Subversion Repositories configs

# 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

#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_STEREO:

#  Sets the speaker layout when using stereo output. 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 position. Available

#  speakers are front-left(fl) and front-right(fr).

#layout_STEREO = fl=-90, fr=90

## laytout_QUAD:

#  Sets the speaker layout when using quadriphonic output. Available speakers

#  are back-left(bl), front-left(fl), front-right(fr), and back-right(br).

#layout_QUAD = bl=-135, fl=-45, fr=45, br=135

## layout_51CHN:

#  Sets the speaker layout when using 5.1 output. Available speakers are back-

#  left(bl), front-left(fl), front-center(fc), front-right(fr), and back-

#  right(br).

#layout_51CHN = bl=-110, fl=-30, fc=0, fr=30, br=110

## layout_61CHN:

#  Sets the speaker layout when using 6.1 output. Available speakers are side-

#  left(sl), front-left(fl), front-center(fc), front-right(fr), side-right(sr),

#  and back-center(bc).

#layout_61CHN = sl=-90, fl=-30, fc=0, fr=30, sr=90, bc=180

## layout_71CHN:

#  Sets the speaker layout when using 7.1 output. Available speakers are back-

#  left(bl), side-left(sl), front-left(fl), front-center(fc), front-right(fr),

#  side-right(sr), and back-right(br).

#layout_71CHN = bl=-150, sl=-90, fl=-30, fc=0, fr=30, sr=90, br=150

## 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.

[solaris]

## device:

#  Sets the device name for Solaris output.

## DirectSound backend stuff

##

[dsound]

##

## Windows Multimedia backend stuff

## PortAudio backend stuff

##

[port]

## device:

#  Sets the device index for output. Negative values will use the default as

## capture:

#  Sets the device index for capture. Negative values will use the default as

## 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!
