Pwede bang gamitin 2 usb mics at the same time? separate track each.
planning to buy kasi eh
It would be much better if you buy a single usb interface with 2 mic preamps and just add the mics to that. While you can use asio4all, remember that it adds it's own latency. One more thing, monitoring of separate usb mic streams is a problem, asio4all or not. Monitoring would be much simpler, and less stressful on your system if you just have one usb device in your system. Remember that usb devices typically send any return audio back to the originating device.
Asio4all is merely a wrapper that combines multiple WDM devices so that it appears as a single asio device. This is useful for DAW programs that use asio as their driver protocol, such as Cubase/Nuendo, Sonar, Live, Audition, etc. Where a DAW program uses WDM, there is no need for asio4all esp. if your audio devices have WDM drivers. WDM allows you to use multiple audio devices but at the sake of sync problems since each digital device each have their own clocks/crystals which provide the basis for their sample rates. Naturally, each device will have slight variances to their clocks unless they are synced digitally. Multiple usb devices are bound to have this problem since most of them do not have a way to sync their clocks unless they have some sort of digital input for syncing... most usb mics DO NOT have this.
One more thing, asio4all was originally developed so that onboard audio in most motherboards and laptops will appear as asio to DAW programs since practically all mobos and laptops DO NOT come with asio drivers. The developer lamented that fact that he could not use his inexpensive laptop with his copy of Cubase so he developed asio4all so he could wrap the laptop's WDM drivers in an asio shell, fooling Cubase to believe there was an asio device in the system. Naturally, there is a slight overhead involved because of the wrapper. Add to that the built-in latency of the laptop's WDM drivers then you have a system which does not truly report to you your overall system latency.
Personally, I would rather that I get a single audio device with bulletproof asio drivers since asio addresses your audio on the hardware level, unlike asio4all which is software. Asio drivers also report your true input/output latency more accurately than asio4all making for less ambiguity in compensating for overall system latency.
