Basic Fortran module for reading .WAV file samples and metadata.

Install

If you want the defaults (library installed in /usr/local/lib/ and mod file in /usr/local/include/) just:

$ git clone https://github.com/SarKing/wavMF
$ cd wavmf
$ make
$ sudo make install

You can change the installation folder by editing the firsts lines of the Makefile

Uninstall

If you installed with the defaults just:

$ sudo make uninstall 

Change the Makefile accordingly with your installation path.

Usage

Disclaimer

There is no error handling and it (natively) only works with 2-channel 16-bit .WAV files. This is one of my first attempts at coding with Fortran, so don't expect much.

Library

If you installed the library (using the Makefile) you can compile your code indicating the path of the .mod file, i.e. (using gfortran)

$ gfortran -c foo.f90 -I /usr/local/include/

And then link indicanting the lib path

$ gfortran foo.o -L /usr/local/lib -lwavmf

Note tha you can also skip the installation and use the .mod and .o files located in the mod/ and /obj folder after compilation with the Makedile.

Module

All the functions in the library are documented in the source code, here is just an overview:

openwav(filename) -> Open the wav file.
getnchannels(fileunit) -> Reads the number of channels.
getfs(fileunit) -> Reads the sampling frequency.
getbitspersample(fileunit) -> Reads the bits per sample of the recording.
getdatasize(fileunit) -> Calculates the number of samples that each channels has.
readwavdata(fileunit) -> Reads the samples as they are in the file.
audioread(fileunit) -> IDEM as readwavdata but returns the samples as normalized reals.
