filter out everything over a set frequency of my choice
im not to bothered about the sample rate
frequencies to exclude would be anything above 20hz and 30hz.
and would enable me to program what the maximum output would be e.g if "output" > 30 = mute or something like that! im not too sure.
i would also like to set the volume output according to the inputted frequency. i forgot to mention that
hi people, new to the forum and new to arduino programming so please bare with me.a bit of background:i make rotary subwoofers to produce ULF (ultra low frequencies) for audio systems. the problem is is that the unit that i make cannot accept certain frequencies because of its design.question:i would like to use the arduino (UNO) to accept an audio signal from a 3.5 jack, filter out everything over a set frequency of my choice and then output the filtered frequencies to an amplifier.any help would be greatly appeciated
i would also like be able to change these frequencies as well according to preference between 5 and 30hz.
No but Mr Shannon is.
