USB port mic on the 50D?
« on: June 03, 2013, 09:58:34 AM »
Hey, Just following somewhat on the train of thought from this topic:;boardseen#new

It seems it's possible to transfer data to/from the camera via USB port in non ordinary ways.

Soooo, being a new found 50D owner, the natural conclusion...

The gopro camera has a cable that converts its mini USB port into a mic jack:

If using a battery powered 3.5mm mic, would it be possible to stream the info from it into the camera in a way that would be useful to gain audio/wav file record? Or even just a very basic audio data or some sort that could be comprehended in a way to make it good enough to synch an external recorder with.

I realise the 50D has the same digic processor as other cameras, but does this handle the audio component too, or just image processing? I think I recall someone saying something about seperate audio chips for various cameras.

Obviously the 50D has the most to gain from this possibility, but it could also be handy for other cameras having a second audio input/output if that helps with monitoring or whatever perhaps...

Yes, I have checked the "Dont ask for this/not possible" thread first... If this gets added, so be it :)

If it seems somewhat possible-ish I can find the pin outs for the gopro cable etc if need be.

Just thinking about this some more, it seems obvious that the gopro would have some onboard sound hardware to interpret the signal etc. So a straight mic jack to USB plug wouldnt help if there's nowhere to send the analogue signal on the 50D.

However I'd imagine a regular USB mic has this onboard, and just uses the USB port to stream digital data and send/recieve requests like stop/start.

Something like this perhaps, with an adaptor to mini usb:

Although it needs drivers installed to work with windows, so I've no idea how/if there would be any useful way to transfer data to/from a camera with it where things are a bit more limited.

Or alternatively, the Blue Yeti mic doesnt need any drivers installed to make it run... And I've got one of these already.

Might see what else I can find out about it.

The 50d was designed to have video. Canon just dropped it out on the last minute, because it was smarter to introduce it on the 5d2. 50d even has a mic socket for where the holes of a mic would be if you open it up.
Although very unlikely the idea of a USB mic directly to the 50d sounds awesome.
USB condensers require too much power I think. No idea but I'm not sure the 50d USB port could power anything at all. So that leaves out most to the USB mics out there.
