I am just going to assume you don’t know much about audio interfaces and AD/DA’s in general otherwise you’d probably realise that is a bit daft.given they all use different firmware and components so how could ASIO4ALL possibly know how to get the best spec for such a varying amount of interfaces and their drivers…rhetorical question(it can’t as you get a fixed
minimum and maximum amountt of latency for the given samplerate regardless of the card)
I know from experience that the only situation ASIO4ALL makes sense is when you are dealing with internal soundcards not spec’d for professional audio,because they bypass any dodgy processing that they sometimes have and also can achieve "passable"latency,but you’d find them extremely lacking with e.g an RME Babyface or Fireface and its drivers(which are the best of the best in terms of latency at least for Windows and would out perform ASIO4ALL by a large margin)
