								# 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 "$$".

								#

								# Device-specific values may be specified by including the device name in the

								# block name, with "general" replaced by the device name. That is, general

								# options for the device "Name of Device" would be in the [Name of Device]

								# block, while ALSA options would be in the [alsa/Name of Device] block.

								# Options marked as "(global)" are not influenced by the device.

								#

								# 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-senstive. 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]


								## disable-cpu-exts: (global)

								#  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, sse3, sse4.1, and neon.

								#  Specifying 'all' disables use of all such specialized methods.

								#disable-cpu-exts =


								## drivers: (global)

								#  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,

								#  ambi1, ambi2, ambi3. Note that the ambi* configurations provide ambisonic

								#  channels of the given order (using ACN ordering and SN3D normalization by

								#  default), which need to be decoded to play correctly on speakers.

								#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

								## period_size:

								#  Sets the update period size, in sample frames. This is the number of frames

								#  for 44100, 960 for 48000, etc).

								#period_size =


								## periods:

								#  Sets the number of update periods. Higher values create a larger mix ahead,

								#  Valid settings are auto, speakers, and headphones.

								#stereo-mode = auto


								## stereo-encoding:

								#  Specifies the encoding method for non-HRTF stereo output. 'panpot' (default)

								#  uses standard amplitude panning (aka pair-wise, stereo pair, etc) between

								#  -30 and +30 degrees, while 'uhj' creates stereo-compatible two-channel UHJ

								#  output, which encodes some surround sound information into stereo output

								#  that can be decoded with a surround sound receiver. If crossfeed filters are

								#  used, UHJ is disabled.

								#  Specifies the channel order and normalization for the "ambi*" set of channel

								#  configurations. Valid settings are: fuma, ambix (or acn+sn3d), acn+n3d

								#ambi-format = ambix


								## hrtf:

								#  Controls HRTF processing. These filters provide better spatialization of

								#  sounds while using headphones, but do require a bit more CPU power. The

								#  default filters will only work with 44100hz or 48000hz stereo output. While

								#  HRTF is used, the cf_level option is ignored. Setting this to auto (default)

								#  will allow HRTF to be used when headphones are detected or the app requests

								#  it, while setting true or false will forcefully enable or disable HRTF

								#  respectively.

								#hrtf = auto


								## default-hrtf:

								#  Specifies the default HRTF to use. When multiple HRTFs are available, this

								#  determines the preferred one to use if none are specifically requested. Note

								#  that this is the enumerated HRTF name, not necessarily the filename.

								#default-hrtf =


								## hrtf-paths:

								#  Specifies a comma-separated list of paths containing HRTF data sets. The

								#  format of the files are described in docs/hrtf.txt. The files within the

								#  directories must have the .mhr file extension to be recognized. By default,

								#  OS-dependent data paths will be used. They will also be used if the list

								#  ends with a comma. On Windows this is:

								#  $AppData\openal\hrtf

								#  And on other systems, it's (in order):

								#  3 - High crossfeed (virtual speakers are closer to itself)

								#  4 - Low easy crossfeed

								#  Users of headphones may want to try various settings. Has no effect on non-

								#  stereo modes.

								## resampler: (global)

								#  Selects the resampler used when mixing sources. Valid values are:

								#  cubic - extrapolates samples using a Catmull-Rom spline

								#  bsinc12 - extrapolates samples using a band-limited Sinc filter (varying

								#            between 12 and 24 points, with anti-aliasing)

								## rt-prio: (global)

								#  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.

								## front-stablizer:

								#  Applies filters to "stablize" front sound imaging. A psychoacoustic method

								#  is used to generate a front-center channel signal from the front-left and

								#  front-right channels, improving the front response by reducing the combing

								#  artifacts and phase errors. Consequently, it will only work with channel

								#  configurations that include front-left, front-right, and front-center.

								## dither:

								#  Applies dithering on the final mix, for 8- and 16-bit output by default.

								#  This replaces the distortion created by nearest-value quantization with low-

								#  level whitenoise.

								#dither = true


								## dither-depth:

								#  Quantization bit-depth for dithered output. A value of 0 (or less) will

								#  match the output sample depth. For int32, uint32, and float32 output, 0 will

								#  disable dithering because they're at or beyond the rendered precision. The

								#  maximum dither depth is 24.

								#dither-depth = 0


								## volume-adjust:

								#  A global volume adjustment for source 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 x1/2, and -12 is about x1/4. A

								#  value of 0 means no change.

								#volume-adjust = 0


								## excludefx: (global)

								#  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,pshifter,

								#  fshifter

								#excludefx =


								## default-reverb: (global)

								#  A reverb preset that applies by default to all sources on send 0

								#  Available presets are: None, Generic, PaddedCell, Room, Bathroom,

								#  Livingroom, Stoneroom, Auditorium, ConcertHall, Cave, Arena, Hangar,

								## trap-alc-error: (global)

								#  Generates a SIGTRAP signal when an ALC device error is generated, on systems

								#trap-alc-error = false


								## trap-al-error: (global)

								## Ambisonic decoder stuff

								## hq-mode:

								#  Enables a high-quality ambisonic decoder. This mode is capable of frequency-

								#  dependent processing, creating a better reproduction of 3D sound rendering

								#  over surround sound speakers. Enabling this also requires specifying decoder

								#  configuration files for the appropriate speaker configuration you intend to

								#  use (see the quad, surround51, etc options below). Currently, up to third-

								#  order decoding is supported.

								hq-mode = false


								## distance-comp:

								#  Enables compensation for the speakers' relative distances to the listener.

								#  This applies the necessary delays and attenuation to make the speakers

								#  playback of 3D sound rendering. Requires the proper distances to be

								#  specified in the decoder configuration file.

								distance-comp = true


								## nfc:

								#  Enables near-field control filters. This simulates and compensates for low-

								#  frequency effects caused by the curvature of nearby sound-waves, which

								#  creates a more realistic perception of sound distance. Note that the effect

								#  may be stronger or weaker than intended if the application doesn't use or

								#  specify an appropriate unit scale, or if incorrect speaker distances are set

								#  in the decoder configuration file.

								nfc = false


								## nfc-ref-delay

								#  Specifies the reference delay value for ambisonic output when NFC filters

								#  are enabled. If channels is set to one of the ambi* formats, this option

								#  enables NFC-HOA output with the specified Reference Delay parameter. The

								#  specified value can then be shared with an appropriate NFC-HOA decoder to

								#  reproduce correct near-field effects. Keep in mind that despite being

								#  designed for higher-order ambisonics, this also applies to first-order

								#  output. When left unset, normal output is created with no near-field

								#  simulation. Requires the nfc option to also be enabled.
