From: Nedko Arnaudov &lt;nedko(a)arnaudov.name&gt; Subject: [LAD] [ANN] lv2fil version 2.0 "New hope" released To: linux-audio-announce(a)lists.linuxaudio.org, linux-audio-dev(a)lists.linuxaudio.org, linux-audio-user(a)lists.linuxaudio.org Date: Saturday, June 13, 2009, 10:40 AM Four-band parametric equaliser LV2 plugin. DSP code by Fons Adriaensen. Homepage: http://nedko.arnaudov.name/soft/lv2fil/ Screenshot: http://nedko.arnaudov.name/soft/lv2fil/lv2fil.png Tarball download: http://nedko.arnaudov.name/soft/lv2fil/lv2fil-2.0.tar.bz2 http://nedko.arnaudov.name/soft/lv2fil/lv2fil-2.0.tar.bz2.sig = Overview = Stereo and mono LV2 plugins, four-band parametric equalisers. Each section has an active/bypass switch, frequency, bandwidth and gain controls. There is also a global bypass switch and gain control. = DSP = The 2nd order resonant filters are implemented using a Mitra-Regalia style lattice filter, which has the nice property of being stable even while parameters are being changed. All switches and controls are internally smoothed, so they can be used 'live' whithout any clicks or zipper noises. This should make this plugin a good candidate for use in systems that allow automation of plugin control ports, such as Ardour, or for stage use. = GUI = The GUI provides knobs and toggle buttons for tweaking filter parameters. It also provides frequency response widget with differently coloured curve for each section and separate curve for total equalization effect. The GUI uses the External UI extension. lv2rack (part of zynjacku) supports this extension. Ardour-2.8 needs patch to support the external UI extension. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0> -----Inline Attachment Follows----- _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev(a)lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
