How to slow down a song?

How do I slow down a song? It's just some ambient noise and I want it slower - and don't mind the pitch changing too.

Seems like no big deal. I changed the playback tempo using the slider and it sounds fine. But when I render it comes out at regular speed. Suggestions?

The speed control slider is only for previewing; it has no effect on
renders. What you want to do is timestretch. Place your mouse pointer
at the end of the song just like you would for trimming, but hold the
Ctrl key down while you move the mouse to the right. This will stretch
out the length of the song instead of looping it.

If you have SoundForge or SoundForge XP, use Effects/Pitch Shift
instead. It will give you a much better quality result.

The way to do this in Vegas is to right click on the event and go into the Properties dialog. There you will see a Timestretch/Pitch shift section.

The timestretching (change length preserve pitch) and pitch shifting (change pitch, preserve length)are not very good sounding in Vegas 3.0. However the 3rd option (change length and pitch) does sound very good, assuming you don't mind the pitch change.

According to a message from SF, Vegas 3.0 will have improvements in the timestretch features. Of course you can also use other programs for this as well. Acid does a very good job, Sound Forge has lot of tweakable paramters.

Vegas 3 has a new, voice-optimized timestetching mode. Not bad for many situations, really good for sqashing vo up to about 20%. For serious timestretching, use SoundForge- not real time like Vegas, but since it doesn't have to be real time, more advanced processing algorithms can be used.

Actually, when I want the highest quality timestretching, I use Prosoniq Time Factory. However, it's strictly an "offline" process, no preview and very slow. But the results are the best I've ever heard, esp. at extreme settings.
