This document includes a brief background to the LUTEar Core Routines Library (CRL), which follows this section. A basic outline physiology of the auditory process is given for those not familiar with this field. It is by no means a detailed account; it serves only to provide the basis for the development of the CRL for those not familiar with the field. Only a short description of the installation and use of the CRL is necessary. Information is given for use under UNIX, Apple Macintosh (Think C 5.0) and MSDOS environments, although the library can be installed with little difficulty on other platforms as the source code is supplied. There then follows the introduction of a general program, "AudPer86" which is a basic auditory periphery simulation program. This program is presented as an example of a simulation program using the CRL. The program itself can be used as a backbone to more substantial projects.
Having illustrated how the CRL may be used, the overall structure of the library is presented, introducing all the basic module groups and the parts they play. Included with this distribution are test programs which demonstrate the particular properties and behaviours of each module. It is therefore possible to cut and paste sections of these programs in custom application/simulation programs. The document ends with the CRL reference in which all the modules, and their respective routines, are listed with descriptions of how they are used and what they do.
