SoX Installation ---------------- This distribution will compile and run on most commonly-used systems. It was originally developed on a UNIX/386 machine running AT&T V3.2 but it's currently developed under Linux. With a little work it should work with most POSIX systems. Compiling using a POSIX system ------------------------------ [Only if you're compiling the CVS sources, first make sure you have the GNU autotools installed (automake >= 1.9, autoconf >= 2.59) and run autoreconf -i ] The preferred method for compiling SoX is to use the "configure" scripts compatible with most UNIX systems that contain "/bin/sh" or equivalent (it can also be used on Windows with Cygwin). To compile and install SoX on these platforms run the following commands: ./configure make make install Optionally, to test the executable: make installcheck (At the moment you can't run "make check", because when built modularly SoX can't use its format and effect modules until it is installed.) There are several optional parameters that you may pass to the configure script to customize SoX for your applications. Run ./configure --help for a complete list of options. In addition, there are several optional make targets that can be used (run as "make target"). They include: pdf, html, install-pdf, install-html Compiling using Microsoft's Visual C ------------------------------------ o Install cmake (http://www.cmake.org/HTML/Download.html) o Install any optional libraries to use with SoX o Unpack the SoX sources (...tar.gz) to say c:\sox o Type cd c:\sox o Type cmake . This should generate project build files for use with Visual C. Optional Compile Features ------------------------- SoX can make use of some external libraries to obtain support for additional file formats and/or effects. Some optional libraries may require pkg-config to be installed to be properly detected. SoX can detect and use the following libraries: Ogg Vorbis - http://www.vorbis.com Lame MP3 encoder - http://lame.sourceforge.net MAD MP3 decoder - http://www.underbit.com/products/mad FLAC - http://flac.sourceforge.net AMR-NB/WB - http://www.penguin.cz/~utx/amr libsndfile - http://www.mega-nerd.com/libsndfile ffmpeg - http://ffmpeg.mplayerhq.hu libao - http://xiph.org/ao Secret Rabbit Code - http://www.mega-nerd.com/SRC LADSPA - http://www.ladspa.org WavPack - http://www.wavpack.com PNG - http://www.libpng.org/pub/png Configuring Optional Compile Features (POSIX system) ---------------------------------------------------- If any libraries are installed in a non-standard locations in your system then you can use the CPPFLAGS and LDFLAGS variables to allow configure to find them. For example: ./configure CPPFLAGS="-I/home/sox/include -I/usr/local/multimedia/include" LDFLAGS="-L/home/sox/lib -L/usr/local/multimedia/lib" If you are compiling under cygwin and would like to create a static sox.exe using mingw libraries then you can use the following: ./configure CC="gcc -mno-cygwin" --disable-shared The next cygwin example is used to build the cygwin version of SoX that is distributed by the project. It tells gcc to prefer static libraries over dynamic ones and to use some static libraries compiled manually and installed under /usr/local. ./configure LDFLAGS="-static -L/usr/local/lib" CPPFLAGS=-I/usr/local/include You can run "cygcheck.exe src/sox.exe" after compiling to see which dynamic DLL's will be required to be distributed with the cygwin executable. Newer versions of SoX include support for loading libraries for file formats at runtime. If you experience problems with this then you may wish to revert back to the older compile-time support. To stick with old behavior use: ./configure --without-libltdl Testing ------- NOTE: If SoX was compiled with libltdl support then it will not run correctly from within the source file directory and must be first installed. Once install, it can be ran from the source directory. Either install before running the following tests or configure with --without-libltdl temporarily. After successfully compiling SoX, try translating a sound file. You should also playback the new file to make sure it sounds like the original. You can either use an external program or SoX itself if compiled with playback support. To work with widest range of playback programs, you should chose a format that is native to your OS; such as .wav for Windows or .aif for MacOS. In the following example, we'll use .xxx as the