# OpenAL config file. Options that are not under a block or are under the # [general] block are for general, non-backend-specific options. Blocks may # appear multiple times, and duplicated options will take the last value # specified. # The system-wide settings can be put in /etc/openal/alsoft.conf and user- # specific override settings in ~/.alsoftrc. # For Windows, these settings should go into %AppData%\alsoft.ini # The environment variable ALSOFT_CONF can be used to specify another config # override # Option and block names are case-insenstive. The supplied values are only # hints and may not be honored (though generally it'll try to get as close as # possible). Note: options that are left unset may default to app- or system- # specified values. These are the current available settings: ## format: # Sets the output format. Can be one of: # AL_FORMAT_MONO8 (8-bit mono) # AL_FORMAT_STEREO8 (8-bit stereo) # AL_FORMAT_QUAD8 (8-bit 4-channel) # AL_FORMAT_51CHN8 (8-bit 5.1 output) # AL_FORMAT_61CHN8 (8-bit 6.1 output) # AL_FORMAT_71CHN8 (8-bit 7.1 output) # AL_FORMAT_MONO16 (16-bit mono) # AL_FORMAT_STEREO16 (16-bit stereo) # AL_FORMAT_QUAD16 (16-bit 4-channel) # AL_FORMAT_51CHN16 (16-bit 5.1 output) # AL_FORMAT_61CHN16 (16-bit 6.1 output) # AL_FORMAT_71CHN16 (16-bit 7.1 output) # AL_FORMAT_MONO32 (32-bit float mono) # AL_FORMAT_STEREO32 (32-bit float stereo) # AL_FORMAT_QUAD32 (32-bit float 4-channel) # AL_FORMAT_51CHN32 (32-bit float 5.1 output) # AL_FORMAT_61CHN32 (32-bit float 6.1 output) # AL_FORMAT_71CHN32 (32-bit float 7.1 output) #format = AL_FORMAT_STEREO16 ## cf_level: # Sets the crossfeed level for stereo output. Valid values are: # 0 - No crossfeed # 1 - Low crossfeed # 2 - Middle crossfeed # 3 - High crossfeed (virtual speakers are closer to itself) # 4 - Low easy crossfeed # 5 - Middle easy crossfeed # 6 - High easy crossfeed # Users of headphones may want to try various settings. Has no effect on non- # stereo modes. #cf_level = 0 ## head_dampen: # Sets the amount of dampening on sounds emanating from behind the listener. # This is used to simulate the natural occlusion of the head, which is # typically missing with mono and stereo output, and as such, only works on # mono and stereo output modes. Valid values range from 0 to 1 (inclusive), # and higher values provide a stronger effect. #head_dampen = 0.25 ## frequency: # Sets the output frequency. #frequency = 44100 ## resampler: # Selects the resampler used when mixing sources. Valid values are: # 0 - None (nearest sample, no interpolation) # 1 - Linear (extrapolates samples using a linear slope between samples) # 2 - Cosine (extrapolates using a (co)sine slope) # Specifying other values will result in using the default (linear). #resampler = 1 ## rt-prio: # Sets real-time priority for the mixing thread. Not all drivers may use this # (eg. PulseAudio) as they already control the priority of the mixing thread. # 0 and negative values will disable it. Note that this may constitute a # security risk since a real-time priority thread can indefinitely block # normal-priority threads if it fails to wait. As such, the default is # disabled. #rt-prio = 0 ## period_size: # Sets the update period size, in frames. This is the number of frames needed # for each mixing update. If the deprecated 'refresh' option is specified and # this isn't, the value will be calculated as size = refresh/periods. #period_size = 1024 ## periods: # Sets the number of update periods. Higher values create a larger mix ahead, # which helps protect against skips when the CPU is under load, but increases # the delay between a sound getting mixed and being heard. #periods = 4 ## sources: # Sets the maximum number of allocatable sources. Lower values may help for # systems with apps that try to play more sounds than the CPU can handle. #sources = 256 ## stereodup: # Sets whether to duplicate stereo sounds on the rear and side speakers for 4+ # channel output. This can make stereo sources substantially louder than mono # or even 4+ channel sources, but provides a "fuller" playback quality. True, # yes, on, and non-0 values will duplicate stereo sources. 