A REAL mic is a very low output device, a device on the same level as a phono cartridge in level so needs a preamplifying stage to "up' the signal to a level usable into a line level input,Because this gain is so high and will be cascading into another gain stage (the line level gain stage) any noise WILL be amplified along with the signal by a factor of X Gain of the line stage and so places a serious demand on the mic preamp.
Straight into a computer mic input is usually not a great idea even IF the gain is high enough due to that being targeted to a dialog mic only and not a music mic input.It will be noisy,it will have a seriously crappy overload margin and the response will not be what you need for anything other than dictation unless your freind has a sound card that is designed from the start to be used for recording.Better to front the line inputs with a preamp.a preamp that YOU control so the levels never get to "hot" into the sound card and.
If you
must use the mic input of the sound card straight in then one of the Lavelier "tie clip" condenser mics can be used.available from all the usual suspects (AT,EV,SHURE,Sennheiser,AKG.Etc.) can range from "vocal only" all the way to true high end audio recording but being a small diaphragm mic capsule don't expect to have the ability to record high level music.acoustic guitar,vocals,maybe some brass or woodwinds....
Because it is an electret and meant for quick and dirty "plug 'er in and hit record" dity most have built in a jfet preamp stage/mic capsule bias supply?DC Blocking caps so will plug directly into any low sensitivity mic input such as a computer sound card or portable recorder.There are a few very expensive models ready for prime time but most no so accept the limitations and record to strengths only.

What is the KSC75 of mic preamps (without phantom power)?
Naturally I've also asked this question at the studio forum, but there's no such consensus like in the mic case.What I've got was 30 opinions and a flame war. |
that surprises considering any knucklhead knows there IS NO one size fits all when it comes to mic preamps but targeted use results only.
If it is the best for the least then the Rolls lineup is hard to beat with a stick.Not the last word in preamps but usable just the same.a step up in class would be the Rane MS-1B which is a nice design having enough options to be totally usable.

and in kit form this is a killer for the price if you use upgraded parts on the initial build :

All the above are what are considered "clean" mic stages.That is no intenional colorations are added to the basic sound of the mic so unless you have access to EQ in the mixer you would use the mic choice or mic proximity effect to dial in the "tone" you are looking for.
This type of preamp is more "overall performance" oriented than target specific to an solo voice or instrument where you would use a particular mic stage to get the general tone you are looking for.The misconception many have is that studio recording gear has the same requirements as home playback gear-it does no.
In the home any distortions or deviations from nuetral are to be avoided like a contageous disease but in the studio these things are required if you are to ge the exact sound you are looking for in an indivuidual performance be it instrumental or vocal so I guess the answer is there is no answer in general only answers to what is the deired goal.
BTW-here is a very good read on the topic in "any man" language :
