Add the directory containing the record to your WFDB path, then use WAVE just as you would to view a record stored on your local disk. For example, suppose the WFDB path is:
. /usr/data http://www.signals.r.us/data ftp://sand.bar.com/pubIn this case, WAVE would look for input files first in the current directory (.) of the local disk, then in /usr/data (which might be local or might be part of a networked file system), then on the signals.r.us web site, and finally on sand.bar.com's FTP server. Unless you have a slow network connection, you may not notice any difference between viewing locally and remotely stored records.
