Design biquad peaking equalizer filter and perform filtering. Similar to SoX implementation.
functional_equalizer_biquad( waveform, sample_rate, center_freq, gain, Q = 0.707 )
(Tensor): audio waveform of dimension of
(int): sampling rate of the waveform, e.g. 44100 (Hz)
(float): filter's central frequency
(float): desired gain at the boost (or attenuation) in dB
