Why save audio file in WMV format?
Audio files should not be stored in WMV format, as this is a
Windows Multimedia Video file, and is intended to store moving
images andsynchronizedaudio (i.e. a movie or video). Furthermore,
files saved in WMV may become DRM locked if the application detects
a copyright signature, and therefore require a license to transmit
between computers. Use WMV format when no other formats are
available.
