           Summary: wav files have huge chunk sizes
    Classification: Desktop

wavenc name=enc created files all have a chunk size of 0x7fff0024 (you can
subtract 4 if you feel like it) which is of the order of 2 GB, regardless on
how small the file is. (The chunk size is encoded in the 4 bytes following the
initial "RIFF" string.) These files then get rejected by "other" programs as
containing invalid arguments. (The chunk size in the data section is also
similarly huge.)

The way I reproduced this:
Ubuntu lucid 10.04.1, linux 2.6.32-25-generic x86_64
gnome-sound-recorder 2.30.0
Record as: Voice, Lossless (.wav type)
gconftool -a /system/gstreamer/0.10/audio/profiles/voicelossless
tells you that
pipeline = audio/x-raw-int,rate=22050,channels=1 ! wavenc name=enc
