Snack v2.2 - a sound toolkit for scripting languages Kre Sjlander Introduction ------------------------------------------------------------------- Snack is a sound processing toolkit designed as an extension to a scripting language. Snack currently works with the scripting languages Tcl/Tk, Python, and Ruby. Snack has commands to play, record, process, and visualize sound. Snack provides high level sound objects, with flexible storage management, and streaming support. It handles most common sound file formats. The visualization canvas item types update in real-time and can output postscript. The same scripts run on Unix (Linux, Solaris, HP-UX, IRIX, FreeBSD, NetBSD), Macintosh, and Windows 95/***/NT/2000/XP. Several example scripts can be found in the demos directory. For more information on Tcl/Tk and Python see Tcl/Tk: http://tcl.activestate.com/ Python: http://www.python.org/ In order to use Snack you must have Tcl and Tk version 8.0 or later. Always use the latest stable release, currently 8.4.1, which can be downloaded from ftp.activestate.com/ActiveTcl/html/. Tcl/Tk is often included with Python distributions. Snack has been tested with Python 1.5.2 - 2.2 on Linux and Windows. See the Python section below. The Snack package has been tested on the following platforms: Windows 95/***/NT/2000/XP Linux 2.0.35 (OSS 3.5) - 2.4.18-4 (OSS 3.8.2/ALSA 0.9.0) (x86 & PowerPC) SunOS 5.5.1 (Sparc and x86), Solaris 8 (Sparc) HP-UX B.10.20/11.00 IRIX 6.2, 6.3 & *** (even runs under SoftWindows, although slowly) NetBSD-current/i386 using the OSS emulation library BSD/OS-4.1 MacOS X, MacOS 8.6 and later Make sure you have the latest Snack version available at http://www.speech.kth.se/snack/ before proceeding with the installation. Compilation instructions for Snack on Unix (see mac/README for OS X) ------------------------------------------------------------------- You must have Tcl/Tk installed on your system. Both Tcl and Tk must have been configured with the "--enable-shared" flag at build time (this is default for the 8.4 versions). Build them before Snack. Unpack Snack and change directory to the snack2.2.2/unix directory. Type "./configure". If you get this error message "Can't find Tcl configuration definitions", you have to specify their locations using the options "--with-tcl" and "--with-tk" when running configure. For example, use "--with-tcl=/usr/lib --with-tk=/usr/lib" if Tcl/Tk was installed in "/usr/lib", or "--with-tcl=../tcl8.4.1/unix" if you use that version. Linux users who have the ALSA sound driver installed should specify the configure flag --enable-alsa in order to enable native ALSA support. Type "make". If the make fails you will have to edit the Makefile and possibly also the configure script. TCL_INCPATH should be the path to the directory which contains the Tcl header file (tcl.h). The same goes for TK_INCPATH (tk.h). XINCLUDES should be the path to the directory containing the X11 include files. If you use Tcl/Tk 8.0 to 8.0.5 you will have to use the flag --disable-stubs, when configuring Snack. Summary in case you download Tcl, Tk, and Snack and build from scratch: You should place the distributions in the same directory and unpack them. Build Snack using the following commands: cd tcl8.4.1/unix ./configure --enable-shared cd ../../tk8.4.1/unix ./configure --enable-shared cd ../../snack2.2.2/unix ./configure make Testing ------------------------------------------------------------------- When you have succesfully compiled Snack it's time to look at the demos. In order to run these you will have to set the environment variable TCLLIBPATH to the directory containing the Snack library files (you don't need this step if you install Snack as described below). If you have compiled Snack in /u/kare/snack2.2.2/unix, this would be: setenv TCLLIBPATH /u/kare/snack2.2.2/unix Change to the demos/tcl/ directory and type ./widget.tcl: cd ../demos/tcl/ ./widget.tcl this runs the Snack widget demonstration. You should also try the Snack test suite. Type: make test in the build directory. You should then see a printout of the test files processed. If any errors occur, you'll see a much more substantial printout for each error. Please report any problems to the author. System wide installation ------------------------------------------------------------------- The recommended installation directory is the standard Tcl package directory. You can determine this by typing: tclsh puts $tcl_pkgPath If you choose this directory you don't have to set the TCLLIBPATH variable. Edit the Makefile if necessary. SNACK_INSTALL_PATH should be the path to the directory where you want to install the Snack package (e.g. /usr/local/lib). Install using: make install Compilation instructions for Snack on Windows ------------------------------------------------------------------- The MSVC++ 