+=== BLCK chunk ===
+
+The BLCK chunk directly follows the AST header. It contains a 32-byte header, followed by the PCM16 sound data.
+Here's a description of it:
+
+{| class="wikitable"
+|-
+! Offset (from beginning of BLCK chunk)
+! Size
+! Description
+|-
+| 0x0000
+| 4
+| "BLCK" (0x424C434B)
+|-
+| 0x0004
+| 4
+| Block size? (typically 0x2760)
+|-
+| 0x0008
+| 24
+| Padding (zero)

+| 0x0020

+WARNING: The PCM16 data is stored in BIG-ENDIAN! Don't forget to byteswap each sample you read or your sound will be pure junk!
