loPass is a filter plug-in designed to deliver precise spectral shaping with exceptional clarity. It maintains an absolutely flat passband response, ensuring that the original signal remains transparent while providing highly selective filtering capabilities.

The plug-in offers an adjustable filter slope ranging from gentle 6 dB per octave up to an extremely steep 192 dB per octave, allowing for detailed control over the frequency cutoff. Its internal processing employs double precision with 52-bit accuracy, ensuring clean and accurate audio results across all settings.

Additional features include split channel stereo control for independent processing of left and right channels, and a configurable overshoot display to visualize the filter's behavior. loPass also provides a variety of presets that serve as useful starting points for different filtering needs.
