Hi all, Im currently working on a project that involves recording audio using electret condensers and the arduino. The microphones i will be using are these: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=102-1728-ND Currently, my knowledge extends primarily to the software/progr…

[image] Electret microphone An electret microphone is a type of electrostatic capacitor-based microphone, which eliminates the need for a polarizing power supply by using a permanently charged material. An electret is a stable dielectric material with a permanently embedded static electri…

Hi, thanks for the reply! Once I have the microphones wired correctly, I will pass the signal through an op-amp to make it usable. Ultimately, my plan is to record 3-4 audio streams simultaneously. I know the arduino's limited bandwith may make things difficult, however I believe any such issues ca…

"Also, does the arduino output DC or AC (actually, this is probably on the arduino data sheet, Ill have to check that)." That is a problem in that microprocessors only handle positive voltages from 0 to +5vdc. So after amplifying a audio signal such that it's peak to peak voltage is 5volt, it has t…

"Also I think you will find that the Arduino will not be able to sample a audio signal and be able to recover any useful data, it's just doesn't have the horsepower to do it directly. " I was wondering about this... If the arduino is incapable of sampling with enough detail, what else could i use, …

Oh, I forgot to mention (which is probably pretty important) that my first project really should only require an accurate representation of the intensity of the sound received from the mic, not necessarily a fully constructed waveform... However, in the future, I may wish to analyze entire waveform…
