i would like to write a software of acoustic recognition in assembly language that will work under homemade 64bits 100% assembly OS , i can not consequently use call system or any known API(even if i could i would not). My board is MSI Z170-A PRO that integrates the component ALC892 here its datasheet http://www.hardwaresecrets.com/datas...aSheet_1.3.pdf
. Is targeted first an anti aliasing filter before sampling and application of Fourier tranformation on this last. Is anti aliasing filter existing in sound card, microphone or anywhere in my motherboard ? Sampling i think i will not have any problem about it. A people who known well electrocnics said me there is everytime a component specificaly intented for Fourier transformation in sound card, is it correct ? If yes, under what calling could i find it in datasheet ? For the rest i have a clear vision of how to proceed, i only need information about these three points.
thank you in advance.
