- Travis:
- AppVeyor:
A rewrite of the digital filter components of SPUC with more testing, better code design and c++11 features.
- Uses std::complex instead of custom complex class
- Will focus of floating point instead of fixed-point modules
- Includes Chebyshev2 filter
- Bug fixes for odd order IIR filters
- Adding support for Bandpass and Bandstop designs for both IIR and FIR filters
Most of spuc was written many years ago before C++ compilers had good template support and was primarily written for fixed-point hardware design and simulation.
Currently there is some code for IIR Filter Design & Implementation
- Butterworth
- Chebyshev
- Inverse Chebyshev
- Elliptic
- Maximally flat FIR
- Remez Equiripple
- Raised Cosine FIR/Root Raised Cosine FIR
- Gaussian FIR
- Sinc FIR
- Cascaded Integrate Comb filters (or CIC filters)
- Notch filter
- Cut/Boost Filter
- Halfband/Subband IIR filters consisting of allpass sections
- Irrational resampling with Farrow & Lagrange based filters
To install via Homebrew
- brew tap audiofilter/spuce
- brew install spuce (or brew install -HEAD spuce for latest sources)
To install for Linux
The deb package is provided by the MyriadRF SDR Drivers PPA. The PPAs support the following Ubuntu releases:
- Trusty (14.04 LTS)
- Vivid (15.04)
- Wily (15.10)
Do the following to install on your Ubuntu system
- sudo add-apt-repository -y ppa:myriadrf/drivers
- sudo apt-get update
- sudo apt-get install libspuce-dev
For testing, python + matplotlib is used.
- Most of the test involve using python's matplotlib to show a frequency response of the filter, sometimes impulse responses are used
There are 4 QT apps for illustration purposes fir_plot, iir_plot, window_plot and other_plot
QT5 needed for test application
