NAME
emu-dspmgr - dsp patch loader and manager for emu10k1 based soundcards
SYNOPSIS
emu-dspmgr
[options]
DESCRIPTION
emu-dspmgr
is used to load/unload dsp patches to/from the emu10k1 processor
present in soundcards such as the Creative Labs SBLive!.
emu-dspmgr
is also used to control the internal routing of signals
(for example digital CD input to rear speakers). Some dsp patches
will have variable settings used to control their functioning
(control gprs)
which can also be modified using
emu-dspmgr.
OPTIONS
-aroute or --add=route
Adds a signal route.
route
is given in the form
input:output
(a list of valid inputs can be obtained with
-i
and outputs with
-o).
-ccontrol or --control=control
Selects
control
gpr to be modified (you also need to set the
-p
option). When used with no arguments prints a list
of the available control gprs.
When this option is used preceding a
-v
(create a route with volume) option, the route's volume control
will use the name specified by the
-c
option.
-Dfile or --=dsp_device=file
Use an alternate device than /dev/dsp.
-d or --debug
Enables debug output. A detailed list of loaded dsp patches will
be printed.
-ffile or --filestart=file
Loads a '.bin' dsp patch from
file.
It must be preceeded by
-l
to indicate the line where to attach the dsp patch.
The patch will have a name specified inside the .bin file, you can rename it to
something else by using the
-p
option.
this will add the patch before any other already loaded patches in the
signal chain.
-Ffile or --fileend=file
Same as
-f
but adds the file to the end of a signal chain
-i or --inputs
List the available inputs.
-lline or --line=line
Selects the
line
where to attach the dsp patch.
line
is one of the valid inputs or outputs.
-melement or --=mixer=element
Map a control GPR to an OSS mixer element. If no element is specified,
a full listing is provided. The option must be preceeded with a patch (-p) and
control GPR (-c)
-Mfile or --=mixer_device=file
Use an alternate mixer than /dev/mixer.
-o or --outputs
List the available output.
-ppatch or --patch=patch
When used with the
-s
(set control GPR), or
-m
(map GPR to OSS mixer control)
options, this
selects the dsp
patch
to be modified.
When used with the
-f
(load patch) option, renames the loaded patch to
-rroute or --remove=route
Removes a signal route.
route
is given in the form
input:output
(a list of valid inputs can be obtained with
-i
and outputs with
-o).
This option
when used with no arguments prints a list of current
signal routes.
(note, if the route is the only route tied to
an input/output line and that line has a patch attached, remove the
patch first, see -z for a quick way to remove everything).
-svalue or --set=value
Sets the
value
of a control gpr. This option must be preceeded by
the
-c
and
-p
options
(with a valid patch and control gpr names)
to select the control gpr to be modified.
value
is a signed 32 bit quantity in hexadecimal.
-uprog or --unload=prog
Unloads a dsp patch. This option when used without arguments
lists all the loaded patches.
-vroute or --volume=route
Adds a signal route with volume control.
route
is given in the form
input:output
(a list of valid inputs can be obtained with
-i
and outputs with
-o).
The option also acts as the
-p
and
-c
options at the same time, so, for example, one can create a route with
volume and map it to an OSS mixer control in a single command.
-z or --clear
removes all routes and unloads all dsp microcode programs
EXAMPLES
Adding a signal route connecting "Pcm L" to "Rear L":
emu-dspmgr -aPcm L:Rear L
Loading the patch effect.bin and placing it in the "Pcm L" line:
emu-dspmgr -lPcm L -feffect.bin
Create a route with volume control a make it controlable by the OSS'
pcm mixer control:
emu-dspmgr -vPcm L:Rear L -mpcm_l
Changing a control gpr value of the "Routing" patch:
emu-dspmgr -pRouting -cVol Pcm L:Rear L -sffffff
Load the tone control patch, rename them as "bass-treble"
and map the bass and treble control gprs to mixer elements in one
command:
emu-dspmgr -pbass-treble -lPcm L -ftone.bin -cbass -mbass -ctreble -mtreble
For an example of a working script, see emu-script distributed with
the driver source in utils/mixer.
BUGS
Not really a bug, but: location matters. Information to be used by
'actions' (-a, -f, m, -r, -s, and -u) should appear before these
actions on the command line, follow order in the examples above.
"Help, route XYZ is unremovable!" --> make sure no patches are tied
to either the input or output of the route and this route is the
only route attached to that input or output.
"Help, the digital out on my SBLive 5.1 doesn't work" --> use
"emu-config -d" to toggle it into digital mode (not a bug).
