fat1.lv2 is identical in functionality to the standalone JACK plugin zita-at1. The only difference is that it is an LV2 plugin, which makes it much more convenient when working with modern Linux DAWs.
Vladimir Sadovnikov has just released version 1.0.18 of his audio plugin suite, LSP plugins. This release celebrates one year since LSP plugins 1.0.0 release. All LSP plugins are available in LADSPA, LV2, LinuxVST and standalone JACK formats.
This release includes the following new plugins and changes -
SpectMorph allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute.
Also interpolating between two samples of the same instrument (different attack velocity of a piano) could be interesting.
LSP (Linux Studio Plugins) is a collection of plugins which aims to bring new, non existing plugins to Linux. All LSP plugins are available in LADSPA, LV2, LinuxVST and standalone JACK formats.
