Using JMF player.setRate to playback mp3 files at different speeds

Hi, I am a somewhat new Java programmer and i have managed to set up a player, and playback a local mp3 file, however, I would like to be able to change the speed/tempo at which the mp3 is played. I believe player.setRate(float a) is the way to do it, however, calling that method after realizing, but prior to starting does not seem to make any noticeable difference. I tried arguments such as setRate(1.0) and setRate(1000.0). I also am aware that in the API, it says that players only garuntee a rate of 1.0, so I suppose it is possible I may not be able to change this rate.

Thanks in advance for any insight.

According to the documentation,

Quote:

---

The setRate method returns the actual rate set by the Clock.

In your program, what value does setRate(...) return?

It returns 1.0 even if I enter 100.0 in as an argument, which would explain why it isn't changing the rate of play.
