This compressor has the lowest total harmonic distortion of any plugin we have seen, including desktop units. At the heart of it is a unique envelope follower design that makes it possible to compress the signal without creating distortion harmonics. On the spectrum of compressor tone that ranges from "vintage analog" to "pristine digital", this plugin sits at the extreme end of low-noise digital clarity, but it is different from other low-noise digital designs because it doesn't use digital look-ahead. Therefore its response time is immediate, it adds no extra delay to the signal chain, and it works great for processing real-time performance effects. It uses no oversampling so there is no phase distortion or loss of high-frequency energy from anti-aliasing filters. It also uses no digital-style filters (FIR filters) and no digital look-ahead, so it adds no additional latency to the signal chain. Although it is not a model of an existing piece analog hardware, every component of its signal path is realizable in the analog domain. We think of it as a digital model of our ideal analog compressor: it could exist as an analog circuit but would be very expensive to build with physical analog electronic parts. The user interface is 100% scalable, designed specifically for iOS, so it looks beautiful at any screen size or orientation, from tiny portrait views in AUM on iPhone to the largest full-screen views on iPad Pro.

This is an AUv3 compatible visual effect plugin which is intended for use inside your favourite DAW such as Cubasis, Auria, Meteor, AUM etc. It will not function as a standalone app. Visual Compressor is a 4 band compressor/expander which has the ability to analyse audio in real time giving an accurate and reliable spectrum representation of your signal as well as visual feedback of compression or expansion levels. It's uses range from final mastering of songs to dynamic manipulation and EQing of drum tracks. What makes this different from a normal compressor is the ability to compress or expand frequency ranges rather than the whole mix, with up to 4 bands available. This allows you to say tighten up a wayward snare drum while adding that extra punch to the bass drum while leaving the rest of the track intact. Each of the 4 configurable frequency bands can be modified using drag and drop operations directly on the graph making it easy to understand and quick to configure. Turn on the labelling option for colour coded details. Each band can function as an EQ allowing raising and lowering the bands gain by +/-24dB. You can assign either a compressor or expander to each of the bands. The compressor allows you to compress excessively loud sounds that exceed a specified threshold. Each band has configurable attack, release and ratio settings. The expander can be used to expand sound exceeding the threshold while compressing anything below it. This makes it useful for adding dynamics or even for noise reduction of a specific band. Each band has mute and solo buttons so you can audition what is coming through a certain band, great for use during band frequency setup. There is also a bypass option which removes a band from use and reduces CPU load. You can load and save custom presets as well as copy and paste settngs between instances. This is great if you need to setup multiple instances with the same settings. One of the cool features is the ability to save up to 3 mixes and switch between them for comparision. These mixes are actually saved as part of custom presets and as the saved state in your DAW. This is the third of three products which will make up part of the 'visual' range of effects. Main Features: ○ 4 distinct frequency bands. ○ Assignable Compressor or Expander. ○ +/-24dB gain per band. ○ Assignable Q to control precise crossovers. ○ Spectrum Analyser with 'Pre' and 'Post' monitoring. ○ Vertical shift and scale options for the spectrum. ○ Mute and Solo buttons for each band. ○ Save & Compare up to 3 separate mixes. ○ Bypass option to remove a band and reduce CPU load. ○ Create and save custom presets. ○ Copy / Paste presets between instances. ○ Compressor / Limiter with Auto Makup Gain. ○ Twin VU meters with RMS/Peak display as well as peak and gate lights per band. ○ Brick wall limiter. ○ Quick Reset options for each section of the effect.
