Subject: Re: illustration needed (PRAAT & Audacity) From: Philip Dorrell <aud(at)1729.COM> Date: Mon, 20 Jun 2005 09:05:59 +1200For my book, "What is Music? Solving a Scientific Mystery" (http://whatismusic.info), I used PRAAT, (http://www.praat.org) which is licensed under the GPL, to create spectrograms of myself talking a phrase and singing the same phrase ("Twinkle twinkle little star"). PRAAT is easy enough to use, and you can output the spectrogram as an EPS file. You can see the spectrograms I made in the book's online preview (page 52 out of 134). Audacity can also do spectrograms. Philip Dorrell.
