Vinjey Parametric Equalizer (VPEQ) is VINJEY's implementation of Parametric Equalizer. The audio PCM samples from decoder output are passed through VPEQ at pre-defined sampling rate with user selected Quality or Bandwidth, center frequency, Equalizer number of bands, and user gain (boost or cut) per band in real-time to ensure enhanced quality with post processing algorithms. VPEQ algorithm has been developed from scratch keeping in mind MIPS and memory requirements of resource constrained embedded devices .
(user defined Quality / Bandwitdth, Center frequency, Number of Equalizer bands & gain = +12 dB to -12 dB)
