Detailed Description

An IIR filter that can perform low, high, or band-pass filtering on an audio signal, and which attempts to implement basic thread-safety.

This class synchronises calls to some of its member functions, making it safe (although not necessarily real-time-safe) to reset the filter or apply new coefficients while the filter is processing on another thread. In most cases this style of internal locking should not be used, and you should attempt to provide thread-safety at a higher level in your program. If you can guarantee that calls to the filter will be synchronised externally, you could consider switching to SingleThreadedIIRFilter instead.

Member Function Documentation

◆ IIRFilterBase() [1/2]

juce::IIRFilterBase< Mutex >::IIRFilterBase ( )
defaultnoexcept

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.

◆ IIRFilterBase() [2/2]

juce::IIRFilterBase< Mutex >::IIRFilterBase ( const IIRFilterBase & other)
noexcept

Creates a copy of another filter.
