20Hz to 20 KHz is barely usable for audio. There are cheap digital scope kits on Ebay. That article requires an app that sells for $10. Why not add a bit more and get something that actually works?
My current scope is a Tektronix 2465A. It is four channel, and its -3dB point is 350 MHz. I got it for $189.42 on Ebay.
