Audio Mixing and Filtering

[siyal343]

Hello folks!

I am new here and I want some guidance.
I want to build a mixer board that can:

1. Mix 8 analog audio signals
2. Do some filtration
3. Output the mixed and filtered signal on a single line.

And I want these tasks to be accomplished digitally.

The board should be made from the scratch. I can not use ready-made DSP kits or development board.

Kindly guide me in this regard.
Thanking in anticipation.

The problem here is where are You getting the mixing and filtration chips from ….
Even if You find a manufacturer whit the specs You need, he will sell You only thousands of them.
Take a look at for example Pioneer DJ mixers. They use a chip inside with 100 legs which does everything digitally inside.


Buy a digital mixer, it is cheaper unless You are a rich person and can pay for R&D to a chip manufacturer.

Maaco this is Hazam's partner they are students doing this for a thesis project this was already discussed in another thread...construction of 8 channel live digital audio mixer

As covered in the other thread, you're undertaking a huge project here. I'd consider switching to analogue, but adding some neat digital features (digitally controlled pots are a thing - can you make a board that looks analogue, but can also be controlled by an iPad?)

I suspected that, although I note they did not say so at first.

A lot of reading would be the best place to start. How much reading would depend on how much they already know about digital audio (sampling, filtering etc.) and mixed-signal PCB design.
