What is this virtual page all about ? -- Click here and listen.Couldn't attend the TAPR meeting in March of 1995 ?
Well - here is your opportunity using RealAudio to listen in to both the Sunday workshops. Using the Adobe Acrobat format (pdf) we have provided the overheads and between the audio and the overheads you should be able to get a lot from the workshop you couldn't attend!
- You should download and then print out the overheads.
- You should print out the time references for the presentation you plan on listening to.
- Then select the RealAudio link to the presentation audio track and follow along!

Note: The audio on this seminar was not great. We have found that setting the audio slider on the RealAudio application to 50% or less and turning up the speaker elimnates most of the noise that was compressed in the segment. We apologize for the quality -- but hey! This is our first stuff and was done long before thinking of doing this.
