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.
