wav
     
         (waveform)
        /wav/, /dot wav/ A {sound} format developed by {Microsoft} and
        used extensively in {Microsoft Windows}.  Conversion tools are
        available to allow most other {operating systems} to play .wav
        files.
     
        .wav files are also used as the sound source in {wavetable}
        synthesis, e.g. in E-mu's {SoundFont}.  In addition, .wav
        files are also supported by some {MIDI} sequencers as add-on
        audio.  That is, pre-recorded .wav files are played back by
        control commands written in the sequence script.
