Truly hands-free voice recording over bluetooth I know that there are lots of "voice recorder" apps out there.  Some of them will let you record using your bluetooth headset instead of the built-in mic.   However, all the ones I have looked at say things like "tap the button to start recording".  This defeats the purpose of what I am trying to do, which is to record thoughts I have while I am out and about walking, biking, driving, etc. when I can reach up and hit a button on my bluetooth phone, but I am not able to stop, pull my phone out of wherever I have it stashed, take off my gloves so I can touch the screen, power up the device, enter my lock code, jump to the record app if needed, and tap to start recording.  By the time I have done that I have lost my train of thought, and wasted a lot of time.

Voice activated recording is probably not going to work, because, even though my headset has some degree of wind cancellation, there is a lot of ambient noise from time to time.

I can use voice commands, which is still a bit of a pain but at least keeps me mostly hands free, that is, I can tap the button on my headset, say "activate" and my headset will connect to the phone and bring up voice commands.  However, I am not sure what I would do next.  The commands offered are things like "Go To &lt;&lt; Shortcut >>", and "Check &lt;&lt; Item >>" - these are the only two that seems remotely related to what I am trying to do.  I assume that maybe if I said something like "Go To Voice Recorder" it might open up the voice recorder, but I couldn't get it to work and am not sure what it expects for &lt;&lt; Shortcut >>.  Even then, assuming that part would work, I would need to have some way of telling the app to start recording, for instance, if the shortcut was not just the app but a full-blown intent.  I am not sure how I would set that up.  There is also the question of how to stop it, but hopefully hitting the headset button again would work as that already as a similar function while on a phone call.

Am I on the right track here?  Is there some kind of app that will help me out here?  One thing I don't understand is, does the app have to explicitly support bluetooth audio for this to work?  I would think the OS (Android) would abstract away the input source, yet some apps explicitly claim Bluetooth support (even going so far as to only support it in the for-pay version) while others don't say anything about it.
The Google Now option for Note to Self might work for you... It doesn't do a voice memo, but it will let you leave notes to yourself.
