DSP Tool Box

Summary

The dsp-tool-box contains very basic DSP algorithms. Algorithms can operate on one sample at a time. Like this an update of a parameter can be done any time while processing.

Building the project

Execute the following commands on cli.

git clone https://www.github.com/hansen-audio/dsp-tool-box.git
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug ../dsp-tool-box
cmake --build .

CMake Generators

CMake geneartors for all platforms.

• Linux: cmake -DCMAKE_BUILD_TYPE=[Debug|Release] ...
• macOS: cmake -GXcode ...
• Windows 10: cmake -G"Visual Studio 16 2019" -A x64 ...

Algorithms

Currently the following algorithms are available:

• one pole filter
• modulation phase

Using the algorithms

All algorithm classes in this library contain a context and static methods in order to modify the context. Like this the data and the algorithm are separated and allow a usage in a multithreaded environment.

Setting parameters of the context

Use the create method of the phase class in order to get a valid context. Afterwards use the static methods like set_tempo to modify the context.

auto phase_context = ha::dtb::modulation::phase::create();
ha::dtb::modulation::phase::set_tempo(phase_context, 120.);

Processing a module

After setting all parameters of the context the phase can advance a value by the specified amount of samples, in this case 32. The overflow boolean flags an overflow.

real value = 0;
bool overflow = ha::dtb::modulation::phase::advance(context const& cx, mut_real& value, 32);
