<p>Key ideas:</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>Sound is necessarily temporal. You can drop a frame of video and the user probably won't notice, but if your audio
|
|
|
|
|
drops out, they probably will notice.</li>
|
|
|
|
|
<li>Sound bufers are small, and not all platforms will require us to deal with circular buffers. So one option is to do
|
|
|
|
|
a buffer copy per frame and present the game with a contiguous block of memory. This should be cheap enough.</li>
|
|
|
|
|
<li>Much like the bitmap, allocate plenty of space for a sound buffer at startup, and reuse it each frame.</li>
|
|
|
|
|
</ul>

|
|
|
|
|
<p><code>alloca</code> is a compiler feature that allows for dynamic allocation <em>on the stack</em>. Much was learned and discussed, but
|
|
|
|
|
it should be noted that the function is deprecated and probably shouldn't be used in shipping code.</p>
