What is this?

This is my version of OpenAL. It is a modified version of the Linux reference version by Loki Software. The differences included numerous bug fixes, working fourpoint output and working listener orientation.

I've merged the changes to Loki's version. This is not as well tested as I'd like.

I think I was doing the fourpoint panning wrong. I was multiplying the front/back with the left/right. I did this because the result was applied by multiplying the gain with it. So in effect I was applying one then applying the other. But looking at the numbers that gave incorrect results. So I'm now taking and average of the two components and applying that.

Well, with no one giving me any feedback what do you expect?

With the new Sound Blaster Live driver that has gone into version 2.4.8 of the Linux kernel you can now get fourpoint output without splitting between /dev/dsp0 and /dev/dsp1. So I've updated the generic Linux driver in my OpenAL to support this. You can now specify the number of output channels with the following in your .openalrc:

(define speaker-num 4)

I've merged the changes to Loki's version. And added a compile time option to use left handed co-ordinate space.

Changed panning function so that it no longer divides the gain between the channels.

The "pre-1-0" version now has a new compile time option to correct the listener orientation for Soldier of Fortune. This has only been tested with SoF 1.05.

17 July 2001

There are now two version of this. The first being the current version. The "pre-1-0" one is based on an old stable branch and is intended for use with versions 1.04 and 1.05 of Loki's port of Soldier of Fortune.
