Reads data from a .wav file into an array of waveforms. You must manually select the polymorphic instance you want to use.
(Windows) You must have DirectX 8.0 or later to use this VI.
Note This VI retrieves only uncompressed wave files. LabVIEW uses large amounts of memory when reading an entire wave file at once. Instead, read wave files in chunks.
