New LF-Max Sub-Frequency Generator Plug-In from Voxengo

August 5, 2005

The main function of LF-Max is to add sub low-frequency content to the program material and to individual mix tracks. It also features a distortion module like the one found in Voxengo's LF-Punch plug-in. Signal flow is different from LF-Punch, though. LF-Punch processes low-frequency band "in-place" while LF-Max mixes distorted signal result with the original low-frequency signal.

Internally, LF-Max produces three signals: the first one is the original low-frequency signal which is extracted by means of an adjustable crossover filter; the second one is the distorted signal which is generated by applying distortion to the original low-frequency signal; and the third signal is the sub-frequency signal which is synthesized from the original low-frequency signal. These signals can then be mixed together in the desired proportion.

LF-Max also reproduces finite word-length effects on all processing stages of the plug-in (but without any kind of clipping occuring).

Voxengo LF-Max features:

  • Sub frequency generator
  • Distortion module
  • Two distortion modes
  • Distortion, sub and original signal blending
  • FX monitoring switch
  • "A-to-B" comparisons
  • Mono-to-Stereo, Stereo-to-Stereo processing
  • All sample rates supported
  • 24-bit DSP chip imitation
  • Native assembler DSP code
