Timeless comes with two high quality filters, each with six different sound characteristics. These multimode filters are based on our award winning filters first developed for FabFilter One. You can use them individually or combine filter characteristics to create your own sounds in any way imaginable. Both filters are stereo filters.

You control each filter with the following settings:
Frequency and Peak
The filter frequency is adjustable over the entire audio range with variable resonance (yes, it will self-oscillate at maximum resonance!). The Frequency controls the center frequency of each filter and can be controlled in real time, either manually or via external devices. The Peak knob adjusts the filter
resonance. A little resonance will cause the filter to create warmer and more characteristic tones. The Pan ring around the Frequency knob varies the center frequency for the left and right audio channel.
FabFilter Timeless offers the possibility to choose between three different filter characteristics:
Filter routing
There are three different way's of configuring the filters in the audio signal path.
Serial will put both left and right channel of the delay lines first thru filter 1 and than thru filter 2.

Parallel: The output of delay line 1 into both filter 1 and 2, and the output of delay line 2 into both filter 1 and 2.

Per channel: delay lines and filters are working in 2 groups. Delay line 1 uses filter 1 and delay line 2 uses filter 2.

The settings of the filter parameters can be stored as a section preset.
Linking the two filters
When you want to change the Frequency and the Peak setting of both filters
simultaneously, just hold down the Alt key while turning a knob. For example, you can set them up as dual, resonant band-pass filters and sweep the cutoffs simultaneously. This configuration will give you access to all manner of 'vocal' sounds, as well as even more dramatic formant-based timbres.
To adjust both filters simultaneously, but in the opposite direction hold down the Ctrl and Alt keys (Windows) or the Command and Alt keys (Mac) and drag the knob for filter 1 or 2.
Auto-mute self-oscillation
It is possible to prevent the filters to self-oscillate if there is no incoming audio signal. This will make higher peak settings possible while the filters will not be howling continuously when you stop playback in your host.

The interactive filter display gives an overview of the filter parameters and makes it very easy to adjust the filter parameters.
