I've only just started to listen to these, but the audio quality on these seems to get better every year. One improvement that would be a huge help for future conferences is if the id3 tags could be set on these files prior to posting. For those of us using mp3 players it would be a huge help in figuring out what file is what. Right now the song titles are just a string of digits, with an unknown artist and "TASCAM DR-08" as the album title.
