# 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). These are the current available settings:
format = AL_FORMAT_STEREO16 # 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)
# Default is AL_FORMAT_STEREO16
cf_level = 0 # 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
# Default is 0. Users of headphones may want to try various
# settings. Has no effect on non-stereo modes.
frequency = 44100 # Sets the output frequency. Default is 44100
refresh = 4096 # Sets the buffer size, in frames. Default is 4096. Note that
# the actual granularity may or may not be less than this.
sources = 256 # 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. Default is 256
stereodup = # Sets whether to duplicate stereo sounds on the rear 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.
# Default is false
drivers = # Sets the backend driver list order, comma-seperated. Unknown
# backends and duplicated names are ignored, and unlisted backends
# won't be considered for use. An empty list means the default.
# Default is:
# alsa,oss,solaris,dsound,winmm,sdl,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:
# reverb
# Default is empty (all available effects enabled)
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. The values must define a
circular pattern, starting with the back-left at the most
negative, around the front to back-center. Unspecified
speakers will remain at their default position. Available
speakers are front-left(fl) and front-right(fr).
The default is:
fl=-90, fr=90
layout_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).
The default is:
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).
The default is:
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).
The default is:
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).
The default is:
bl=-150, sl=-90, fl=-30, fc=0, fr=30, sr=90 br=150
[alsa] # ALSA backend stuff
device = default # Sets the device name for the default playback device.
# Default is default
periods = 0 # Sets the number of update buffers for playback. A value of 0
# means auto-select. Default is 0
capture = default # Sets the device name for the default capture device.
# Default is default
mmap = true # 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.
# Default is true.
[oss] # OSS backend stuff
device = /dev/dsp # Sets the device name for OSS output. Default is /dev/dsp
periods = 4 # Sets the number of update buffers. Default is 4
capture = /dev/dsp # Sets the device name for OSS capture. Default is /dev/dsp
[solaris] # Solaris backend stuff
device = /dev/audio # Sets the device name for Solaris output. Default is
# /dev/audio
[dsound] # DirectSound backend stuff
periods = 4 # Sets the number of updates for the output buffer. Default is 4
[winmm] # Windows Multimedia backend stuff
# Nothing yet...
[port] # PortAudio backend stuff
device = -1 # Sets the device index for output. Negative values will use the
# default as given by PortAudio itself. Default is -1
periods = 4 # Sets the number of update buffers. Default is 4
[sdl] # SDL backend stuff
# Nothing yet...
[wave] # 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.
# THIS WILL OVERWRITE EXISTING FILES WITHOUT QUESTION!
# Default is empty
