To get the total reading time of a wave file you have to read the headers of the wave file format. Those headers are really easy to decode and you will have no problem on finding the details of those headers on the net (google search with "wave file format" will do the job).

Once you can read those headers you will be able to
obtain the total number of samples of the wave. You can then divide this total number by the sample rate (also written in the headers of the file) and get the total playing time.
