IIR is a C++ library that implements fast IIR filters: bandpass, bandstop, lowpass, and highpass. These can be designed using popular analogue filter functions such as Butterworth, Bessel, Chebyshev, Elliptic, Legendre, and pole placement. Creation of a complete filter requires only a single command and filtering is performed with a single function taking a sample and returning its result instantly. The library is template-based and avoids new/mallocs throughout. This library has been adapted form Vinnie Falco's original work and has been converted to run on Unix systems and turned into a realtime causal filter.

tblutils is a collection of several utilities for working with tabular text files: data written in plain text, with one row per line and columns separated by a common character (usually TAB or semicolon). It complements the usual Unix tools like cut and paste by providing enhanced versions that support column labels through-out, so that you can extract columns by name (tblcut), filter data using a mathematical expression (tblfilter), re-order columns without caring about the column index (tblcsort), join multiple files on a common index without having to pre-sort them (tblmerge), and much more.
