The Resource Interchange File Format (RIFF) is the chunked container format which forms the basis for the Microsoft Wave and AVI formats.

Structure

General structure for all RIFF nodes:

Nodes can be data or LIST, data structure is:

4 bytes name (a.k.a. FourCC)
4 bytes length, 32 bit integer in little-endian
length bytes data
optionally 1 byte padding if length is odd

LIST structure is:

4 bytes string "LIST"
4 bytes length, 32 bit integer in little-endian
4 bytes name
length bytes data - data is a list of nodes.
optionally 1 byte padding if length is odd

An entire RIFF file has the structure:

4 bytes string "RIFF"
4 bytes length, 32 bit integer in little-endian
4 bytes name
length bytes data - data is a list of nodes.
