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 |
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 |
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.
