Software for playback is a bit of a mixed bag right now, and with the imminent upgrade to 24 bit digitizing, which will necessarily involve a data format change, efforts to improve the situation are on hold. Meanwhile, the following codes are available:

SimpleLCdump.f is ANSI standard FORTRAN code which is pretty bullet-proof but will only read uncompressed, fixed gain data from a binary disk image file. However, almost all the MT data distributed by Steven Constable or AOA Geophysics is in this format.

This code will run as is on a (wonderful) Macintosh computer or a (useful) Unix workstation. If you have a (expletive deleted) IBM-type PC, then you need to set the pc = .false. switch to pc = .true. so that the data bytes get reversed.
