An IIR filter that can perform low, high, or band-pass filtering on an audio signal.
|
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 |
Destructor.
|
inlinenoexcept |
Returns the coefficients that this filter is using.
|
noexcept |
Clears the filter so that any incoming data passes through unchanged.
|
noexcept |
Performs the filter operation on the given set of samples.
|
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.
|
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.
|
noexcept |
Applies a set of coefficients to this filter.
