I'm looking for an original/creative way to test audio quality (of both amplification systems including earphones, and of the devices that produce the sound including sound cards and portable music players). I was thinking of making a tone (perhaps a soft sine wave works best) that bends (I think that's the right term here) from 5 Hz (yes, that's very low) to 30 MHz (yes, that's very high). I need it to bend as smoothly as possible over, say, a twenty or thirty second period. And it has to be a single tone without overtones and undertones. The idea being that you can most clearly hear the sound quality as a function on all the tones ranging from lower than our hearing range to higher than our hearing range all across the spectrum. I asked a friend who's been working with Cubase and some other programs, but he can't find any way to do that. Can anyone here direct me in the right direction? Or perhaps refine my method to test audio quality?
I'm beginning to wonder if "bending" a sine wave is even possible...
