◆ IIRFilter() [1/2]
juce::IIRFilter::IIRFilter |
( |
| ) |
|
|
noexcept |
Creates a filter.
Initially the filter is inactive, so will have no effect on samples that you process with it. Use the setCoefficients() method to turn it into the type of filter needed.

◆ makeInactive()
void juce::IIRFilter::makeInactive |
( |

|
|
noexcept |
Clears the filter so that any incoming data passes through unchanged.

◆ setCoefficients()
void juce::IIRFilter::setCoefficients |

const IIRCoefficients & |

|
|
noexcept |
◆ getCoefficients()
Returns the coefficients that this filter is using.
Definition at line 186 of file juce_IIRFilter.h.
◆ reset()
void juce::IIRFilter::reset |
( |
| ) |
|
|
noexcept |
Resets the filter's processing pipeline, ready to start a new stream of data.
Note that this clears the processing state, but the type of filter and its coefficients aren't changed. To put a filter into an inactive state, use the makeInactive() method.

◆ processSamples()
void juce::IIRFilter::processSamples |
( |
float * |
samples, |
|
|
int |
numSamples |
|
) |
| |
|
noexcept |
Performs the filter operation on the given set of samples.

◆ processSingleSampleRaw()
float juce::IIRFilter::processSingleSampleRaw |
( |
float |
sample | ) |
|
|
noexcept |
Processes a single sample, without any locking or checking.
Use this if you need fast processing of a single value, but be aware that this isn't thread-safe in the way that processSamples() is.
