Altona releases Tilt&Shelf equalizer plugin


Developer: Altona

AltonaTiltShelfMinusOneAltona has announced the release of Tilt&Shelf, an innovative new equalizer plugin that offers a better sounding and much easier to use alternative to graphic, parametric and even shelving equalizers for general shaping of frequency spectral content.

Tilt&Shelf is a minimum-phase equalizer with continuously-variable slope and maximally-flat group delay. It’s available for Mac OS X and Windows in Audio Unit and VST plug-in formats.

Tilt&Shelf was designed to allow tilt responses with a variable slope across the entire frequency spectrum. Two controls allow the slope to be freely adjusted from -12dB/oct to +12dB/oct. In addition, the same two controls can be used to add low/high-frequency shelves at any gain from -20dB to +20dB.

Tilt&Shelf was designed specifically to have a maximally-flat group delay, resulting in minimal pulse distortion. In addition, the group delay is maximally flat at any equalizer setting, independent of gain, frequency and slope.


  • Gain range: ‑20dB to +20dB
  • Frequency range: 20Hz to 20kHz
  • Sampling rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 192kHz, 384kHz
  • Plugin formats: Audio Unit, VST (both 32‑bit and 64‑bit)
