Voxengo Releases Sub-frequency Generator Plug-in

With the introduction of a new PC VST plug-in LF-Max, Voxengo continues development of tools designed to perform low-frequency adjustments.

The main function of LF-Max is to add sub low-frequency content to the program material and to the individual mix tracks. Beside this it features distortion module like the one found in Voxengo 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.

Voxengo Subfrequency Generator

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). Theoretically, plug-in should have the flavor of outboard 24-bit DSP processors which is usually subjectively considered by audio engineering professionals as “better sounding”.
