Digital Signal Processing Algorithm Library
DSPL-2.0 — opensource cross-platform digital signal processing algorithm library, written in C language.
Distributed under LGPL v3 license. This allows to use this library in all applications with dynamic linking.
Source codes are available on SourceForge.
DSPL-2.0 includes follow algorithms sets:
- Digital spectral analysis, discrete and fast Fourier transform algorithms.
- Analog and digital IIR filters design and analysis.
- Digital FIR filters design and analysis.
- Windows function collection includes 15 different parametric and nonparametric window functions.
- Digital Hilbert transform algorithms.
- Mathematical sections includes trigonometric, hyperbolic, elliptic functions of real and complex variables.
- Pseudorandom numbers generation algorithms.
- Statistic functions.
- Linar algebra algorithms (BLAS and LAPACK packages are used under the hood of the DSPL-2.0 library).
- Digital resampling algorithms.
To build the DSPL-2.0 library on Windows, a special set of programs dsplib toolchain is provided. Dsplib toolchain includes GCC, GNUPLOT, CodeBlocks IDE, Far file manager and also Unix utilities for Windows OS.
