# OpenAL config file. # # Option blocks may appear multiple times, and duplicated options will take the # last value specified. Environment variables may be specified within option # values, and are automatically substituted when the config file is loaded. # Environment variable names may only contain alpha-numeric characters (a-z, # A-Z, 0-9) and underscores (_), and are prefixed with $. For example, # specifying "$HOME/file.ext" would typically result in something like # "/home/user/file.ext". To specify an actual "$" character, use "$$". # # The system-wide settings can be put in /etc/openal/alsoft.conf and user- # specific override settings in $HOME/.alsoftrc. # For Windows, these settings should go into $AppData\alsoft.ini # # 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: ## ## General stuff ## [general] ## disable-cpu-exts: # Disables use of specialized methods that use specific CPU intrinsics. # Certain methods may utilize CPU extensions for improved performance, and # this option is useful for preventing some or all of those methods from being # used. The available extensions are: sse, sse2, sse4.1, and neon. Specifying # 'all' disables use of all such specialized methods. #disable-cpu-exts = ## 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 (e.g. 'oss,' will try OSS first before # other backends, while 'oss' will try OSS only). Backends prepended with - # won't be considered for use (e.g. '-oss,' will try all available backends # except OSS). An empty list means to try all backends. #drivers = ## channels: # Sets the output channel configuration. If left unspecified, one will try to # be detected from the system, and defaulting to stereo. The available values # are: mono, stereo, quad, surround51, surround51rear, surround61, surround71 #channels = ## sample-type: # Sets the output sample type. Currently, all mixing is done with 32-bit float # and converted to the output sample type as needed. Available values are: # int8 - signed 8-bit int # uint8 - unsigned 8-bit int # int16 - signed 16-bit int # uint16 - unsigned 16-bit int # int32 - signed 32-bit int # uint32 - unsigned 32-bit int # float32 - 32-bit float #sample-type = float32 ## frequency: # Sets the output frequency. If left unspecified it will try to detect a # default from the system, otherwise it will default to 44100. #frequency = ## period_size: # Sets the update period size, in frames. This is the number of frames needed # for each mixing update. Acceptable values range between 64 and 8192. #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. Acceptable values # range between 2 and 16. #periods = 4 ## stereo-mode # Specifies if stereo output is treated as being headphones or speakers. With # headphones, HRTF or crossfeed filters may be used for better audio quality. #stereo-mode = auto ## hrtf: # Enables HRTF filters. These filters provide for better sound spatialization # while using headphones. The default filter will only work when output is # 44100hz stereo. While HRTF is active, the cf_level option is disabled. # Default is disabled since stereo speaker output quality may suffer. #hrtf = false ## hrtf_tables # Specifies a comma-separated list of files containing HRTF data sets. The # format of the files are described in hrtf.txt. The filenames may contain # these markers, which will be replaced as needed: # %r - Device sampling rate # %% - Percent sign (%) # The listed files are relative to system-dependant data directories. On # Windows this is: # $AppData\openal\hrtf # And on other systems, it's (in order): # $XDG_DATA_HOME/openal/hrtf (defaults to $HOME/.local/share/openal/hrtf) # $XDG_DATA_DIRS/openal/hrtf (defaults to /usr/local/share/openal/hrtf and # /usr/share/openal/hrtf) # An absolute path may also be specified, if the given file is elsewhere. #hrtf_tables = default-%r.mhr ## 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 ## resampler: # Selects the resampler used when mixing sources. Valid values are: # point - nearest sample, no interpolation # linear - extrapolates samples using a linear slope between samples # cubic - extrapolates samples using a Catmull-Rom spline # Specifying other values will result in using the default (linear). #resampler = linear ## rt-prio: # Sets real-time priority for the mixing thread. Not all drivers may use this # (eg. PortAudio) 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 ## 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 ## 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 number of auxiliary sends per source. When not specified (default), # it allows the app to request how many it wants. The maximum value currently # possible is 4. #sends = ## 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,autowah,chorus, # compressor,distortion,echo,equalizer,flanger,modulator,dedicated #excludefx = ## default-reverb: # A reverb preset that applies by default to all sources on send 0 # (applications that set their own slots on send 0 will override this). # Available presets are: None, Generic, PaddedCell, Room, Bathroom, # Livingroom, Stoneroom, Auditorium, ConcertHall, Cave, Arena, Hangar, # CarpetedHallway, Hallway, StoneCorridor, Alley, Forest, City, Moutains, # Quarry, Plain, ParkingLot, SewerPipe, Underwater, Drugged, Dizzy, Psychotic. #default-reverb = ## trap-alc-error: # Generates a SIGTRAP signal when an ALC device error is generated, on systems # that support it. This helps when debugging, while trying to find the cause # of a device error. On Windows, a breakpoint exception is generated. #trap-alc-error = false ## trap-al-error: # Generates a SIGTRAP signal when an AL context error is generated, on systems # that support it. This helps when debugging, while trying to find the cause # of a context error. On Windows, a breakpoint exception is generated. #trap-al-error = false ## ## MIDI stuff (EXPERIMENTAL) ## [midi] ## soundfont: # A default soundfont (sf2 format). Used when an app requests the system # default.

This # is used to help keep the mix from clipping, and so must be 0 or less. The # value is logarithmic, so -6 will be about half amplitude, and -12 about # 1/4th. The default is roughly -13.9794 (0.2, or 1/5th). #volume = ## ## Reverb effect stuff (includes EAX reverb) ## [reverb] ## boost: # A global amplification for reverb output, expressed in decibels. The value # is logarithmic, so +6 will be a scale of (approximately) 2x, +12 will be a # scale of 4x, etc. Similarly, -6 will be about half, and -12 about 1/4th. A # value of 0 means no change. #boost = 0 ## emulate-eax: # Allows the standard reverb effect to be used in place of EAX reverb. EAX # reverb processing is a bit more CPU intensive than standard, so this option # allows a simpler effect to be used at the loss of some quality. #emulate-eax = false ## ## PulseAudio backend stuff ## [pulse] ## spawn-server: # Attempts to autospawn a PulseAudio server whenever needed (initializing the # backend, enumerating devices, etc). Setting autospawn to false in Pulse's # client.conf will still prevent autospawning even if this is set to true. #spawn-server = true ## allow-moves: # Allows PulseAudio to move active streams to different devices.

The option may specify the card id (eg, # capture-prefix-NVidia), or the card id and device index (eg, # capture-prefix-NVidia-0). The card id is case-sensitive. #capture-prefix- = ## 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 ## ## QSA backend stuff ## [qsa] ## ## MMDevApi backend stuff ## [mmdevapi] ## ## DirectSound backend stuff ## [dsound] ## ## Windows Multimedia backend stuff ## [winmm] ## ## PortAudio backend stuff ## [port] ## device: # Sets the device index for output.
