Test tone generator?

Hi, I was just looking for a quick way to test how low/high my speakers/headphones/hearing can go, and came upon this program called Test Tone Generator. You probably already know it. It basically does noise and sine waves of whatever frequency, does sweeps, and works in mono and stereo. Simple enough. Before I cough up the $32 for it though, I'd like to know if there are similar better (or cheaper) programs.

Thanks.

Excellent, thanks a lot. VB generator seems to do pretty much the same.

OK, some stuff is happening. Been testing sine waves, and VB generator seems to output at 44.1 kHz. If I set Vista32/ATI HDMI and Win 7/whatever comes with HP DV5 laptops (tried both in different PCs), to 48 kHz output, I can hear a background overtone (I think it is an overtone). If I set Windows output to 96 kHz, it's less audible. If I set it to 192 kHz, it's inaudible and it sounds as pure as when I set it to 44.1 kHz.

This also happens with my ATI card and HDMI receiver (Pioneer VSX-01), even when my receiver takes 192 kHz, but downsamples to 96 kHz for processing (and shows "96 kHz" in the display as if it was receiving 96). Am I correct in assuming that upsampling and outputting in Windows at 192 kHz and then downsampling in the receiver to 96 will yield a better result than just upsampling and outputting in Windows at 96 kHz? Am I right also to assume that my receiver's resampling is better than Windows'?

The Audio Rightmark program (freeware) provides a lot more than just a tone generator. The speaker testing module might relate to headphone testing.
