EN233 Lab
40 Pentium 4 PC 3.4Ghz, 1GB, sound card.
Contain MATLAB 7.0.4 version which we will use for some of our
audio/video exercises.
Find in “my computer” the network drive that maps to your ufp
directory under \\excelsior\Students. Normally it is mapped to z
drive. Create a cs525 directory that network drive and save your
work in z:\cs525. This allows you to login any computer to retrieve
the files saved there.
If you can not find the ufp directory mapped as a network drive in the
local machine. You can use c:\temp for your work but transfer to ufp
or CS Unix machines for storage.
Create a directory with your login in c:\temp directory and
Use c:\temp\<login> it to save your work.
Note that the content in c:\temp will be clean up periodically by the
system admin’s scheduled task. It may not be there next moring.
The front panel of the PC has green plug for audio playback.
The back panel of the PC has red plug for audio recording and green
plug for audio playback.
