  1. Audio processing

    Yes band pass... The reason is I want to use three or four band pass filters , each of them will pass some respective frequency band (input being an audio range)... The idea is to provide the facility of boasting or attenuating a particular band so I thought band pass would be the best option for that.......... I just want band pass filter not FIR one...........
  2. Audio processing

    thank you for the reply sir ....... Could you guide how can I make band pass filter that takes audio data and output as audio? I would like to know the vhdl approach for band pass filter because I want to use it in my project. Could be more of help if it is behavioral modelling..............................
  3. Audio processing

    yes if I use 48kHz, what does couple of block averages mean? How will I write a vhdl code for it? Because right now at this point I don't want to use the filters..... thank you for the help sir, would be grateful if you could help me make this stuff work.
  4. Audio processing

    I am working with nexys 4 ddr board... I am using on board microphone and audio jack with task of giving audio at the mic and hearing through speakers or headphones at the jack....... The nexys datasheet says there is a need of three signals... mic clk, lrsel and data output... Now am I suppose to directly provide the name of the output pin in the xdc file in pwn audio section or there is some processing to be done? the data output is H5 but where is it routed?... and on the other side audio jack needs pdm/ pwm input which is the same form that mic gives....so just help me with the logic... THANK YOU
  5. thanks a lot ..............
  6. https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-dma-audio-demo/start this is the link............ Explain me why they have used usb-uart bridge apart form the reason of serial communication? if even it is the only reason plz explain me in detail...............
  7. thanks a lot ................
  8. Why the concept of fft has been used.. Plz explain....
