True, yes, on, and non-0 values will
54 # duplicate stereo sources. 0 and anything else will cause stereo
55 # sounds to only play out the front speakers.
58 drivers = # Sets the backend driver list order, comma-seperated. Unknown
59 # backends and duplicated names are ignored, and unlisted backends
60 # won't be considered for use. An empty list means the default.
62 # alsa,oss,solaris,dsound,winmm,sdl,wave
64 excludefx = # Sets which effects to exclude, preventing apps from using them.
65 # This can help for apps that try to use effects which are too CPU
66 # intensive for the system to handle. Available effects are:
68 # Default is empty (all available effects enabled)
70 [alsa] # ALSA backend stuff
71 device = default # Sets the device name for the default playback device.
74 periods = 0 # Sets the number of update buffers for playback. A value of 0
75 # means auto-select. Default is 0
77 capture = default # Sets the device name for the default capture device.
80 mmap = true # Sets whether to try using mmap mode (helps reduce latencies and
81 # CPU consumption). If mmap isn't available, it will automatically
82 # fall back to non-mmap mode. True, yes, on, and non-0 values will
83 # attempt to use mmap. 0 and anything else will force mmap off.
86 [oss] # OSS backend stuff
87 device = /dev/dsp # Sets the device name for OSS output. Default is /dev/dsp
89 periods = 4 # Sets the number of update buffers. Default is 4
91 capture = /dev/dsp # Sets the device name for OSS capture. Default is /dev/dsp
93 [solaris] # Solaris backend stuff
94 device = /dev/audio # Sets the device name for Solaris output. Default is
97 [dsound] # DirectSound backend stuff
98 periods = 4 # Sets the number of updates for the output buffer. Default is 4
100 [winmm] # Windows Multimedia backend stuff
103 [sdl] # SDL backend stuff
106 [wave] # Wave File Writer stuff
107 file = # Sets the filename of the wave file to write to. An empty name
108 # prevents the backend from opening, even when explicitly requested.
109 # THIS WILL OVERWRITE EXISTING FILES WITHOUT QUESTION!
