Anyone know of a Windows package that will carry out spectrum analysis (audio spectrum, 15Hz - 17 KHz).

Ideally, it will be shareware or relatively low cost, be able to carry out an analysis of a sweep across the audio spectrum sampled from the microphone via a soundcard input.

Linearity/calibration with respect to the microphone is not desperately important, but if the package can output a calibration tone signal at line level for an external amp, this will help.

Don't want much, do I?
