Need Built-in Microphone Specifications

Apple doesn't publish those specifications. It's reasonable to assume the mic is omnidirectional, however, with a frequency range typical of small mics - 50-15,000 cycles.

BTW, if you have a Core 2 Duo iMac, then it's an Intel machine, not a G5 as indicated in your configuration profile. No G5 iMacs were made after 2005.

Hi idman

See the > [Audio Product-Specific Details|http://developer.apple.com/legacy/mac/library/documentation/Hardware/Co nceptual/HWTech Audio/Articles/Audioimplementation.html]

+*Internal Microphone*+
+The internal microphone operates independently from all other audio input ports and is always available. The internal microphone supports recording at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. Audio recorded from the microphone is presented as a stereo data stream with the same data appearing on both the left and right channels. The microphone gain can be adjusted from -16 dB to 30 dB.+

Mein has failed too. 😟
The same as hard drive and GPU.

Again, I'm guessing condenser because these are generally small and provide better pick-up from a distance. But, again, it's simply a guess.
