# 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 filters 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

 ## 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

 ## device:

 #  Sets the device name for the default playback device.

 #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.

 ## spawn-server:

 #  Attempts to spawn a PulseAudio server when requesting to open a PulseAudio

 #  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

 ## file:

 #  Sets the filename of the wave file to write to. An empty name prevents the

 #  backend from opening, even when explicitly requested.
