I just found another, even cooler one! TrueRTA at
http://www.trueaudio.com/rta_abt1.htm . Intended for acoustic system
measurements with a teaser FREE basic software that is limited for that
application, nevertheless TrueRTA Level 1 not only includes a sine wave and
pink noise generator but also an audio frequency dual trace oscilloscope and
a low-resolution real time audio spectrum analyzer. The spectrum analyser is
showing me that I have a fair bit of hum being generated or picked up on the
sound card, even when my receiver and mixer are turned off. While I have
better ham radio related spectrum analyser software, this is the first I
found with an integrated generator. I would say the quality of the software
and user interface is good.

Cheers!