6.0 workspace and project files necessary to build Snack on Windows are located in the win directory of the source distribution. In order to use Snack you will have to install Tcl/Tk 8.4 first. Snack's project files are set up for use with Tcl installed in C:\Tcl\, it might be easiest to change such paths by editing all *.dsp files in a text editor. Don't forget to copy the files snack.tcl and pkgIndex.tcl.dll from the unix directory to C:\Tcl\lib\snack2.2\ and rename the last file pkgIndex.tcl Using Snack with Python ------------------------------------------------------------------- Snack must currently be used in conjunction with Tkinter. You need to have a matching installation of Snack and Tcl. For example, Python 1.5.2 uses Tcl8.0.5 and Python 1.6-2.2 uses Tcl8.3 on Windows. For Unix you have to edit Modules/Setup before building Python to specify which Tcl version to use. The default is Tcl8.0. You can check this by typing the following lines at the Python prompt: import Tkinter Tkinter.Tk().tk.eval('info tclversion') Snack is accessed using the tkSnack module located in the python directory. You need to put the file tkSnack.py in your Python path. Some demos can be found in demos/python/. Documentation is found in doc/python-man.html Using Snack with NIST/Sphere file formats ------------------------------------------------------------------- It is possible to configure Snack to create an additional package for handling the NIST/Sphere file formats. Use the configure options --with-nist-include and --with-nist-lib to specify the locations of the corresponding directories of the NIST/Sphere distribution, which can be downloaded at ftp://jaguar.ncsl.nist.gov/pub/sphere_2.6a.tar.Z. In the Sphere distribution you will have to modify the file src/scripts/install.sh and add the compilation flag to create position independent code in some cases. Look at the Snack Makefile for these. On HP-UX with HP cc use: -Ae +z Linux users should specify platform: 10 (Custom), compiler flags: -O -Wall -fPIC, architecture: INTEL,and comment the line "extern char *sys_errlist[];" in nist/src/lib/sp/exit.c See SphereFile.txt for more info. Windows users can get a compiled dll at the address http://www.speech.kth.se/~kare/libsnacksphere.dll Put it in ..Tcl\lib\Snack2.2 (together with libsnack.dll). Linux users get a compiled library at the address http://www.speech.kth.se/~kare/libsnacksphere.so Put it in the Snack installation directory (together with libsnack.so). Using Snack with the OGG/Vorbis file format ------------------------------------------------------------------- It is possible to configure Snack to create an additional package for handling the OGG/Vorbis file format. Use the configure options --with-ogg-include and --with-ogg-lib to specify the locations of an existing OGG/Vorbis installation. More information about OGG/Vorbis available at http://www.vorbis.com/ Windows users can get a compiled dll at the address http://www.speech.kth.se/~kare/ogg.tar.gz Put libsnackogg.dll in ..Tcl\lib\Snack2.2 (together with libsnack.dll). Linux users can get a compiled library at the address http://www.speech.kth.se/~kare/ogg.tar.gz Put libsnackogg.so in the Snack installation directory (together with libsnack.so). When building Ogg/Vorbis from source on Unix note that some modifications to the Makefiles might be necessary. Specify "AM_CPPFLAGS=-I$prefix/include" "LDFLAGS=-L$exec_prefix/lib" to get them to find their own installed headers and libraries. On Solaris force libvorbis to use the native compiler and add -Dalloca=__builtin_alloca to prevent the system from using a non-existing alloca. Dynamic linking problems ------------------------------------------------------------------- (Sun, Linux, and SGI) The loader must be able to find the "libsnack.so" shared object. You may have to set the environment variable LD_LIBRARY_PATH to point the directory where it is located. This variable is a colon separated list of paths which can be modified using setenv. If you, for example, have compiled Snack in the directory /u/kare/snack/unix and have the shared objects libtcl8.4.so and libtk8.4.so in /usr/local/bin you would use the following command at the terminal prompt or in your .cshrc file: setenv LD_LIBRARY_PATH /u/kare/snack/unix:/usr/local/bin:$LD_LIBRARY_PATH (HP) The corresponding environment variable on HP-UX systems is SHLIB_PATH and shared objects use ".sl" as file extension. License ------------------------------------------------------------------- Snack is currently licensed under GPL, see the file COPYING. Contact the author if this kind of license is a problem. The only reason for GPL is the MPEG decoding code, see jkFormatMP3.c. If you remove that code it is possible to use a license similar to the one Tcl/Tk uses (BSD style) and to include Snack in any software on the same terms.
