There are programs which can compress these wav files to MP3 files but if this can be done at the same time when giving CQ depends a lot on the computer used. A clunker will surely not do it. There is of course the possibility to do this after the contest. Enough harddisk space during the contest is necessary.

You can try the Ogg Vorbis compression codec that is better than mp3.



And programs like SOX to record an compress in background, in linux it's
easy cake, just a script.

73, fede.
