How can I convert .vdjsample files to .mp3 format?
Converting VirtualDJ Audio Sample Files directly to MP3 Audio Files (.vdjsample to .mp3 conversion) should be possible. It appears, however, that your options are quite limited.
VDJSAMPLE files are basically OGG Vorbis Audio Files, and they can certainly be converted to MP3 Audio Files using, for instance, Audacity. This tool allows users to import VDJSAMPLE files and export them in MP3 format.
