A few questions around export file formats:
1 Assume the session is 24 bit. When exporting from Ardour to a file for processing outside Ardour, would it be better to export at 24 bit, or 32 bit float? What might influence this decision?
2 When exporting from a 24 bit Ardour session to a file with lower word length, say 16 bit, is it recommended to apply dither? Which type of dither is recommended (my general reading seems to suggest triangular)?
