New ideas come from the kids. Some time ago I promised to my daughter to get her a microphone if she improves her grades a lot. Now she got her report, and I had to take her to a professional music store to buy the microphone. She got an AUDIX OM 2 microphone. We also got an USB Audio Capture device (EDIROL, UA-25, USB powered).

We connected the microphone to EDIROL and EDIROL to my Mac. Results were extraordinary. The quality of the recording is much higher than what I was able to produce with my Logitech microphone. There is no comparison. With Mac’s GarageBand we have now created a number of rather high quality recordings. This statement “high quality” means that we were able to produce a very good recording of whatever I was talking or my daughter singing. It is not a statement about the quality of our performance.

Now I plan to get a second set of the audio capture devices. I see a new version of my calculus course on its way: Garage Calculus, a series of calculus podcasts produced by GarageBand.
