TLV320AIC3256EVM-U: Mic to speaker

Part Number: TLV320AIC3256EVM-U


I  am  in charge of  a project of bluetooth headset with the function of  hearing aid. I choosed a Bluetooth chip as the Microprogrammed Control Unit (MCU) and TLV320AIC3256 as a digital signal processor of the audio. I want to use the Parametric EQ module(PEQ) of PurePath Studio as the hearing aid algorithm, but it seems the  PEQ has a very limited ability of compensation (0-12dB) for every frequency band. Is there  any other module which has a higher range of  compensation for every frequency band?
