SoX

This file contains information specific to the MacOS X version of SoX. Please refer to the README file for general information.

The sox executable can be installed anywhere you desire. It is a self-contained statically linked executable.

If the sox executable is invoked with an executable name of soxi, play, or rec it will perform the functions of those applications as defined in included documents. Symlinks are included with this package but you can also make your own.

Appendix - wget Support

SoX can make use of the wget command line utility to load files over the internet or listen to shoutcast streams. It only needs to be somewhere in your path to be used by SoX.

Please consult wget's homepage for access to source code as well as further instructions on configuring and installing.

Appendix - MP3 Support

SoX contains support for reading and writing MP3 files but does not ship with the dylib's that perform decoding and encoding of MP3 data because of patent restrictions. For further details, refer to:

http://en.wikipedia.org/wiki/MP3#Licensing_and_patent_issues

MP3 support can be enabled by placing Lame encoding library and/or MAD decoding library into a standard library search location such as /usr/lib or set LTDL_LIBRARY_PATH to location.

These can be compiled yourself, they may turn up on searches of the internet or may be included with other MP3 applications already installed on your system. Try searching for libmp3lame.dylib and libmad.dylib.

Obtain the latest Lame and MAD source code from approprate locations.

Lame MP3 encoder http://lame.sourceforge.net MAD MP3 decoder http://www.underbit.com/products/mad

If your system is setup to compile software, then the following commands can be used. Note: since SoX is distributed as a 32-bit i386 binary, the library must match that format as well:

cd lame-398-2 ./configure CFLAGS="-arch i386 -m32" LDFALGS="-arch i386" make sudo make install

cd libmad-0.15.1b ./configure CFLAGS="-arch i386 -m32" LDFALGS="-arch i386" make sudo make install

Appendix - AMR-NB/AMR-WB Support

SoX contains support for reading and writing AMR-NB and AMR-WB files but does not ship with the DLL's that perform decoding and encoding of AMR data because of patent restrictions.

AMR-NB/AMR-WB support can be enabled by placing required libraries into a standard library search location such as /usr/lib or set LTDL_LIBRARY_PATH to search path.

These can be compiled yourself, they may turn up on searches of the internet or may be included with other AMR applications already installed on your system. Try searching for libopencore-amrnb.dylib and libopencore-amrwb.dylib.

Obtain the latest amrnb and amrwb source code from http://sourceforge.net/projects/opencore-amr

cd opencore-amr-0.1.2 ./configure CFLAGS="-arch i386 -m32" LDFALGS="-arch i386" make sudo make install

If that does not work, then try this:

cd opencore-amr-0.1.2 ./build_osx.sh

Appendix - LADSPA Plugins

SoX has built in support for LADSPA Plugins. These plugins are mostly built for Linux but some are available for OS X. The Audacity GUI application has a page that points to a collection of OS X LADSPA plugins.

http://audacity.sourceforge.net/download/plugins

SoX will search for these plugins based on LADSPA_PATH enviornment variable. See sox.txt for further information.
