* @brief RIFF specific classes and definitions |
87 |
|
* |
88 |
|
* The Resource Interchange File Format (RIFF) is a generic tree-structured |
89 |
|
* meta-format which stores data in so called "chunks". It can be compared |
90 |
|
* to XML, but in contrast to XML, RIFF is entirely binary encoded, that is |
91 |
|
* not ASCII based. RIFF is used as basis for many file formats like AVI, |
92 |
|
* WAV, DLS and of course the Gigasampler file format. ;-) |
93 |
|
* |
94 |
|
* RIFF chunks can be seen as containers for data. There are two distinct |
95 |
|
* types of chunks: |
96 |
|
* |
97 |
|
* - @e ordinary @e chunks are the leafs of the data tree which encapsulate |
98 |
|
* the actual data of the file (i.e. the sample data of a .wav file) |
99 |
|
* |
100 |
|
* - @e list @e chunks are the nodes of the data tree which hold an |
101 |
|
* arbitrary amount of subchunks (can be both, list chunks and/or ordinary |
102 |
|
* chunks) |
