I am very new to Audacity and audio editing in general. I need to generate a rising or falling tone (think slide whistle) approximately 1 second in duration, with a specific starting and ending frequency for a research study. Can anyone help me figure out how to so this? Thanks in advance for your help!
Use Audacity 1.3.13 http://audacityteam.org/download/
“Generate menu > Chirp”
Well, that was waaaaayy too easy - after spending the last 4 days straight trying to figure out how to do that! 
Thank you so much for your help!!
