J1000 - Alpha, Beta, Delta & Gamma EQ Plug-ins which are not available anymore and are discontinued by the developer.
J1000 DELTA v2.0
is a mixing EQ with a twist. It shares the same HP/LP and output section as Beta. The obvious differnce is the way Delta handles audio via it's tilt and concurve modules. Actually, they are just pairs of filters that are set to work parallely. In case of tilt when one filter goes up, other goes down. Since their central frequencies are far apart (at default they are 50Hz and 10.5kHz), it results in spectrum tilting. Horizontal fader [F] controls central frequency of tilting, where gain remains zero. In case of concurve, which name derives from convex/concave curve, both filters react the same way, so when you move [C] fader up the spectrum "smiles"
, and when you move it down it "frowns"
. Loudness difference is automatically compensated. Horizontal fader [Q] adjusts bandwidth of opposite filters. Delta is suitable when you want to preserve the natural color of instrument, optimize it's presence in the mix and, figuratively speaking, adjust it's brightness and contrast.
J1000 GAMMA v2.0
is an equalizer intended primarily for mastering, probably first of it's kind. It is based on Fletcher-Munson curve, allowing you only to accent the parts of audio spectrum where ear is less sensitive and lower the ones where ear is more sensitive. Gamma can produce quite satisfactory results with non-synthesized music, but I developed it for my own personal mastering needs that revolve around soft-synths which often sound flat and harsh. Six faders control gain amounts of six corresponding peak filters. Each filter has fixed Q factor and few selectable central frequencies, except for the last one (labeled F) which is permanently set at 12.8kHz. On the right part of interface there is master multiply fader which controls total amount of EQ-ing applied and also a simple button for reducing input signal by 3dB. Beware - this plugin is tempting to be overused.
J1000 BETA v3.7
is very similar in functionality to Alpha, but adapted to mixing. It's frequency faders work in exactly the same way. Gain range is increased to 6dB (12dB with x2), which is also modest compared to usual mixing equalizers. There is no fader to contiunally adjust Q factor, but you can choose from four bandwidth curves that cover most needs. Also, high-pass and low-pass faders work different than in Alpha. They control frequency at which cutting occurs, which is traditional way of controlling HP i LP filters. Their steepness is non-adjustable and it was selected to preserve natural sound as much as possible. If you need drastic EQ-ing this is not an adequate plugin for the task. On other hand, if you wan't subtle tool for enhancing timbral properties of an instrument or voice, rather than altering them beyond recognition, Beta will suit just fine.
J1000 ALPHA v3.8
is an equalizer made for fine tuning in post-production. It separates stereo into mid and side signals and allows you independent equalization over both of them. Each of two sections consists of four identical peak filters. The controls are classic F/G/Q that you can find on every fully-parametric equalizer. Small distinctition is that two horizontal faders, located on top of each section, control filter frequency. The upper [F] is for rough selection and it has range from 50 to 12,500Hz, while lower [f] is for fine adjustments in +/-20% range. Vertical gain fader [G] can boost or cut signal by 3dB. This may seem too little, but for mastering it is quite enough and if you think you really need more you can always use x2 button that doubles gain for that filter, i.e., gives you +/-6dB operating range. Q factor is continually controlled by third horizontal fader [Q]. Master section at the right has high-pass and low-pass filters, input gain and stereo width faders. High-pass and low-pass filters have fixed frequencies and faders actually control filters' steepness. Stereo width adjustment is done with two opposite filters, so that bass remains almost intact.
