For sound in general I think a wrapper of the Ogg Vorbis libraries would be very nice. Ogg files take as little space as MP3, but have better quality and being free of any patent restrictions. Besides new MP3 players seem also to now add support for ogg. http://www.vorbis.com/ http://www.vorbis.com/faq.psp Besides Ogg works on most platforms. Do anybody know of software/documentation/theory for matching two sound files like Language training programs do. I mean that you try to pronouce the word and the program tells you how well you did compared to the pronounciations of somebody who speaks the language. You have to account for different pitches etc... so how do they do it? -- This is Ada95 land. On quiet nights you can hear C programmers debug.
