contains the source code for library itself. + +The doc/ directory contains the libsndfile documentation. + +The examples/ directory contains examples of how to write code using +libsndfile. 'wav32_aiff24' converts a WAV file containing 32 bit floating +point data into a 24 bit PCM AIFF file. 'sndfile2oct' dumps the audio +data of a file in a human readable format. 'sfconvert' is the beginnings +of a audio file format conversion utility. 'make_sine' generates a WAV +file containing one cycle of a sine wave with 4096 sample points in +32 bit floating point format. 'sfinfo' opens a sound file and prints +out information about that file. + +The tests/ directory contains programs which link against libsndfile +and test its functionality. + +The Win32/ directory contains files and documentation to allow libsndfile +to compile under Win32 with the Microsoft Visual C++ compiler. + +The src/GSM610 directory contains code written by Jutta Degener and Carsten +Bormann.
