ASPT is a software library containing a large collection of algorithms.
Editor: ASPT is a software library containing a large collection of both widely used industrial algorithms such as NLMS and FXLMS as well as advanced ones with improved performance and high computational efficiency such as PBFDAF and FTRLS. ASPT supports most digital filter structures including transversal, lattice, recursive, and some classes of nonlinear filters, such as second order Volterra adaptive filters. Both sample per sample and block processing filters are supported, with implementation in time and Frequency domains. Specialized algorithms for applications such as active noise and vibration control and beam forming are also included. Moreover, most ASPT functions are provided for single-channel as well as multi-channel systems.

We are pleased to announce releasing a free-of-charge version of the Adaptive Signal Processing Toolbox in both Matlab as well as C flavors. FREE-ASPT is an excellent way to learn more about adaptive filters and to gain practical experience in this field without spending a cent. The FREE-ASPT package includes 16 of the most used adaptive filters algorithms. FREE-ASPT also includes the source code of one application for each filter demonstrating the use of the library application programming interface. FREE-ASPT package also includes the documentation of the whole library. Although the number of filter coefficients in the FREE-ASPT version is limited, the package proved to be sufficient for many applications.

Package files includes the following:
Two dynamic Link libraries (DLL) providing the implementation of 16 adaptive filters in single and double Precision floating point arithmetic.
Include files containing the declarations of the adaptive filters.
C source code of a short application for each included adaptive filter.
