You can convert the file for free using a free download program or Windows Media Encoder and then play in Windows Media Player, assuming that Real will let you convert from .ram to whatever format you want. Or, you can check out any plug-ins that real player may have that you can use as trial versions and then just keep on using new programs. Cnet.com has a download section where you can search for the "top programs" based upon user ratings. Another option is to download a program called "Audacity," which is a free audio editing software that converts to and from .wav files. It is a little more sophisticated than a basic music player, but you can also digitally alter signals in different ways with free plug-ins, for example: reverb, phase shifter, speed-up, etc.
Worst case scenario: Real doesn't let you convert from .ram, in which case you COULD use Audacity to record the audio in real-time and then manipulate the file in Audacity to speed it up. This takes a long time because you have to play the actual file in slow mode, but it works.
