iff, 8svx - Amiga IFF/8SVX Audio File Format
As shipped in IRIX 6.5.19. Unchanged since IRIX 6.5.
NAME iff, 8svx - Amiga IFF/8SVX Audio File Format SYNOPSIS #include <dmedia/audiofile.h> DESCRIPTION The Audio File Library currently supports 13 of the commonly found audio file formats, i.e., is able to recognize, read, and write sample data and header information to and from files in these formats. It is important not to confuse sample or audio data formats with file formats. The former refers to the bit-wise organization of the sound samples in the file, i.e., whether the format is 8-bit integer or 16-bit unsigned, etc. Audio file format refers to the structure of the audio file header, the chunk of on-disk data which preceeds the samples and which provides information about the file to the audio program. A single audio file format may support a large variety of sample formats. The Amiga IFF/8SVX File Format (iff) is used primarily on Amiga computers. It consists of a variable-length header followed by a contiguous block of binary data representing the sound samples. Occasionally, additional chunks of non-audio information will be placed after the sound sample block. DATA FORMAT SPECIFICATIONS Sample Formats: Two's complement integer only. Sample Widths: 8-bit only (for now). Byte Orders: Always bigendian. Channel Counts: Monaural files only (for now). Compression Formats: The only available compression, Fibonacci-delta encoding, is not currently supported by the Audio File Library. FILE FORMAT SPECIFICATIONS IFF/8SVX file headers can contain additional information. Instrument Configurations: None supported. Markers: None supported.
