  Sounds like a weak radio signal! I wonder if we could pass it through a deringing filter to remove some of that noise, eg, like these guys have done: http://www.cs.rpi.edu/~oztanb/Papers/spie07paper.pdf http://www.cs.rpi.edu/~oztanb/Papers/spie07paper.pdf

  Similar results - converting to a square image at 8bit then lowering JPEG quality just gets noisy in an uninteresting way: sox mo.wav -e unsigned -b 8 -c 1 -r 48k mo.raw bytes=`stat -f %z mo.raw` width=`echo sqrt\($bytes\) | bc` square_bytes=`echo $width \* $width | bc` dd if=mo.raw of=mo_square.raw bs=$square_bytes count=1 gm convert -depth 8 -size ${width}x${width} gray:mo_square.raw -quality 50 mo_square.jpg gm convert mo_square.jpg gray:mo_square_jpg.raw sox -e unsigned -b 8 -c 1 -r 48k -t raw mo_square_jpg.raw mo_jpg.wav