0 and anything else # will cause stereo sounds to only play out the front speakers. #stereodup = false ## drivers: # Sets the backend driver list order, comma-seperated. Unknown backends and # duplicated names are ignored. Unlisted backends won't be considered for use # unless the list is ended with a comma (eg. 'oss,' will list OSS first # followed by all other available backends, while 'oss' will list OSS only). # An empty list means the default. #drivers = pulse,alsa,oss,solaris,dsound,winmm,port,wave ## excludefx: # Sets which effects to exclude, preventing apps from using them. This can # help for apps that try to use effects which are too CPU intensive for the # system to handle. Available effects are: eaxreverb,reverb,echo,modulator #excludefx = ## slots: # Sets the maximum number of Auxiliary Effect Slots an app can create. A slot # can use a non-negligible amount of CPU time if an effect is set on it even # if no sources are feeding it, so this may help when apps use more than the # system can handle. #slots = 4 ## sends: # Sets the maximum number of auxiliary sends per source. The total number of # sends possible is defined at compile time and thus can not be increased # beyond the default (2). #sends = 2 ## layout: # Sets the virtual speaker layout. Values are specified in degrees, where 0 is # straight in front, negative goes left, and positive goes right. Unspecified # speakers will remain at their default positions (which are dependant on the # output format). Available speakers are back-left(bl), side-left(sl), front- # left(fl), front-center(fc), front-right(fr), side-right(sr), back-right(br), # and back-center(bc). #layout = ## ## ALSA backend stuff ## [alsa] ## device: # Sets the device name for the default playback device. #device = default ## capture: # Sets the device name for the default capture device. #capture = default ## mmap: # Sets whether to try using mmap mode (helps reduce latencies and CPU # consumption). If mmap isn't available, it will automatically fall back to # non-mmap mode. True, yes, on, and non-0 values will attempt to use mmap. 0 # and anything else will force mmap off. #mmap = true ## ## OSS backend stuff ## [oss] ## device: # Sets the device name for OSS output. #device = /dev/dsp ## capture: # Sets the device name for OSS capture. #capture = /dev/dsp ## ## Solaris backend stuff ## [solaris] ## device: # Sets the device name for Solaris output. #device = /dev/audio ## ## DirectSound backend stuff ## [dsound] ## ## Windows Multimedia backend stuff ## [winmm] ## ## PortAudio backend stuff ## [port] ## device: # Sets the device index for output. Negative values will use the default as # given by PortAudio itself. #device = -1 ## capture: # Sets the device index for capture. Negative values will use the default as # given by PortAudio itself. #capture = -1 ## ## PulseAudio backend stuff ## [pulse] ## spawn-server: # Attempts to spawn a PulseAudio server when requesting to open a PulseAudio # device. Note that some apps may open and probe all enumerated devices on # startup, causing a server to spawn even if a PulseAudio device is not # actually selected. Setting autospawn to false in Pulse's client.conf will # still prevent autospawning even if this is set to true. #spawn-server = false ## buffer-length: # Specifies the PulseAudio buffer length, in sample frames. When set to a # non-0 value, it specifies the total buffer length for the playback stream, # overriding the period settings. Otherwise it uses the period size and count # to calculate a buffer size. PulseAudio, unlike other backends, does not work # in period chunks, but instead just has one buffer block which is refilled as # it nears empty. Because of this, the usual buffering metrics are unsuitable, # with the default 4096 frames being needlessly large. #buffer-length = 2048 ## ## Wave File Writer stuff ## [wave] ## file: # Sets the filename of the wave file to write to. An empty name prevents the # backend from opening, even when explicitly requested. # THIS WILL OVERWRITE EXISTING FILES WITHOUT QUESTION! #file =
