WU2WAV converts SETI@home workunits into wav sound files. Of all the converters available that I know of, I dare say WU2WAV is the most accurate.
WU2WAV also has a small RFI detector, which attempts to tell the user if the WU contains strong (very strong) signals or not. I use this myself for trying to identify quick WU's in time, so that my WU-cache wouldn't become empty prematurely.
The RFI factor scale is, from weakest to strongest: Nope, Nah, Maybe, YEP, WHOA!
Use WU2WAV at your own risk. The author takes no responsibility for any damages that might be caused by WU2WAV.
Q: How did you find out how to convert the workunits into sound?
A little information about the format has been posted to alt.sci.seti and sci.astro.seti by SETI@home staff members. The rest was up to me to guess. To test whether I had found the right format or not, I converted workunits with strong RFI at first, but then moved on to reverse the process, make workunits and see from the graphics produced by the GUI SETI@home clients if I had found the correct format. Eventually, my guesses got better and better, I was able to see the signals from RFI workunits in the converted wav.Q: Why isn't the sourcecode released?
It is my understanding, that it is the wish of the SETI@home team, that anyone who stumbles on to the right format used in the WU's would keep it to himelf. Obvisouly for security reasons.Q: What are the system requirements for WU2WAV?
Well, if you're running Windows or Linux, and the SETI@home client, then your system should be able to run WU2wav.Q: WU2WAV doesn't work, why?
I don't know. You could try sending me an email describing what you did, any error messages you got from WU2WAV (run from ms-dos prompt (not real dos) to see any error messages under windows), what happened and what you expected would happen.Q: Why is the Linux version so much bigger?
The Linux version is statically linked, while the Windows version is not.Q: What processor is WU2WAV optimized for?
The Linux version is optimized for Pentium, but runs on every i386 compatible processor (I hope).Q: Does WU2WAV decode the workunits 'properly'?
I hope so. Workunits with strong RFI tend to prove this, the narrowband interference seems to be at the same frequency (when viewing work_unit.wav) as reported by SETISpy, for example.Q: Then why do I not hear the signals?
Perhaps it is too weak to be heard, or too high or too low in frequency for your ears? The SETI@home clients is atleast a thousand times more sensitive than your ears.Feel free to contact me with any further questions about WU2WAV.
