For example, te ESI Juli@ soundcard. You can get a latency of < 100 ms, easy.
i search on that but i cant find any prices of sales point in my country ?
Any 192kHz soundcard with ASIO support will do the job, PCI, PCI-E, USB. Avoid Creative and Asus soundcards. You will maybe not use 192kHz because you are not using MPX output, but it's good to have it for future.
Also always check your buffer in ST (standalone normal/FM output) maybe it's at default 1 second. You can easy put it way lower depending on your soundcard and cpu.
