[linux-audio-user] how to encode w64

hi, im wondering how to encode several >2gb w64 files to a lossy format like mp3 or ogg this is what ive tried so far: sox: Failed reading itz.w64: Do not understand format type: w64 flac: ERROR unknown format oggenc: ERROR: Input file "itz.w64" is not a supported format ardour: plays ok, but no encoded formats available in export dialog cubase sx, wavelab, nuendo in vmware: wont launch samplitude in vmware: nothing happens soundforge8 installer in WINE: wont launch my vmware trial expired, and i didnt get to trying foobar2000 or soundforge8 in vmware, but even if they did work, the audio would have to be sent over a samba connection at a few mb/second..if samba didnt choke on the >2gb files to begin with..,. ..so hopefully linux can do this seemingly simple audio task..any ideas?
