49 / 156 page  ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 37 Rev. 0.93 7.12. SounzReal Sound Effect The Realtek ’s SounzReal sound effect is composed of: OmniHeadphone OmniSound Dipole Speaker MP3 Enhancement BassBack BassBoost 7.13. Equalizer Block The equalizer block cascades 7 bands of equalizer to tailor the frequency characteristics of embedded speaker system according to user preferences and to emulate environment sound. The 7 bands equalizer includes two high pass filter, four band pass filter and one low pass filter. One high pass filter cascaded in the front end is used to drop low frequency tone, The tone has a large amplitude and may damage a mini speaker. The high pass filter can be used to adjust Treble strength with gain control. One low pass filter with gain control can adjust the Bass strength. Four bands of bi-quad band pass filters are used to emulate environment sound s, e.g., ‘Pub’, ‘Live’, ‘Rock’,… etc.. The gain, center frequency and bandwidth of each filter are all programmable. 7.14. Dynamic Wind Noise Reduction Filter The wind filter is implemented by a high pass filter equalizer. The wind filter is mainly for ADC recording used. The cut-off freqnecy of wind filter is programmable and is varied accroding to different sample rate. The filter is used to remove DC offset at normal condition, and to remove wind noise at application mode. The wind filter builds in auto detection scheme. When wind noise is higher than the threshold, the filter will be turn-on. When wind noise is lower than the threshold, the filter will be turn-off. This scheme will keep recording quality and also remove wind noise. Wind filter setting procedure: Step1: Disable wind noise detection if needed – PR-6C[15] Step2: Disable wind filter – MX-D3[15] Step3: Select target sample rate – MX-D3[14:12] and MX-D3[10:8] Step3: Fine tune wind filter Fc – PR-6E[11:6] Step4: Enable wind filter – MX-D3[15] Step5: Enable wind noise detection if needed – MX-D3[15] |
