NW > Sound File Overview

This page describes some general data structures seen in a BFSAR file and its subfiles. Each sound file is divided into one or more blocks, which are all aligned to 32 bytes.

File Header

The header is padded with null bytes until it contains a multiple of 32 bytes.

Block Reference

Blocks are looked up by id, so their order doesn't matter.

Section Reference

If a section is not present, the type id is set to 0 and the offset is set to -1.

Item ID

Files are often referenced by 'item id'. An item id consists of both file type and file index. The file index is an index into the reference table of the corresponding file type in the INFO block of the BFSAR file.

Wave ID Table

This table contains references to individual wave files.
