I wanted to draw everyone's attention to some plugins from linuxDSP,
which can be found here:
http://www.linuxdsp.co.uk
They are available as LV2 plugins compatible with most recent versions
of Ardour and Qtractor (and other hosts that support the required LV2
extensions) and also as linux VSTs for hosts such as energyXT, renoise
(and also Qtractor when built with the VST headers). They are also
available as standalone JACK client applications.
The most recent releases (the Pro-EQ and Pro-Dynamics) are specifically
intended to add professional quality channel processing to DAWs e.g.
Ardour, and in addition to high quality signal processing also feature
an innovative resizable GUI.
All the LV2 plugins have a GUI that will display the same way in a GTK
host as in a Qt host - which is not always the case with other plugins.
The plugins are not all free, but as one of the few full-time developers
of linux audio software (with over 20 years professional experience of
pro-audio), it is necessary to cover the cost of development and
provision of the software - and I think they are still very reasonably
priced.
Thanks.
