Because somehow this email arrived to may inbox three months later,^^;, it is a good time to write a reminder.
- eToys:
It would be very nice to have support for Analog Input in eToys.
For a month or so, Etoys has a support for Analog Input, in a sense that it can basically do what amixer does.
Etoys has been supporting audio input and various ways to analyze it. For example, if you launch Etoys, go to the treasure box, bring Object Catalog out, go to "Multimedia" category, and bring up "SpectrumAnalyzer". By talkin, whistling, etc. you can see what it does. It has different kinds of display, etc.
However, the current SpectrumAnalyzer was written more or less for a demo, and not really up to the real use. As I summarized at:
http://dev.laptop.org/ticket/4586
Combined with the underlying facility for analog input in Etoys, kids could write their own programs by using the input data to analyze it and play with it. Also, we could show the same data in different representations, such as time domain and frequency domain, at the same time side by side, so that a wave can be viewed in various ways.
I asked Arjun while ago if he would have time to try to enhance SpectrumAnalyzer in Etoys. He said after polishing up Measure for these deadlines, he wants to give it a shot (I still think he is the ideal person). However, if others on the list have ideas and time and desire, please think about enhancing SpectrumAnalyzer (or write a better one).
Thank you!
