I’d make the “bell” noise for around ten seconds, then kill the process with to hear the result.<\/p>\n While the laptop had a built-in microphone, I also had two old headsets that each had one. The jack one didn’t work, but the USB one did, and conveyed a nice clear recording.<\/p>\n To make the actual sound, I didn’t have a bell. I settled on clinking a spoon against a large coffee cup.<\/p>\n Everything seemed to work out fine; I’ll share the implementation soon:)<\/p>\n
\nIn my Feb 2<\/a> post I mentioned that the bell (‘\\a’) is apparently disabled in my flavour of Ubuntu (14.04). Yet, I want a bell-like sound for an upcoming experiment.<\/p>\nexec<\/code> function. (Once again: my Feb 2<\/a> post for details.)<\/p>\nman aplay<\/code> I learned about the arecord<\/code> function. From the terminal I keyed in<\/p>\narecord sounds\/beep0.wav<\/code><\/p>\nCtrl+c<\/code>. Next I’d key in<\/p>\naplay sounds\/beep0.wav<\/code><\/p>\n
