(1) A relatively simple, catchy repeated phrase. May be played behind a soloist or as part of a head. Often in a bluesy style. Riff tunes are made up of riffs, characteristic of the black bands of the 30s. (2) A pre-packaged phrase used by an improviser when he can't think of anything else, especially one which is especially catchy.
A musical phrase, usually repeated for a whole section of a song, which gives the song its flavour and sometimes its hook . Rifts are most frequently played on guitar and/or bass, occasionally on other instruments.
Resource Interchange File Format. A platform-independent multimedia specification (published by Microsoft and others in 1990) that allows audio, image, animation, and other multimedia elements to be stored in a common format.
The Raster Image File Format, desighed by Mark Zimmer of Fractal Software, and used by Letterset. This MacOS format supports Black and White (B&W), Grayscale, and Red-Green-Blue (RGB) single-image files. It provides options for 256, and 17 million colors, or 17 million colors plus alpha channel. It does not support CMY, CMYK, HVS, and VLT color schemes.
The esource nterchange ile ormat is the storage structure commonly used for multimedia data on the Windows platform. It organizes data in chunks which each have a small header that describe the chunk type and size. This structure allows programs that do not recognize specific chunk types to skip over the unknown data and continue correctly processing known chunks in the file. Data chunks may contain smaller "sub-chunks" of data. In fact, all RIFF files are supposed to store all data chunks inside a master "RIFF" chunk that defines the type of resource data the file contains. WAVE and AVI files are examples of data stored in the RIFF format.
resource interchange file format. A tagged-file specification used to define standard formats for multimedia files. The tagged-file structure helps prevent compatibility problems that often occur when file-format definitions change over time. Because each piece of data in the file is identified by a standard header, an application that does not recognize a given data element can skip over the unknown information.
The Resource Interchange File Format (RIFF) is a generic meta-format for storing data in tagged chunks. It was introduced in 1991 by Microsoft and IBM, and was presented by Microsoft as the default format for Windows 3.1 multimedia files. It is based on Electronic Arts's Interchange File Format, introduced in 1985, the only difference being that multi-byte integers are in little-endian format, native to the 80x86 processor series used in IBM PCs, rather than the big-endian format native to the 68k processor series used in Amiga and Apple Macintosh computers, where IFF files were heavily used.
