音频均衡器，Matlab Simulink模块，实现参数可调的音频均衡器，5段均衡-Audio equalizer, Matlab Simulink module, adjustable parameters to achieve the audio equalizer, 5 balanced

The equalizer has a number of bands, and each band has a frequency, and a volume. With Phonon s API, this is modeled such that each band is one Phonon::EffectParameter, where Phonon::EffectParameter::id() is the band num
