For more information, see the [API documentation](https://surge-synthesizer.github.io/sst-docs/docs/sst-filters).

## Usage

`sst-filters` is a header-only library, so it is possible to use the library

simply by adding `include/` to your header search paths, and writing

`#include ` somewhere in your source code. However, it is

recommended to use the provided CMake configuration.

```cmake

add_subdirectory(path/to/sst-filters)

target_link_libraries(My-Killer-App PUBLIC  sst-filters)

```

**Note: the sst-filters library uses raw SSE SIMD intrinsics. If you

are planning to use this library in a context that may not support SSE

intrisics, it is recommended to also link with

[simde](https://github.com/simd-everywhere/simde).**

## Building Unit Tests

To build and run the sst-filters unit tests:

```bash

cmake -Bbuild

cmake --build build

./build/test-binary/sst-filters-tests

```

## Building Examples

```bash

cmake -Bbuild -DSST_FILTERS_BUILD_EXAMPLES=ON

cmake --build build

```

Example binaries will be located in `build/example-binaries/`.
