    I want to use an external mic with the EVO LTE when shooting video. Is this possible?

    I've played with shooting a few car videos, but the audio was horrible. Do I need a specific camera app and or some adapters?

    the headset port has 3 rings--L/R and mic.
    you can get a custom male jack made that will access the mics input.

    you could make this yourself if you are handy or scour the internet using search strings to bring up some possibilities. there has to be something out there.

    you do not need a specific app. any app that supports high resolution audio recording will work.

    for the built in mic on the phone, you can use noise a mic sock style material that can adhere over the mics opening to break down the wind noise you get. ive such a mic sock on my Digital photo camera that shoots 1080p and has stereo mics.

    Thank you for the info. I am pretty good with making wiring, etc. I'll see what I can dig up.

    So the stock video app should record using an external mic if it is plugged in? I'll be picking up some parts tonight for the mic, guess I'll find out if no one posts. haha

    I'll look into making a wind noise sock too, wouldnt hurt.

    i dont think the stock app will record audio externally though. :( there are no doubt apps in the store that can do this, but more then likely the stock app will not. apologies for the confusion...

    I bought a splitter ($7.65 on Amazon)to access the headphone/mic input on my HTC Thunderbolt.
    An Audio Technica ATR6550 shotgun mike works fine with the built-in camcorder software. Note that the impedence on this is 2200 ohms.
    I have half a dozen other microphones, and NONE of them work (some have an impedence of around 1000 ohms, so maybe this is the problem).
    So, here is what I know:
    1. This is possible (at least with the atr6550).
    2. The necessary splitter (i.e. splits input jack into mic + earphone connectors) is not expensive, and there seems no reason to use any different connector.
    3. I have half a dozen other mics and NONE of them works.
    4. I don't know if the incompatibility of the others is an impedence problem or a voltage / current problem, and don't know how to find out.
    Here is the splitter info:

    Did you ever find an answer to this? I'm currently looking into the same thing.
