* For low frequencies, pretty much any external sound card with a line input will work. External card line inputs generally have a range around 0-1 V whereas onboard microphone inputs only have up to about 50 mV, which just isn't enough sensitivity. The [http://vtluug.org/wiki/Lab-in-a-Box Virginia Tech Lab-in-a-Box] recommends the Behringer UCA202. To use a sound card oscilloscope on a regular basis, a circuit with variable attenuation is recommended (i.e. 1x and 10x). Compensation for the hardware and software gain can be done as part of the attenuator circuit or in software. | * For low frequencies, pretty much any external sound card with a line input will work.
