Basically, you need a Unix (Linux) system with a working soundcard that is capable of full duplex with an OSS driver.

When using Linux, your kernel needs SYSV IPC. Soundcards tested in 16 bit full duplex mode are:

• Creative SoundBlaster AWE PCI. SB-64 PCI and SB-128 PCI
• Gravis UltraSound MAX PnP.
• Ensoniq SoundScape [Basis for some Creative SoundBlaster 64/128 PCI series].
• Cirrus Chipsets.
• Yamaha OPL3-SAx.

Until 3.0 SLab was developed on a P133 16 MB system, but it now generally gets tested on P300/P450 systems, your mileage is CPU dependent. Get gobs of disks if you want to do some real recording, 16 tracks CD quality requires about 80MB a minute. Compression can be applied to reduce this requirement by up to a factor of 4, at a consequent loss of signal quality since the compression algorithms are all lossy.

GUI is based on TCL/TK, and has been reved to 8.0.

You DO NOT need TCL/TK installed to use this application, it should be complete. The required TCL/TK header files can be found in the SLAB_HOME/tcl.files directory. Either use the "startSLab" script provided with the distribution, or point your TCL_LIBRARY and TK_LIBRARY environment variables at this directory.
