Want to test my monitors for flatness, but what am I missing?
I found this freeware frequency and spectrum analyzer:
http://www.sarand.com/prd/winsingad/winsingad.html I've got a pretty flat mic. But what do I play through the monitors? Do I need some type of tone generator to step through the frequencies and see how it looks on the analyzer? |

You need a pink noise generator and a Real Time Analizer if I'm understanding your question right. Adobe Audition has a noise generator built in. I belive most other audio editing programs will also, but I'm just assuming there.

Dave,
You can get a 30-day trial of a much more sophisticated ($600) system, that includes everything you need (including online tutorials here: http://www.ymec.com/products/dssf3e/ I've used it to analyze the inputs of my cams and the DXA-8 They also offer a $24 subset (their Real Time Analyzer) that includes a tone generator with a sweep function, an oscilloscope and several other functions.

What really is pink noise? Just by playing this
pink noise, the analyzer can tell how flat my monitors are, assuming my mic is flat? |

Hopefully that freeware program I found has the
pink noise in it. So, the pink noise runs through all the different frequencies? Like, steps up from low tones to the high pitched tones? |

Pink noise contains all the tones at once.
You can also try a test sound which uses sine wave tones which change from low to high. I believe this will give you a different result than pink noise. |
