Hi All,

Could anyone recommend a good library for filters (or DSP library including filters)?

I have tried VinnieFalco’s library ([GitHub - vinniefalco/DSPFilters: A Collection of Useful C++ Classes for Digital Signal Processing](https://github.com/vinniefalco/DSPFilters)) but it seems this library is no longer maintained and has references to TR1 which I believe is now deprecated?

Any suggestions would be massively appreciated.

Thanks,  
James

I am currently using [GitHub - berndporr/iir1: DSP IIR realtime filter library written in C++](https://github.com/berndporr/iir1).  
It’s great, it’s reliable, it’s efficient, it’s exceedingly easy to use, it’s actively maintained, and the developer responds quickly to requests for help!

Let me know if you need help with it 🙂
