Voice4Fun is an iPhone/iPod application using a software package licensed under the General Public License (GPL) version 2 of the Free Software Foundation:
"SoX" version 14.0.1 by Lance Norskog and others
Source files are not distributed during the iPhone installation procedure because it would be useless as they could be not directly accessible by the iPhone user; therefore, to respect the GPL terms, they are provided here or can be requested by anybody to the author (info@geomago.com or g.difalco@iseo.it).
SoX, a library for managing sound effects, was sligthly modified for solving some integration problems (that might have been solved in some other way too). Neither additions nor improvements were done to SoX functionalities. The Sox objects used by Voice4Fun are contained in the SOX subdirectory of the project folder; the (few) modifications are marked in the source code with /*$$gdf$$*/.
And finally, here are the source files:
- Voice4Fun 1.1 project (zipped XCode project directory)
- Sox vers. 14.0.1 original source code download; see also sox.sourceforge.net
