Chris Robinson 2a62b38530 Update filter histories even when they're not used
If the filter properties are continually updated, and the HF or LF gain goes
from <1, to 1, and later back to <1, the history shouldn't hold stale values
from before it was at 1.

Source Install
==============

To install OpenAL Soft, use your favorite shell to go into the build/
directory, and run:

cmake ..

Assuming configuration went well, you can then build it, typically using GNU
Make (KDevelop, MSVC, and others are possible depending on your system setup
and CMake configuration).

Please Note: Double check that the appropriate backends were detected. Often,
complaints of no sound, crashing, and missing devices can be solved by making
sure the correct backends are being used. CMake's output will identify which
backends were enabled.

For most systems, you will likely want to make sure ALSA, OSS, and PulseAudio
were detected (if your target system uses them). For Windows, make sure
DirectSound was detected.


Utilities
=========

The source package comes with an informational utility, openal-info, and is
built by default. It prints out information provided by the ALC and AL sub-
systems, including discovered devices, version information, and extensions.


Configuration
=============

OpenAL Soft can be configured on a per-user and per-system basis. This allows
users and sysadmins to control information provided to applications, as well
as application-agnostic behavior of the library. See alsoftrc.sample for
available settings.


Acknowledgements
================

Special thanks go to:

Creative Labs for the original source code this is based off of.

Christopher Fitzgerald for the current reverb effect implementation, and
helping with the low-pass and HRTF filters.

Christian Borss for the 3D panning code previous versions used as a base.

Ben Davis for the idea behind a previous version of the click-removal code.

Richard Furse for helping with my understanding of Ambisonics that is used by
the various parts of the library.
