Can I switch the audio track on a dual-audio file?
Yes. Every audio track inside the file is listed in the player menu and can be switched while the video is playing, without restarting it. Dual-audio MKVs — original language plus a dub — are the common case and are handled natively.

A dual-audio release carries two or more complete audio streams in one file. FoxDL reads them all from the container and lets you move between them from the same menu that holds the subtitles.
Because the switch happens inside the decoder, the picture does not stop and the position is kept. Files with five language tracks and eight subtitle tracks — the way many MKV releases are packed — are listed in full rather than truncated.
The 10-band equalizer applies on top of whichever track is playing, which is useful when a dub is mixed quieter than the original.
