# 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 ## 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 ## 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 ## 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 - Cubic (extrapolates samples using a Catmull-Rom spline) # 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. 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 ## period_size: # Sets the update period size, in frames. This is the number of frames needed # for each mixing update. #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 behind the listener for 4+ channel # output. This provides a "fuller" playback quality for surround sound output # modes, although each individual speaker will have a slight reduction in # volume to compensate for the extra output speakers. True, yes, on, and non-0 # values will duplicate stereo sources. 0 and anything else will cause stereo # sounds to only play in front. This only has an effect when a suitable output # format is used (ie. those that contain side and/or rear speakers). #stereodup = true ## 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). # Backends prepended with - won't be available for use (eg. '-oss,' will allow # all available backends except OSS). An empty list means the default. #drivers = pulse,alsa,core,oss,solaris,sndio,mmdevapi,dsound,winmm,port,opensl,null,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, # dedicated #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 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 = ## 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 = ## layout_*: # Channel-specific layouts may be specified to override the layout option. The # same speakers as the layout option are available, and the default settings # are shown below. #layout_STEREO = fl=-90, fr=90 #layout_QUAD = fl=-45, fr=45, bl=-135, br=135 #layout_51CHN = fl=-30, fr=30, fc=0, bl=-110, br=110 #layout_61CHN = fl=-30, fr=30, fc=0, sl=-90, sr=90, bc=180 #layout_71CHN = fl=-30, fr=30, fc=0, sl=-90, sr=90, bl=-150, br=150 ## 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. # Optionally, the __ALSOFT_TRAP_ALC_ERROR env var may be set before running # the app instead. #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. # Optionally, the __ALSOFT_TRAP_AL_ERROR env var may be set before running the # app instead. #trap-al-error = false ## ## 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 ## ## ALSA backend stuff ## [alsa] ## device: # Sets the device name for the default playback device. #device = default ## device-prefix: # Sets the prefix used by the discovered (non-default) playback devices. This # will be appended with "CARD=c,DEV=d", where c is the card id and d is the # device index for the requested device name. #device-prefix = plughw: ## capture: # Sets the device name for the default capture device. #capture = default ## capture-prefix: # Sets the prefix used by the discovered (non-default) capture devices. This # will be appended with "CARD=c,DEV=d", where c is the card number and d is # the device number for the requested device name. #capture-prefix = plughw: ## 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 ## ## MMDevApi backend stuff ## [mmdevapi] ## ## 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 ## ## 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 =
