sorry to post three times in a row, but i wanted to answer this and ask questions too... snarlydwarf;267481 Wrote: > And MP3, Ogg and FLAC are done in software on the SB... so?

But > again, that isn't where the vast majority of users see problems. i'm not suggesting there are problems with transcoding as it is done now, i was answering a criticism of my proposed fat device. snarlydwarf;267481 Wrote: > It would be. > > O(n) searches of 20,000 tracks is painful. > > Databases have indexes. > > Tracks are searched by Artist, Composer, Name, Album, Genre, Year.... > all of those need indexes.
