Detailed Description
Configuration for 3 Band Equalizer.
Configure the basic audio parameters (channels, bits_per_sample, sample_rate) and the equalizer settings. The frequency and gain parameters apply to all channels identically in the basic Equalizer3Bands class.
Frequency bands:
- Low band: DC to freq_low Hz
- Medium band: freq_low to freq_high Hz
- High band: freq_high to Nyquist frequency
Gain values should typically range from 0.0 to 2.0:
- 0.0 = complete attenuation (silence)
- 1.0 = no change (unity gain)
- 2.0 = 6dB boost
