Any audio editing and converting software will be of use. Suggests FlexiMusic Wave Editor. Play and record the ram audio files in the software then using "Save As" command convert and save the recorded ram files as Mp3 files.To save the file as Mp3, need to install a separate command line Mp3 encoder/ decoder. Lame win 32 will be of use. Software is easy to use, downloadable and free to use as trail version.
