This is the software for the Open Source Audio Library Project. This is a beta release. It is hoped that this program will inspire others to join the Open Source Audio Library Project to build a first class set of C++ classes and libraries to handle all the fundamentals of a sound application. Any questions should be directed to: Darrick Servis darrick@kdvs.org OSALP was originally designed and created by Bruce Forsberg. REQUIREMENTS Currently this library is known to run on: Linux on Intel Linux on Sparc FreeBSD Solaris Sparc Reports of other successes are welcome. This version requires the following software: Motif or Lesstif (To build the sample applications) -- Lesstif available from http://www.lesstif.org -- Motif available from http://www.opengroup.org/openmotif C++ Compiler with STL (Standard Template Library) Different file formats require the following MPEG player (mpg123 version 0.59r or later, for the mpg123 module) -- Available from http://www.mpg123.de MPEG encoder (lame version 3.51 or later, to record mp3's) -- Available from http://www.sulaco.org/mp3 MPEG encoder (blade version 0.91 or later, to record mp3's) -- Available from http://bladeenc.mp3.no COMPILE & INSTALLATION To compile perform the following at this directory: ./configure make make install (as root) For SOLARIS: If you use gcc and have installed it in /usr/local then you might need to set the following: setenv LD_LIBRARY_PATH /usr/local/lib setenv LD /usr/local/bin/g++ For FreeBSD For the sample applications you will need to remove the -ldl line from the Makefiles. This version currently only supports Linux, FreeBSD, and Solaris Sparc. Reading and writing to audio files and devices is done via stand-alone modules and you can choose which ones to install. The configure script by default will try to compile and install as many as are supported on your machine. -- Audio Devices --- OSS Device (Linux and FreeBSD) Solaris Sparc sound device -- Formats Based on the Audiofile Library -- MS Wave format AIFF AIFF-C AU NOTE: the audiofile library is included as source in this distribution. -- Formats readable by the soundtools library module -- SGI/Apple AIFF Sound File a-law byte raw ALSA /dev/snd/pcmXX Device SPARC .au with header Sox Module Sound File Detection CDDA Audio Cont. Varible Slope Delta Cont. Varible Solot Delta Text Data Samples GSM 06.10 Mac FSSD/HCOM Inverse a-law byte raw Inverse u-law byte raw Amiga MAUD Amiga 8SVX Sound Blaster .VOC Microsoft RIFF Pison .wve Yamaha TX16W and SY99 Sound Files OSS /dev/dsp Device Raw File. Must specify rate, channels and byte type. Raw Signed Bytes Raw Signed Longs IRCAM Sound File SampleVision Sound File Sndtool Sound File NIST Sphere Sound File Sun /dev/audio Device NOTE: To compile the aflibSoxFile module. Download sox-12.17.3 or higher. http://sourceforge.net/projects/sox untar sox source. configure and compile sox (you don't need to install it). cd to the root of the osalp source. ./configure --with-libst= make make install compile and install the aflibSoxFile module. -- Misc. Formats -- MPEG reader (one module based on mpg123 the other on Jung woo-jae's MPEG/WAVE library). MPEG writer (one module based on lame the other on blade). OGG-VORBIS (uses ogg-vorbis library). NOTE: The aflibLameFile uses the Lame encoder to write mp3's. The aflibBladeFile uses the Blade encoder to write mp3's. If you use either of the mp3 formats then you will need to make sure that your PATH environment variable is set to where these applications are located. The mpg and mpg123 modules read mp3's. SAMPLE APPLICATIONS There are three sample applications. They are in the player, editor, and osalp directories. Perform a "make" in these directories in order to run these. Then execute the s script to run the program. There are many combinations with the sample application that don't work right. These will be fixed in due time. LICENSE Each source file should be examined to determine what license applies. All the code under formatlib and aflib is LGPL (see COPYING.LIB in this directory) except the FFT class which is in the public domain. The source code in app, editor, and player is in the public domain since they serve as examples of how to use this library.
