    Wasn't sure whether this should go here or in "Accessories," but I thought more people might see it here:

    I am a college professor who is thinking about podcasting my lectures next semester. It occurred to me that I might be able to use my new Treo 650 to record my lectures. I know the Treo can record voice memos, but I'm not sure what to use for a microphone. So:

    (a) How's the voice recording quality on the Treo? Will the Treo balk at me trying to record a 75 minute lecture to an SD card?

    (b) Does anybody know of a good external microphone to use? Ideally, I'd love a lapel mic that I could plug into the Treo and record directly to the Treo. Or I suppose even a wireless mic would work. Could I use a BT headset to record to the Treo?

    Thanks for your help.

    As far as I know, only commercial voice recording software can record directly to the SD card in real-time. Here's one worth trying:

    Fortunately the memory requirements of compressed voice are relatively modest if a good codec is used. If you use a codec designed for speech (not for music), then 8kbps is sufficient. This means that your 75 minute lecture will only consume about 5MB.

    I have little experience with respect to recording voice and using mics on the Treo, but I have a fair amount of experience with (desktop) voice recognition software and mics.

    I think that a lavalier mic (aka a lapel mic) is a good solution for you, although you might also consider a traditional wired computer headset. Using bluetooth will leave you very frustrated with regard to voice quality.

    I recommend talking to the folks at emicrophones.com. I have no affiliation with them, etc., but have used them for voice recognition microphones.

    Don't forget to use the Seidio 2.5->3.5mm adapter, not the Palm one.

    HTH...

    Thanks, Jae. Sorry for the noob questions, but I just want to try and make sure I have this correct.

    Can the headphone jack at the bottom of the Treo be used as an "audio in" jack? If I plug a microphone into that jack, will I be able to record to the Treo?

    Sorry for my slow response. I used to have a lot of mics around for voice recognition, but the few that I have now are rarely tested. I was finally able to find one that worked with my PC, but I wasn't able to get it to work with the 3.5mm Seidio adapter+Treo650. I won't say categorically that it doesn't work, but I wasn't able to make it work.

    Here are some other options which plug directly into the 2.5mm jack, and should work (after all, the microphone/headset provided by Palm works):

    I suggest calling the latter company to see when they'll have the lavalier mic in stock.

    HTH...
