To use this Linux library with Quisk, enter "make". It supports the NR2 and SNB features. The resulting libwdsp.so file is used in-place. No installation is necessary. For Windows, the libwdsp.dll file is included in the quisk directory. The WDSP library was originally written for Windows by Warren Pratt, NR0V. John Melton, g0orx/n6lyt, contributed a Linux port. Christian, DL1YCF, contributed further improvements.
