LUTEar Core Routines Library 1.0.0 - for auditory simulation investigations.

  Please find below the README file for the Core Routines Library mentioned
above.  The UNIX and Macintosh (THINK C) platform versions are now
available via anonymous FTP from:-

        suna.lut.ac.uk ( /public/hulpo

  Connect via FTP then login with user name "anonymous" and give your
e-mail address as the password.  Download and read the "lutear100.INSTALL"
file from the "/public/hulpo" directory, then follow the installation
procedure for your platform.  If you have any problems at all, do not
hesitate to get in contact with me.

  Any comments, improvements, additions or corrections you may wish to
suggest are very welcome; it is only by direct feed-back from users that I
can ensure that the Core Routines Library is a delight to use, as well as
implementing state of the art auditory models.


1       Introduction

        The auditory models developed by the Speech and Hearing
Laboratory, at Loughborough University of Technology (UK.), have
received much attention, due principally to their simple form and
the many published papers in which the models are used to
explain auditory phenomena.  The many requests for the
computer code of the model simulations has led to the group to
release the LUTEar Core Routines Library (CRL, version 1.0).  The
library brings together established models, developed by the
group, and contributed by other researchers in the field, which
simulate various stages in the auditory process.

        The library has a modular structure which can be used to
create auditory investigation/application systems or incorporated
in existing code, as required.  All the modules conform to a simple
standard format; it is a development based on the meld of
experimental investigation methods and the tenants of good
software engineering practice;  the library is intuitive in
application, and has comprehensive error reporting embedded in
efficient code.

        Included with this release are a comprehensive series of test
programs.  These programs were used to test the CRL routines;
they reproduce the published behaviour of the respective models
included.  The programs also provide examples of how the CRL
may be used in auditory investigation programs.  In addition the
programs read data from parameter files, and thus can be readily
used to investigate further the behaviour of the models included
in the CRL.

        At the time of writing there are no known major
shortcomings in the CRL that have not been fixed, due to careful
and exhaustive testing.  No system, however, is infallible so it is
hoped that, with the gentle admonitions of the library's users, any
problems or omissions will be quickly corrected.  In addition it is
expected that the library will be augmented by further models as
the scientific endeavour continues.

1.1     List of CRL Features

(i)     Modular Structure.
(ii)    Processing stage data can be handled by a single unit.
(iii)   Processing stage units can link to data from other stages.
(iv)    Multichannel data is handled invisibly.
(v)     Efficient algorithms are used throughout.
(vi)    Meaningful routine and variable names are used.
(vii)   All routines are prefixed by their module name.
(viii)  Comprehensive error handling incorporated in routines.

2       Installation.

        Read the file lutear.INSTALL for installation instructions.
