72 class Filter :
public juce::IIRFilter
Header file for EffectBase class.
Header file for TextReader class.
Header file for JSON class.
Header file for the Keyframe class.
This abstract class is the base class, used by all effects in libopenshot.
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
void updateCoefficients(const double discrete_frequency, const double q_factor, const double gain, const int filter_type)
This class adds a equalization into the audio.
std::string PropertiesJSON(int64_t requested_frame) const override
void SetJson(const std::string value) override
Load JSON string into this object.
ParametricEQ()
Blank constructor, useful when using Json to load the effect properties.
std::shared_ptr< openshot::Frame > GetFrame(int64_t frame_number) override
This method is required for all derived classes of ClipBase, and returns a new openshot::Frame object...
std::string Json() const override
Generate JSON string of this object.
void updateFilters(int64_t frame_number, double sample_rate)
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
Json::Value JsonValue() const override
Generate Json::Value for this object.
openshot::FilterType filter_type
juce::OwnedArray< Filter > filters
This namespace is the default namespace for all code in the openshot library.
FilterType
This enumeration determines the filter type of ParametricEQ Effect.
