-With '[size]' being the size you're wanting. (TODO: List possible sizes)
+Here, `[size]` is the length of one frame of audio, which varies by the sample rate you use. Here is a list of the possible sample rates and their corresponding frame sizes:
+```
+5734: 0x60
+7884: 0x84 (This mode is not aligned to the buffer length and is not supported by the mixer)
+10512: 0xB0
+13379: 0xE0 (This is the default engine rate; without any modifications, this is what the GBA Pokemon games use)
