Frequency response graph desired for custom setup

[racecannon]

Is there an application that will allow me to hook my computer up to my stereo system to play sounds at different frequencies for playback through the speakers so I can see what the frequency response graph looks like for my particular setup?

Take a look at REW

I've not yet used it, originally for room EQ, has been a number of add on so it also does distortion etc...

I've been using REW for 12+ years. I was alerted to it while on the Home Theater Shack site. I use it strictly for room equalization.

You also need a calibrated microphone in addition to a PC and REW.

Behringer, Parts Express and Mini DSP all sell the same calibrated mic. It comes with an individual correction file to assure flat response. The file is a direct plugin to REW.​

The results from REW, etc. are extremely close to what the auto room equalization setup on my surround processor calculates. They are so close I don't bother with the auto eq.

I picked up one of these this past fall. Would probably work well for something like this, though there are likely more modern solutions available nowadays. Thus far, all I've done was to plug it in and watch the funky graphs, which it works well for:
