  • Method Details

    • bw

      public void bw(float bw)
      Sets the bandwidth of this BandPass filter.
      Parameters:
      bw - the filter bandwidth in Hertz
      See Also:
      • BandPass#res()

    • res

      public void res(float q)
      Sets a fixed Q factor for this filter. If you want to specify a fixed bandwidth for this bandpass filter (in Hertz) that is maintained even as the center frequency of the filter changes, use bw(float) instead.
      Overrides:
      res in class Filter<FilterBandPass>
      Parameters:
      q - the desired Q factor, a value between 0.1 and 10
      See Also:
      • BandPass#bw()

    • freq

      public void freq(float freq)
      Sets the center frequency of the filter.
      Overrides:
      freq in class Filter<FilterBandPass>
      Parameters:
      freq - the center frequency in Hertz

    • process

      public void process(SoundObject input, float freq, float bw)
      Start applying this bandpass filter to an input signal.
      Overrides:
      process in class Filter<FilterBandPass>
      Parameters:
      input - the sound source to filter
      freq - the center frequency in Hertz
      bw - the filter bandwidth in Hertz

    • set

      public void set(float freq, float bw)
      Sets frequency and bandwidth of the filter with one method.
      Overrides:
      set in class Filter<FilterBandPass>
      Parameters:
      freq - the center frequency in Hertz
      bw - the filter bandwidth in Hertz
