Honest questions: how many "frames per second" is a standard microphone? What exactly is a "frame" of audio?
- andars 11y agoTypical sampling rates for microphones are 44.1, 48, or 96 kHz. A "frame" of audio would just be a sample taken from the microphone
- WiseWeasel 11y ago44.1 kHz (CD quality audio) is 44,100 samples per second, though professional recording equipment typically supports up to 96 kHz sample rates. Note that for the more common analog microphones, the microphone itself doesn't determine the sample rates; it's the digital sampler to which it's connected.
- teej 11y agoThis makes sense, thank you!
- raverbashing 11y ago"the microphone itself doesn't determine the sample rates" True, but it has a response curve, and I assume most don't respond as well to >20kHz frequency (or even less)
- StavrosK 11y agoKeep in mind that, even with 120 fps of video, you can pretty much only reproduce frequencies of up to 60 Hz. I guess they do some more modeling to make the sound more intelligible, though.
