+ <p>Welcome to the exciting world of OpenAL! OpenAL
+is still in a stage of growth, and even though there is an ever larger following
+to the API it still hasn't reached it's full potential. One of the big reasons
+for this is that there is still not yet hardware acceleration built in for
+specific cards. However, Creative Labs is a major contributor to the OpenAL
+project and also happens to be one of the largest soundcard manufacturers. So
+there is a promise of hardware accelerated features in the near future. OpenAL's
+only other major contributor, Loki, has gone the way of the dinosaur. So the
+future of OpenAL on Linux platforms is uncertain. You can still obtain the Linux
+binaries on some more obscure websites.</p>
+<p>OpenAL has also not been seen in many major
+commercial products, which may have also hurt it's growth. As far as I know the
+only pc game to use OpenAL has been Metal Gear 2 (although recently I've
+discovered that Unreal 2 does as well). The popular modeling program, Blender3D,
+was also known to use OpenAL for all it's audio playback. Aside from these
+however the only other OpenAL uses have been in the sdk examples and a few
+obscure tutorials on the internet.</p>
+<p>But lets face it, OpenAL has a lot of
+potential. There are many other audio libraries that claim to work with the
+hardware on a lower level (and this may be true), but the designers of OpenAL
+did several things in it's design which make it a superior API. First of all
+they emulated the OpenGL API which is one of the best ever designed. The API
+style is flexible, so different coding methods and hardware implementations will
+take advantage of this. People who have had a lot of experience with OpenGL will
+be able to pick up OpenAL quite fast. OpenAL also has the advantage of creating
+3D surround sound which a lot of other API's cannot boast. On top of all of that
+it also has the ability to extend itself into EAX and AC3 flawlessly. To my
+knowledge no other audio library has that capability.</p>
+<p>If you still haven't found a reason here to use
+OpenAL then here's another. It's just cool. It's a nice looking API and will
+integrate well into your code. You will be able to do many cool sound effects
+with it. But before we do that we have to learn the basics.</p>
+
+<p>So let's get coding!</p>

+</pre>
+<p>Those familiar with OpenGL know that it uses &quot;texture objects&quot; (or &quot;texture
+names&quot;) to handle textures used by a program. OpenAL does a similar thing with
+audio samples. There are essentially 3 kinds of objects in OpenAL. A buffer
+which stores all the information about how a sound should be played and the
+sound data itself, and a source which is a point in space that emits a sound.
+It's important to understand that a source is not itself an audio sample. A
+source only plays back sound data from a buffer bound to it. The source is also
+given special properties like position and velocity. </p>
+<p>The third object which I have not mentioned yet is the listener. There is
+only one listener which represents where 'you' are, the user. The listener
+properties along with the source properties determine how the audio sample will
+be heard. For example their relative positions will determine the intensity of
+the sound.</p>

+<p>The function 'alGenBuffers' will create the buffer objects and store them in
+the variable we passed it. It's important to do an error check to make sure
+everything went smoothly. There may be a case in which OpenAL could not generate
+a buffer object due to a lack of memory. In this case it would set the error
+bit.</p>
+<p>The ALut is very helpful here. It opens up the file for us and gives us all
+ the information we need to create the buffer. And after we have attached all
+ this data to the buffer it will help use dispose of the data. It all works in
+ a clean and efficient manner.</p>

+<p>We generate a source object in the same manner we generated the buffer object.
+Then we define the source properties that it will use when it's in playback. The
+most important of these properties is the buffer it should use. This tells the
+source which audio sample to playback. In this case we only have one so we bind
+it. We also tell the source it's position and velocity which we defined earlier.</p>
+<p>One more thing on 'alGenBuffers' and 'alGenSources'. In some example code I
+have seen these functions will return an integer value for the number of
+buffers/sources created. I suppose this was meant as an error checking feature
+that was left out in a later version. If you see this done in other code don't
+use it yourself. If you want to do this check, use 'alGetError' instead (like we
+have done above).</p>

+<p>This is the interesting part of the tutorial. It's a very basic loop that
+lets us control the playback of the audio sample. Pressing 'p' will replay the
+sample, pressing 's' will stop the sample, and pressing 'h' will pause the
+sample. Pressing 'q' will exit the program.</p>
+<p>Well there it is. Your first delve into OpenAL. I hope it was made simple
+enough for you. It may have been a little too simple for the 1337 h4X0r, but we
+all got to start somewhere. Things will get more advanced as we go along.</p>
