A nice circuit here but you have to build it:

If the url is too long, google for "single supply mic amp" and look for
Op Amp applications handbook - Google Books Result

Single-Ended, Single-Supply High-Impedance Mic Preamp.

hei,
I have a question not directly related to PD. But since this list is my
favorite audio and device-hackers list I ask it here.
(maybe you can refer me to a nice list about topics like that.)
I have some microphones - a very cheap small microphone and a stereo
mic- they work fine to record into my mp3-player.
But I want to record directly with those mics into pd trough my
soundcard (audio kontrol 1). And it's not amplified.
How can i build a hardware amplifier for those mics- or buy something
like that? any suggestions?
(I prefer to buy something- since I have to hack allready a lot of other
devices...)
thanks for any hints
cheers
