Default Setting Amp Gain

I have a device designed that allows you to set amp gains up to clipping as well as find headunit (RCA) clipping volume, and I was wonder what kind of interest people might have in it. The circuit allows you to visually watch the waveform your amp or headunit/RCA source is producing with a laptop/computer using free software. (Audacity) The device is connected to a microphone input of a computer and to the amp or headunit, and you crank up the gain or volume while playing a test track until you see the wave deforming (clipping) and then back it off. The device is relatively cheap compared to a DD-1 or oscilloscope, and though testing has been limited (I only have one bass amp and headunit), it has worked perfectly. If you are interested in the device or have questions, please respond.

P.S. I plan to work on making the device compatible with Android phones/tablets headphone jack (if it isn't already), and there are apps that display the waveform.

Thanks,
Lucas Walker

Here is a picture of a prototype

I don't see pic either. But sounds pretty much like the dd-1 and the dd-1 is already cheap. So how cheap will urs be?

Hell yeah I would be interested at $20.

What device are you uploading the picture from?

Use imgur: the simple image sharer then post the direct link after hitting the icon that looks like a mountain with yellow background and it should post the full picture.
