Have you looked at Audacity?

It is a very nice package and it is free.

I have been using it to analyze my lightning and thunder data.

I too am searching for similar audio analysis capabilities for low-noise testing of audio devices. Although I can't offer solid advice on analysis software since I haven't picked one yet, I have done a bit of reading on the matter...

If you haven't seen this already, check out Pete Millet's work (Soundcard Interface) with audio tester (audioTester). Only reason I'm shying away from this is because I'm trying to stay Mac based for audio testing due to the lack of necessity for complicated drivers.

Also, your ADC will limit the accuracy and precision of your results. The Blue Yeti isn't bad but consider another flat response mic combined with this preamp: Product: UH-7000 | TASCAM

Might be more than you intended to spend but the unit has incredible specs! That Tascam will be my next purchase, along with software and a buffer for higher voltage testing.

Something else to look at, if you have a descent bench meter with a good sample rate: Using a DMM as a Low Frequency Analyzer

Just need to interface the microphone to it.

Don't have too much fun!
