Convert the recording to a digital format. Be sure to capture a hissy section with no music or background noise.

Sample the portion of the recording with the hiss, then use a software tool to extract those frequencies from the musical portion of the digital recording.

I have done this with CoolEdit with pretty good results.

There are shareware versions of this software online. If interested I will post a full feature version to http://launch.groups.yahoo.com/group/KennysArchive/ when I get home later today...
