The first samples above were taken using only my soundcard as stated. I just put a 1:50 resistor divider to make sure I remained in the 1V range of the line input
Of course, you're limited to the 20 Hz - 20 kHz range at best, and you can't measure levels as the soundcard input stage is driven by Windows. To make things worse, you have no idea of the DC offset as it is filtered out, but well, it gives an idea.
The second samples were taken with a handheld (discontinued) Tektronix THM550 like
this I borrowed from a colleague.
