Speculumfree is a delay/comb filter effect plugin.

SpectriX

SpectriX is a free exciter and enhancer VST plugin developed by Obertone Audio. Compatible OS(s): Windows.

SpectriX is designed for mastering and simply enhances treble. It can also be use to reconstruct high frequencies on MP3 files and tape recordings which are lost due to high compression rates.

Most exciters work well on monophonic material but on polyphonic material they often create inter-modulation-distortion which is audible as “frizzle-noise” and treble “bursts”. Spectrix is different – it is designed to work well with all kinds of audio material: Speech, monophonic sounds and complex polyphonic mixes.

NOTE: SpectriX uses the hosts’s default GUI.
