# audio/iir1 - The NetBSD Packages Collection

DSP IIR Realtime C++ filter library

    An infinite impulse response (IIR) filter library for Linux, Mac OSX and Windows
    which implements Butterworth, RBJ, Chebychev filters and can easily import
    coefficients generated by Python (scipy).

    The filter processes the data sample by sample for realtime processing.

    It uses templates to allocate the required memory so that it can run without any
    malloc / new commands. Memory is allocated at compile time so that there is
    never the risk of memory leaks.

    All realtime filter code is in the header files which guarantees efficient
    integration into the main program and the compiler can optimise both filter code
    and main program at the same time.
