I need help changing speed

Hello, I’m new here. I’m a total noob with audacity so please bear with me.

I have a clip that is 6 seconds long. I have reversed it but need to slow it down 800 times. How do I do this?

The easiest way is to use the “Nyquist Prompt” effect.

  1. Select the 6 second track
  2. Effect menu > Nyquist Prompt
  3. Enter the following code:
(force-srate (* 800 *sound-srate*) s)
  1. Click the OK button and wait a couple of minutes for it to complete.
    Note that “slowing it down” 800 times will make the pitch so low that it will probably be inaudible.

Oops! I realized it was 800% not 800 times.

You see, I heard this story concerning a hidden track from a a Weird Al album called Bite Me. Which is a bunch a screaming and stuff done by Al and his band (Lampooning Nirvana’s hidden track ‘Endless Nameless’). However…Well I’ll let this snippet from the Weird Al Wiki explain:

The six-second snippet is also the base of a backmasked message (somewhat). When the song is reversed and slowed down 800%, there is a hidden song inserted. The lyrics are faint but clearly audible at 17 seconds (of the slowed down version) the lyrics are:

When we cannot ask the forest for a moment’s shade

Though every ray of sun cuts like a razorblade

And we cannot ask the river for water

If she has none!

This was discovered in 2004, and appear to be from David Hallyday’s “Tears of the Earth.”

Now, I want to do the reverse/slow-down treatment and see if it’s true, then present my finding on YouTube.
