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 a distortion module like that 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 occurring). Theoretically, the plug-in should have the flavor of outboard 24-bit DSP processors which is usually subjectively considered by audio engineering professionals as "better sounding".
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.
LF-Max is available for purchase for the introductory price of US$49.95 (normally $59.95). LF-Max can be also purchased as a part of a plug-in bundle together with the LF-Punch plug-in for US$89.95. A demo version is available.
