Sample Recording Sessions
These recordings have been made to evaluate the performance of a series of voice recorders.
Four recorder types were tested. Each test took place in the Boeing Auditorium in the FXB Building at the University of Michigan (http://inst-tech.engin.umich.edu/facilities/detail.php?roomid=37)
The four recorders were:

The first series of tests was done with the voice recorders placed on the floor in the center of the stage. The Optura 60 was placed slightly in the audience to record a sample powerpoint slide.
The second series of tests ( - Lecturn added to the file name) had the recorders sitting on the lectern. For this test, the speaker walked around the perimeter of the room to test distance clarity.

In Conference Use
A selection of these recorders will be used to store the proceedings of the 7th Sakai Conference. Raw files (as sampled on this page) will be available locally the evening of the conference day. Processed files will be made available on the web after the conference. There are 10 sessions that will need to be recorded simultaneously.
Several solutions have also been suggested to record slides, video or both. For 10 concurrent sessions, an estimate of cost ranges from $12,000-15,000. The solution presented here is provided as a low-cost alternative. It will require, however, significantly more post-processing effort. For more information on these alternative solutions for future conferences, please speak to the conference staff.
