RIFF to CAL Conversion: FAQ

What are RIFF files?

The Resource Interchange File Format RIFF is a structured multimedia container format developed through a collaboration between Microsoft and IBM in 1991. As an adaptation of the Electronic Arts Interchange File Format (IFF), RIFF implements a tagged chunk architecture where each data segment contains a 4-character identifier, 32-bit size field, and payload data. This design enables hierarchical organization of heterogeneous multimedia streams while maintaining platform-independent data representation through strict little-endian byte ordering.
