What's the best way to record a video with high quality audio? Specifically, this is for a presentation where a microphone could be placed by the speaker. I know that an app that records with the right codec is necessary, but what about the microphone?

I'd prefer to use a USB mic but, even though Android 3.1+ supports USB host mode, it doesn't appear that this is easy to accomplish. What about a 3.5mm microphone - would that yield acceptable results, or would it be better to stick with the built-in microphone? Are any of the video-recording apps capable of handling the microphone?

Does your device have a mic jack? – Matthew Read♦ Feb 10 '12 at 17:48
Yes and no... I have a few test devices, let's say the Droid 1, which should work with a wired handsfree device. I'll need to track down a splitter to use it with a standard 3.5mm microphone. If I'm going the USB Host route, I'll use a Xoom or put a beta of Cyanogenmod9 (with ICS) onto the Droid 1. There seem to be problems with using line-in audio for video recording, from what I've seen. I'm still testing. – ProjectJourneyman Feb 11 '12 at 4:37

It's not a usb mic, but i have found a solution for external mic via 3.5 mm jack... Look at my answer in this thread here: How do i use a external microphone with my Galaxy Nexus?

Thanks, I ordered an TRRS cable, and will check out how that works. My USB mic would be better sound, but this may yield acceptable results. – ProjectJourneyman Feb 16 '12 at 7:32
it does for me :) – dev0 Feb 16 '12 at 14:43
i have two wireless microphones (for song etc.) on my galaxy Nexus now :) – dev0 Feb 16 '12 at 14:43
TRRS cable works for a simple microphone (too bad I don't have any good 3.5mm microphones right now). I used TapeMachine lite to test, since it shows the waveform. Red connector for mic. Unfortunately, I haven't had any luck with using it for video yet, even with LG Camera. – ProjectJourneyman Feb 21 '12 at 15:32
You need to find the right poles... It works for me after the right poles.. I can take a picture later if you want... – dev0 Feb 21 '12 at 15:41

I use the Irig Pre interface (30 euro / 30-40 US dollars) to connect any XLR mic to my HTC wildfire. In flightmode I can make good 48khz mono WAV recordings with the Taperecorder app.

When I switch flightmode off there sometimes are some ticks and clicks.

Afterwards you cann edit your recording and convert it into MP3 files.

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: StarTech.com MUYHSMFF 3.5mm 4-Pin to 2x 3-Pin 3.5mm Headset Splitter Adapter - M/F Sold by: Amazon.com LLC
