Hi All,

I'd like to be able to use my video camera (which is actually my Galaxy S7 phone) to record some videos, but the catch is I'd like to use TWO external microphones when I do it...

Wait there's more!

Both microphones are USB.

So essentially I need a piece of equipment that allows two USB mic inputs and mixes them down to a 3.5mm headphone jack sized output for use with the phone...

Does this exist?!

Thanks!
 
I have never heard of such a thing myself. I am not even sure it is possible to record two USB mics at the same time with anything. Maybe a MAC PC but not worth it IMO.

You may be better getting something like THIS and then sync the video to the audio with a video editor.
 
Usb mics are actually a mic and interface in one. The problem is, there is usually no way to use two interfaces at the same time.

Now you want to plug it into a phone? Not likely.
 
Two USB mics >> (USB in on each) two computers (audio out from each)>> external audio mixer >> phone
 
It is the USB mics that are gumming up the works. They are really meant to be a singular source. They don't work with other mics of any kind. As soon as you need to do more than plug a single one into a computer, it becomes useless. There is always much more flexibility with normal mics and interfaces.

USB mics convert the analog audio to digital and send it up the USB cable. You would need something that powers the mic and converts the audio back to analog. One computer for each mic would do it though I doubt that suits your needs. A separate recorder is the way to go.
 
+1 to all before.
If you happen to have a mac you can do MJBs solution but with only one computer.

Is it essential to record audio to the phone? It means a lot of restrictions.
A handheld recorder with 2 external inputs, or a USB interface and laptop would be much better in terms of editing, processing, flexibility and quality.
 
USB mics are usually good for a very limited range of applications, that's why they tend to get dismissed. They can be very good quality - but all sorts of compromises mean USB is a poor connection method. In short - USB mics are very bad at recording quiet sound sources. They are also very bad at recording very loud sound sources. They often mean the types of mic elements are more limited. Some mics use quite large diaphragms inside, and these need a polarising voltage - USB had just 5V available, meaning the mic has to have additional circuitry to provide the higher voltage it needs to function. Extra cost, and as a result, most USB mics have small diaphragm electret capsules that are permanently polarised. They can be fine, of course, but rarely that 'smooth'. The problem people have mentioned here is the one that means two is a rare thing. Especially as two indicates stereo for many people - and stereo recording is very timing sensitive, so two USB inputs to one bit of software, even if you could make that work, would be somewhat loose, timing wise, as I don't think time aligned parallel processing is possible via USB. So, being general - recording video to a phone is er, limited in quality and facilities. Recording to this device by using 2 X USB going to the 3.5mm input is going to be, er, limited in quality and facilities - so all in all I have to ask why? You are making loads of compromises - in my view, too many. Of course, you could be recording in an aircraft, where camera size is critical, and already have two small USB microphones you can attach the headsets of the two people in it. You might have very little budget left, and are hoping there's a simple system that will let this work. Sounds simple. It isn't!
 
It's like building a car out of two bicycles and a lawnmower.
