SignalScope / Re: dual microphone input
« on: March 04, 2008, 09:28:13 PM »
thanks again, Ben.

I think I've almost got it. Tomorrow I'm planning on looking at a 4-channel microphone mixer sold by radioshack ($29). If I'm correct, this will have a stereo line out that should go into the audio input jack and be visible as 2 channels in SignalScope. Thanks again.

Thanks again,

Thanks for the tips, Ben.

Sorry for my ignorance.

If I read you correctly, the audio input jack, although a single jack, supports 2 inputs.

Is the jack the same as a headphone jack? Am I looking for a connector that is the same as a headphone connector? Will such a connector keep the 2 mics separate and be seen by SignalScope as 2 inputs?

Thanks, in advance.


SignalScope / dual microphone input

I'm looking for suggestions to get dual (cheap) microphone input for display in SignalScope. The critical issue is to be able to separate the microphone inputs and compare signals from a common source. This is for teaching purposes, to display time lags and amplitude changes, so the quality is not very important. (Did I say cheap?)
For example, its not clear if the Griffin iMic can be adapted for two micorphones. Another possibility would be to plug in two griffin iMics, each with its own microphone, but its not clear if this would cause my powerbook to self-destruct or whether SignalScope could simultaneously display both inputs.

Any feedback or suggestions is greatly appreciated.
