Same thing.

Well, it's mostly to see if people can safely be lazy with research sounds.
mp3s are a very convienant format for people to use in many places. It's
much easier to distribute mp3s instead of {RAR,ARC,ZIP,bzip2} compressed
audio files. Portable mp3 voice recorders are becoming cheap and available.
It wouldn't be difficult to make a harddisk recorder that saved mp3 instead
of sampling speech with DAT recorders.
Aparantly the interest was generated recently when a phonetics publication my
professor reads published an article that detailed a speech study in which the
speech was recorded on a Sony MiniDisc recorder. Aparantly a number of people
doubted the author's results because no one has established what mp3 (and
other similar) algorithms do to speech.

No problem ::-)
