it would be nice to see something like this integrated into ardour, at least in the output channels as an option. i'd like the ability to get a standard reference level to compare against apart from the 'ok, it has clipped now, turn it down a tad' level it currently shows :) porl 2008/8/4 Raphaël Doursenaud <rdoursenaud@xxxxxxx>: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Fons Adriaensen a écrit : >> Hello all, >> >> The first release of jkmeter is now available in the >> usual place: >> >> <www.kokkizinita.net/linuxaudio/downloads> >> >> Also updates of japa and jnoise (mostly maintenance, >> but see also below). >> >> >> From the README: >> >> >> jkmeter-0.1.0 (03/08/2008) >> -------------------------- >> >> Jkmeter is a horizontal or vertical bargraph level >> meter based on the ideas of mastering guru Bob Katz. >> See <http://www.digido.com/bob-katz/index.php> and >> follow the links on 'level practices'. >> >> This is the type of meter you want for live recording, >> mixing and mastering.
