Generating a frequency Sweep test track in audacity

[cd1234]

Hi im a newbie at Audacity and im trying to create a frequency sweep track as a testing track, i would like to create one that starts at 1 hz and sweeps up to like 4-500 hz increasing by 1 hz each second of the track is there any way to do that without going into the generate sine wave option and manually changing the frequency level is there a plugin that will do this? im posting here b/c the other parts of the forum are set to read only and cannot add new posts, please dont ban me im just trying to figure out how to make a test track i can use in my test videos like to test speakers and hard drive speakers I do have videos of this up on youtube, at youtube dot com / coondogtheman1234 or just look up hard drive speaker on youtube and look for videos by coondogtheman1234

thanks for any help that you can provide

Quick example. Put this in a .ny file. (Copy an existing one and edit it if you are really new to Audacity.)

(fmosc 0.0 (pwl 5.0 500.0 5.001))

That's a 5-second linear sweep from 0 hz to 500 hz. Since it's linear, the frequency change is perceived to "slow down" as the frequency goes up.

To alter the speed/frequency of the sweep, read up on pwl (lower-case letter L, not numeral 1, "Piece-Wise Linear".)

Actually, I don't know why I didn't think, just use pwe instead of pwl if you want an exponential sweep.

(fmosc 0.0 (pwe 5.0 500.0 5.001))
