libsndfile and GNU Octave

-

- GNU Octave is a high-level interactive - language for numerical computations. - There are currently two development streams, a stable 2.0.X series and a - development 2.1.X series. - Octave reads and writes data in binary formats that were originally developed - for - MATLAB. - Version 2.0.X of Octave uses binary data files compatible with MATLAB - version 4.2 while Octave 2.1.X uses binary data files compatible - with MATLAB version 5.0 as well as being able to read the older MATLAB 4.2 - format. -

-

- From version 1.0.1 of libsndfile onwards, libsndfile has the ability of reading - and writing a small subset of the binary data files used by both versions - of GNU Octave. - This gives people using GNU Octave for audio based work an easy method of - moving audio data between GNU Octave and other programs which use libsndfile. -

-

- For instance it is now possible to do the following: -

- - -

- Another example would be using the MAT4 or MAT5 file formats as a format which - can be easily loaded into Octave for viewing/analyzing as well as a format - which can be played with command line players such as the one included with - libsndfile. -

Details

-

- Octave, like most programming languages, uses variables to store data, and - Octave variables can contain both arrays and matrices. - It is also able to store one or more of these variables in a file. - When reading Octave files, libsndfile expects a file to contain two - variables and their associated data. - The first variable should contain a variable holding the file sample rate - while the second variable contains the audio data. -

-

- For example, to generate a sine wave and store it as a binary file which - is compatible with libsndfile, do the following: -

-
-        octave:1 > samplerate = 44100 ;
-        octave:2 > wavedata = sin ((0:1023)*2*pi/1024) ;
-        octave:3 > save sine.mat samplerate wavedata 
-
- -

- The process of reading and writing files compatible with libsndfile can be - made easier by use of two Octave script files : -

-
-        octave:4 > [data fs] = sndfile_load ("sine.mat") ;
-        octave:5 > sndfile_save ("sine2.mat", data, fs) ;
-
-

- In addition, libsndfile contains a command line program which which is able - to play the correct types of Octave files. - Using this command line player sndfile-play and a third Octave script - file allows Octave data to be played from within Octave on any of the platforms - which sndfile-play supports (at the moment: Linux, MacOS X, Solaris and - Win32). -

-
-        octave:6 > sndfile_play (data, fs) ;
-
-

- These three Octave scripts are installed automatically in Octave's site - script directory when libsndfile is installed (except on Win32) ie when - libsndfile is being installed into /usr/local, the Octave scripts will - be installed in /usr/local/share/octave/site/m/. -

- -

- There are some other Octave scripts for audio to be found - here. -
