The ShARC HPC cluster was decommissioned on the 30th of November 2023 at 17:00. It is no longer possible for users to access that cluster.


Libsndfile is a C library for reading and writing files containing sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format) through one standard library interface. It is released in source code format under the GNU Lesser General Public License (GPL).

It was designed to handle both little-endian (such as WAV) and big-endian (such as AIFF) data, and to compile and run correctly on little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well as big-endian processor systems

libsndfile has the following main features:

  • Ability to read and write a large number of file formats.

  • A simple, elegant and easy to use Applications Programming Interface.

  • Usable on Unix, Win32, MacOS and others.

  • On the fly format conversion, including endian-ness swapping, type conversion and bitwidth scaling.

  • Optional normalisation when reading floating point data from files containing integer data.

  • Ability to open files in read/write mode.

  • The ability to write the file header without closing the file (only on files open for write or read/write).

  • Ability to query the library about all supported formats and retrieve text strings describing each format.


To make this library available, run the following module commands

module load libs/libsndfile/1.0.28/gcc-4.9.4

This also activates version 4.9.4 of the GCC compiler suite.
