<multimedia, file format, filename extension> (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.
