Here is the situation, I have got an USB Audio Card recently. And I want to implement some cool stuff based on the card. But the latency became the most serious problem.
So I want to write a filter driver to capture the microphone in PCM format. And next step, I want to send it via TCP/IP.
I want to know:
1, As far as I know, USBAudio.sys is also a filter driver, Is that still possible to apply another filter upon it?
2, If it was possible, How could I start?
3, Just capture the PCM format data will also be OK.
