Software questions MiniMens

[Robin Hufford]

Hello Bernhard,
     I just came on line to correct my previous post and found your reply.
Thanks.  I whipped out that post last evening after just reading a book on
guitar making where it was stated that a 3 Db increase represented a doubling in
loudness.  I began to wonder myself afterwards and, having checked with Benande,
found that c. 6 Dbs correspond to a doubling as you say.  Apologies to all for
the error.  Thanks for clarifying the matter.
Regards, Robin Hufford
