1 # OpenAL config file. Options that are not under a block or are under the | |
2 # [general] block are for general, non-backend-specific options. Blocks may | |
3 # appear multiple times, and duplicated options will take the last value | |
4 # specified. | |
5 # The system-wide settings can be put in /etc/openal/alsoft.conf and user- | |
6 # specific override settings in ~/.alsoftrc. | |
7 # For Windows, these settings should go into %AppData%\alsoft.ini | |
8 # The environment variable ALSOFT_CONF can be used to specify another config | |
9 # override | |
10 | |
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). Note: options that are left unset may default to app- or system- | |
14 # specified values. These are the current available settings: | |
15 | |
16 ## format: | |
17 # Sets the output format. Can be one of: | |
18 # AL_FORMAT_MONO8 (8-bit mono) | |
19 # AL_FORMAT_STEREO8 (8-bit stereo) | |
20 # AL_FORMAT_QUAD8 (8-bit 4-channel) | |
21 # AL_FORMAT_51CHN8 (8-bit 5.1 output) | |
22 # AL_FORMAT_61CHN8 (8-bit 6.1 output) | |
23 # AL_FORMAT_71CHN8 (8-bit 7.1 output) | |
24 # AL_FORMAT_MONO16 (16-bit mono) | |
25 # AL_FORMAT_STEREO16 (16-bit stereo) | |
26 # AL_FORMAT_QUAD16 (16-bit 4-channel) | |
27 # AL_FORMAT_51CHN16 (16-bit 5.1 output) | |
28 # AL_FORMAT_61CHN16 (16-bit 6.1 output) | |
29 # AL_FORMAT_71CHN16 (16-bit 7.1 output) | |
30 # AL_FORMAT_MONO32 (32-bit float mono) | |
31 # AL_FORMAT_STEREO32 (32-bit float stereo) | |

38 ## hrtf: | |
39 # Enables HRTF filters. These filters provide for better sound spatialization | |
40 # while using headphones. The filters will only work when output is 44100hz | |
41 # stereo. While HRTF is active, the cf_level option is disabled. Default is | |
42 # disabled since stereo speaker output quality may suffer. | |
43 #hrtf = false | |
44 | |
45 ## cf_level: | |
46 # Sets the crossfeed level for stereo output. Valid values are: | |
47 # 0 - No crossfeed | |
48 # 1 - Low crossfeed | |
49 # 2 - Middle crossfeed | |
50 # 3 - High crossfeed (virtual speakers are closer to itself) | |
51 # 4 - Low easy crossfeed | |
52 # 5 - Middle easy crossfeed | |
53 # 6 - High easy crossfeed | |
54 # Users of headphones may want to try various settings. Has no effect on non- | |
55 # stereo modes. | |
56 #cf_level = 0 | |
57 | |
58 ## frequency: | |
59 # Sets the output frequency. | |
60 #frequency = 44100 | |
61 | |
62 ## resampler: | |
63 # Selects the resampler used when mixing sources. Valid values are: | |
64 # 0 - None (nearest sample, no interpolation) | |
65 # 1 - Linear (extrapolates samples using a linear slope between samples) | |
66 # 2 - Cubic (extrapolates samples using a Catmull-Rom spline) | |
67 # Specifying other values will result in using the default (linear). | |
68 #resampler = 1 | |
69 | |
70 ## rt-prio: | |
71 # Sets real-time priority for the mixing thread. Not all drivers may use this | |
72 # (eg. PortAudio) as they already control the priority of the mixing thread. | |
73 # 0 and negative values will disable it. Note that this may constitute a | |
74 # security risk since a real-time priority thread can indefinitely block | |
75 # normal-priority threads if it fails to wait. As such, the default is | |
76 # disabled. | |
77 #rt-prio = 0 | |
78 | |
79 ## period_size: | |
80 # Sets the update period size, in frames. This is the number of frames needed | |
81 # for each mixing update. | |
82 #period_size = 1024 | |
83 | |
84 ## periods: | |
85 # Sets the number of update periods. Higher values create a larger mix ahead, | |
86 # which helps protect against skips when the CPU is under load, but increases | |
87 # the delay between a sound getting mixed and being heard. | |
88 #periods = 4 | |
89 | |
90 ## sources: | |
91 # Sets the maximum number of allocatable sources. Lower values may help for | |
92 # systems with apps that try to play more sounds than the CPU can handle. | |
93 #sources = 256 | |
94 | |
95 ## stereodup: | |
96 # Sets whether to duplicate stereo sounds behind the listener for 4+ channel | |
97 # output. This provides a "fuller" playback quality for surround sound output | |
98 # modes, although each individual speaker will have a slight reduction in | |
99 # volume to compensate for the extra output speakers. True, yes, on, and non-0 | |
100 # values will duplicate stereo sources. 0 and anything else will cause stereo | |
101 # sounds to only play in front. This only has an effect when a suitable output | |
102 # format is used (ie. those that contain side and/or rear speakers). | |
103 #stereodup = true | |
104 | |
105 ## drivers: | |
106 # Sets the backend driver list order, comma-seperated. Unknown backends and | |
107 # duplicated names are ignored. Unlisted backends won't be considered for use | |
108 # unless the list is ended with a comma (eg. 'oss,' will list OSS first | |
109 # followed by all other available backends, while 'oss' will list OSS only). | |
110 # Backends prepended with - won't be available for use (eg. '-oss,' will allow | |
111 # all available backends except OSS). An empty list means the default. | |

114 ## excludefx: | |
115 # Sets which effects to exclude, preventing apps from using them. This can | |
116 # help for apps that try to use effects which are too CPU intensive for the | |
117 # system to handle. Available effects are: eaxreverb,reverb,echo,modulator, | |
118 # dedicated | |
119 #excludefx = | |
120 | |
121 ## slots: | |
122 # Sets the maximum number of Auxiliary Effect Slots an app can create. A slot | |
123 # can use a non-negligible amount of CPU time if an effect is set on it even | |
124 # if no sources are feeding it, so this may help when apps use more than the | |
125 # system can handle. | |
126 #slots = 4 | |
127 | |
128 ## sends: | |
129 # Sets the number of auxiliary sends per source. When not specified (default), | |

131 # possible is 4. | |

134 ## layout: | |
135 # Sets the virtual speaker layout. Values are specified in degrees, where 0 is | |
136 # straight in front, negative goes left, and positive goes right. Unspecified | |
137 # speakers will remain at their default positions (which are dependant on the | |
138 # output format). Available speakers are back-left(bl), side-left(sl), front- | |
139 # left(fl), front-center(fc), front-right(fr), side-right(sr), back-right(br), | |
140 # and back-center(bc). | |
