AFsp: Audio File I/O Routines

The AFsp package is a library of routines for reading and writing audio files. The emphasis is on providing support for the type of audio file used by the speech processing research community. The routines have been designed to be easy to use, yet provide transparent support the reading of several audio file formats. A secondary purpose for distributing these routines is to encourage the use of a standard audio file format for the header information in the output files. The following file formats are supported for reading. - NIST SPHERE audio files - Sun/NeXT audio files - DEC audio files - IRCAM SoundFiles - INRS-Telecom audio files - ESPS sampled data feature files - Headerless audio files The audio file open routine automatically senses the file type and communicates it to the audio file reading routines. Formats are converted on the fly as the file is read, so the user manipulates floats and doesn't need to worry about the underlying data format. For writing, the routines produce a standard format file, though options are available to produce headerless files if desired. This standard format is a compatible with the Sun audio file format. There is provision for storing extra information in the extensible part of the header. Several audio file utilities (for copying, comparing, and filtering audio files) are included in the package.
