By default, all software supports multiple file extensions. SonicStage supports at least 4 different file extensions. The basic files that SonicStage supports are .AT3. However, not all of the extensions listed on the list are always used to save the effects of work in SonicStage. Very often, files with such extensions are used as source data files used by SonicStage.
SonicStage can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via SonicStage and try to save it in another file format, also supported by SonicStage.
