How to make an audio processor on fpga?

Tell me, please, how best to make an audio processor on fpga. There are enough articles on the Internet, but I'm more interested in exactly how to make a 3.5 jack (and 6 mm jack) input and output, and articles come across about the actual flow of an existing audio input.
The most stupid thing is to use an ADC, take readings at a frequency of 44KHz and run it through the board and put a DAC with an amplifier at the output. But there is a feeling that in such a simple version it will not work. I am at a loss, I did not find ready-made solutions (the ADC-DAC interface is not usb, but which will produce 24-bit values ​​\u200b\u200bat the output and input).
Tell me, in which direction should I dig?

Answer 1

a = 0
b = '0'

or

a = false
b = '0'

or

a = 0
b = {
  valueOf: () => 0,
}

or

a = ''
b = {
  toString: () => '',
}
