They can be used at any stage of production. Keep in mind ALL linear phase plug-ins introduce latency when using their linear phase algorithms. Some, including the new L-Phase plug-ins, have alternate algorithms that do not add latency. To use the L-Phase plug-ins when latency matters set the Precision to Non-Linear in the plug-ins Expert settings.
Hey scook, just did quick run through of the new presets in the L-Phase Equalizer. Very nice!
The two preset categories are now "Mastering" and "Mixing".
The 31 presets in "Mixing" all default to a non-linear setting in the "Expert" menu, so an adjustment is no longer required, when using these.
When you first insert the plugin, it is set to a "Default" preset, with a Medium precision linear phase setting. But if you choose one of the "Mixing" presets, it automatically selects non-linear. Of course, once you save a project, it recalls your settings.
On the other hand, all of the "Mastering" presets use the "Medium" precision linear setting. These will still require an adjustment in the "Expert" menu, if you wish to override the default setting.
