What is MultiWave ?
MultiWave creates a multichannel wave file from several mono wave files. It supports the WAVE_FORMAT_EXTENSIBLE format tag, which allows to store the mapping between the channels and the speakers on which they should play.
Common usages include the generation of quadriphonic and surround 5.1 files.

How does it work ?
MultiWave lets you define multichannel configurations. From stereo to surround 7.1, including quadriphony and surround 5.1, and everything else you can imagine. Simply select a wave file for each channel, and then create the corresponding
multichannel file! MultiWave processes the samples by blocks of 100 Kb, so you can use input files of virtually any size, without going out of memory.
Several options are available, to automatically select wave files for all the channels with only one click (based on file suffixes), to pad the shortest samples with silence, or to automatically save the result.
