Hi Andreas, Thanks for your query, but I was unable to send email to your location from mine due to email restrictions on your end --- so I'm hoping you'll see this. Please let me know if you do. I hope it's OK to reply through the mailing list because I don't have any other way of contacting you. (BTW: Do other LAU people have the problem wherein they are contacted by a reader only to find that they cannot respond? What should we do in this situation? Is use of this list OK?) I'm developing this software as a research product into computational acoustics. I haven't decided what type of licenses to offer, but I'm leaning towards GPL or similar. Regards, Dave. Replying to:
