Detailed Description

A base class for filters with multiple channels.

It exposes an interface for different filter types which have common methods for setting their parameters, initialisation etc.

Member Function Documentation

virtual void processSamples ( AudioSampleBuffer &  buffer,
int  startSample,
int  numSamples 
pure virtual

Implement the filter algorithm here.

virtual void reset ( )
pure virtual

Overwrite this method and reset all internal variables like previous values etc. This will be called when a new voice is started to prevent clicks in the processing.

void setFrequency ( double  newFrequency)

Set the new frequency (real values from 20Hz to Fs/2).

void setNumChannels ( int  newNumChannels)

Sets the amount of channels.

void setQ ( double  newQ)

Set the resonance.

void setSampleRate ( double  newSampleRate)

Sets the samplerate. This will be automatically called whenever the sample rate changes.

void setType ( int  newType)

Set the filter type. The type is just a plain integer so it's up to your filter implementation to decide what is happening with the value.

virtual void updateCoefficients ( )
pure virtual

this will be called whenever the frequency, q, or samplerate changes.
