Numerical Sound Bass Tilt Filters (BTF) contains 36 convolution filters at each Reason sample rate to brighten or darken your sounds in the most transparent way possible. They can be used in a wide range of applications: from mastering to adding warmth or clarity, from creative sound design to changing the emphasis of effects - or even emulating the sound of a vintage recordings. Dark Tilt filters can remove harshness and blend sounds into a mix. Brighter Tilt filters emphasize the high end, adding presence that can keep sounds from getting lost in the mix.

BTL cutoff frequencies are at C2 (65 Hz), C3 (131 Hz) and C4 (262 Hz) each with 6 levels of bright and dark - a total of 36 filters at each sample rate offered by Reason.
This convolution software makes precision sound possible that is otherwise unattainable with parametric and multiband EQ because of its inherent lack of resonance curves and phase distortion.
Stereo Width, Gain, Pan and Dry/Wet controls make it easy to mix and shape the sounds.
Audiophile design supports 44.1, 48, 88.2, 96 and 192 KHz sample rates with processing transparently optimized for each sample rate.
