An IIR filter that can perform low, high, or band-pass filtering on an audio signal, with no thread-safety guarantees.
You should use this class if you need an IIR filter, and don't plan to call its member functions from multiple threads at once.

Returns the coefficients that this filter is using.
|
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.
|
noexcept |
Creates a copy of another filter.
|
noexceptinherited |
Clears the filter so that any incoming data passes through unchanged.
|
noexceptinherited |
Performs the filter operation on the given set of samples.
|
noexceptinherited |
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.
|
noexceptinherited |
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.

noexceptinherited |
Applies a set of coefficients to this filter.
