This directory contains example speaker configuration files.
|
|
To use one simple copy it to $HOME/.openal-speakers
|
|
|
|
The format is simple:
|
|
|
|
<n>: <gain> <x> <y> <z>
|
|
|
|
where <n> is a number indication which speaker:
|
|
|
|
0: front left
|
|
1: front right
|
|
2: rear left
|
|
3: rear right
|
|
4: center
|
|
5: lfe
|
|
6: side left
|
|
7: side right
|
|
|
|
<gain> is a per speaker gain control between 0.0 and 1.0.
|
|
Setting the gain to 0.0 disables output to the speaker.
|
|
|
|
<x> <y> <z> is the speaker position.
|
|
<x> is forward, <y> is up and <z> is to the right.
|
|
Only the direction of this vector is used.
|
|
|
|
Anything after a "#" is considered a comment.
|
|
|
|
speakers-mono:
|
|
|
|
This one is just simple example.
|
|
|
|
speakers-stereo:
|
|
|
|
This is the default configuration. If you are going to use this
|
|
you may as well not bother with a speakers file.
|
|
|
|
speakers-quadraphonic:
|
|
|
|
Fourpoint output. Each speaker placed in different corner of a square.
|
|
|
|
speakers-fivepoint-a:
|
|
|
|
This is what I'm told is the correct placement of speakers in a 5.1
|
|
setup. The front speakers are 30° from the center speaker and the rear
|
|
speakers are 110° from the center speaker. This is very front biased.
|
|
Due to they way I calculate the speaker gain/volume sound behind you ends up
|
|
being very quiet. I know there are schemes I could use that would allow for
|
|
this but they don't seems to cope very well with the lack of above of below
|
|
speakers.
|
|
|
|
speakers-fivepoint-b:
|
|
|
|
This is the five speakers placed evenly around the listener, such
|
|
that they are all 72° from their neighbours.
|
|
|
|
speakers-fivepoint-c:
|
|
|
|
This has the front are rear speakers placed the same as for the
|
|
quadraphonic configuration with the addition of the front speaker.
|
|
|
|
speakers-fivepoint-d:
|
|
|
|
This has the speakers each placed 60° from their neighbours. The
|
|
speakers would be placed evenly around the listener in this configuration
|
|
if there was a single rear speaker.
|
|
|
|
speakers-sevenpoint-a:
|
|
|
|
I have no idea what the correct placement for 7.1 systems is. This
|
|
is with the front three speakers placed the same as the 5.1 setup. The
|
|
side speakers are placed 90° from the front. And the rear are placed at
|
|
60° from their neighbours. The end result is a configuration where
|
|
everything would be placed evenly around the listener if you take away the
|
|
front speaker.
|
|
|
|
speakers-sevenpoint-b:
|
|
|
|
This is the seven speakers placed evenly around the listener.
|
|
This has them all at some funny angle from their neighbours.
|
|
|
|
speakers-sevenpoint-c:
|
|
|
|
This has the front and rear speakers placed the same as for the
|
|
quadraphonic configuration. And the side speakers are placed 90° from the
|
|
front. The speakers would be placed evenly around the listener in this
|
|
configuration with the addition of a rear center speaker.
