Hi Damian,

Vorbis files have a header, which is usually a few kB in length and 
hence add a significant overhead to very short files. If you keep a 
separate table with sample offset and length, it is very well feasible 
to merge several short samples into a longer file and encode it "en 
bloc". You can even use proprietary Vorbis comments to embed this lookup 
table into the single Vorbis file, keeping all data necessary for 
decoding in one place.
