With this If I capture all audio signals, do I need to do any clock synchronization ? assuming all will be captured using single clock.<br>

You use a sound interface with more than 5 audio stereo inputs. Nothing<br>
special is required to work with those, and there is a whole slew of<br>
them. Personally, I am using a Mackie Onyx 1640 mixer with Firewire<br>
card that has 8 mono and 4 stereo channels and delivers 18 channels (2<br>
additional channels for the Main Mix). But of course there are other<br>
devices delivering similar functionality.<br>
<br>
It's also common to have sound interfaces with 8 analog inputs of their<br>
own able to synchronize on an ADAT source where you employ another<br>
8-channel A/D converter in order to get 16 (or 24 channels) of result.<br>
<br>
For more comparable results, there are interfaces like an RME Digiface<br>
which accept several A/D converters (which you need to set up such that<br>
they synchronize to a common clock).<br>
<br>
Of course, the solutions with additional A/D converters are not exactly<br>
cheap, so a multichannel mixer with computer interface, though quite<br>
bulky, might be the most affordable option once you cross the "8 analog<br>
inputs" threshold: few dedicated sound interfaces have more than that.<br>