extension of your preferred format. cd src ./sox monkey.wav monkey.xxx You may have to give the word size and rate for the file. For example, this command will make a sound file with a data rate of 12,500 samples per second and the data formatted as 2-byte (16-bit) signed integers: ./sox monkey.voc -r 12500 -2 -s monkey.xxx If playback support was compiled in then it can be played like this: ./play monkey.xxx If monkey.xxx plays properly (it's a very short monkey screech), congratulations! SoX works. If you're adding new features to SoX or want to perform advance tests on a new platform then you can use the scripts "tests.sh" and "testall.sh" to stress SoX. Appendix: How To Compile SoX with MP3 Support on Win32 ------------------------------------------------------ The following text, untested by the SoX team, was originally written by `Enter AG' and released to the public domain. = How To Compile Sox with MP3 Support = == Requirements == The following requirements have been tested. Nevertheless, other versions may work as well. o Microsoft Windows (Win32, Win2k, Win2003). o CMake (Cross Platform Make) version 2.4 available on [http://www.cmake.org] o Microsoft Visual Stuio 2008 (also earlier Versions) o SoX source distribution version 14.0.1 available on [http://sox.sourceforge.net] o LAME source distribution version 3.97 available on [http://lame.sourceforge.net] o MAD source distribution version 0.15.1b available on [http://www.underbit.com/products/mad/] == Compilation Procedure == === Compilation of the LAME libraries === o Extract the LAME source distribution and open it as a Visual Studio project using the VS file in the top directory. o Set the ''libmp3lame'' "Configuration Properties -> C/C++ -> Code Generation -> Runtime Library" to Multi-threaded DLL (/MD). o Do the same for ''mpglib'' . o Build ''libmp3lame'' and ''mpglib.'' o Rename the static library libmp3lame.lib to mp3lame.lib. o Create a folder somewhere with an arbitrary name. We used the name "lameforsox". Create in this folder a new folder called "lame" and copy the lame.h header file into it. Copy mp3lame.lib and mpglib.lib in the lameforsox folder. Now you should have prepared the lame components for further use like this: ...\[somewhere]\lameforsox\ mp3lame.lib mpglib.lib \lame\ lame.h === Compilation of the MAD library === o Compile ''libmad'' with the same "Runtime Library" settings as described for LAME (previous section Compilation of the LAME libraries). o Rename the static library libmad.lib to mad.lib. === Compilation of SoX with the LAME and MAD libraries === o Open Visual Studio and add in "Tools -> Options -> Projects and Solutions -> VC++ Directories" in the "Include Directories" collection the folder containing the MAD header file mad.h and the folder containing lame/lame.h (...\[somewhere]\lameforsox). Add in the "Library files" collection the folder containing mad.lib and the folder containing the lame libraries mp3lame.lib and mpglib.lib (...\[somewhere]\lameforsox). o Edit the CMakeLists.txt in the SoX top directory: Add set(CMAKE_REQUIRED_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} mpglib) after some blank lines beneath the statement if(NEED_LIBM) set(CMAKE_REQUIRED_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} -lm) endif(NEED_LIBM) o Open the windows command line console and change into the SoX top directory. o Execute cmake like this: cmake.exe ./ -G "Visual Studio 9 2008" o If the Visual Studio settings are done as described above the following cmake output should appear: ... include files HAVE_MAD_H1 – found mad_stream_buffer in madmad_stream_buffer in mad – found ... include files HAVE_LAME_LAME_H1 – found lame_init in mp3lamelame_init in mp3lame - found ... o If not check CMakeFiles\CMakeError.log. o Open Visual Studio and open the SoX solution file in the SoX top directory (sox.sln). o Rebuild "ALL_BUILD" and confirm all "File Modification Detected" dialogs with "Reload". o Add in the libsox "Preprocessor Definitions" (right click on libsox -> Properties -> Configuration Properties -> C/C++ -> Preprocessor) HAVE_STRING_H before the first line. Set the "Runtime Library" to Multi-threaded DLL (/MD) as described above. o Do the same for sox and add in the "Additional Dependencies" (Linker -> Input) after the last line mpglib.lib. o Now build libsox o and then sox. o Sox now prompts "mp3, mp2" in the usage output in the section "SUPPORTED FILE FORMATS".
