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.

AudioScope is an invaluable audio plugin for mixing and mastering with a toolbox of additional mixing aids. It was originally created as a method for comparing your mix to a reference track and seeing exactly what frequencies to tweak in order to obtain a desired match. This alone is incredibly useful for creating the feel of a particular genre of music, by tweaking your mix to match. AudioScope is so much more than this! It includes a great visual mixer which enables you control your entire mix from a single window inside your DAW. You see a top-down visualisation of your entire mix and stereo balance. You can save up to 3 compare mixes and quickly switch between them. You can also save up to 12 snapshots of stereo positions and levels, then morph between them. All of this functionality is available via MIDI, so with one simple CC command, you can switch out one mix for another or engage a snapshot. You are able to group your drums and other elements so that the mix doesn't become overwhelming, allowing you to focus on a subset of key elements if you wish. AudioScope also includes a suite of tools to adjust EQ, compression, and overall balance of your mix. The way AudioScope works is unique, with a quick and easy workflow: Insert an instance of AudioScope on each of your track's Insert Effect slot and name the track. Now simply open one of the instances and you have the ability to control all tracks from a single window. AudioScope is equiped with its own shelf and peak filters, EQ and lookahead compressor (with Sidechain). You can find demonstrations and tutorials for this and all my apps on the 'Paul the MusicMan' YouTube channel. Features: ○ Take control of your host DAW using a single simple interface. ○ Compare your master mixes frequency response to a reference track for a given genre. ○ Compare tracks to see which frequency ranges are problematic graphically. ○ Control your DAW's entire mix from a single 2D live mixer. ○ Change the EQ of each track quickly and easily from a single window. ○ Includes the ability to add low and high shelf filters to each track. ○ Add up to 3 parameteric EQ's to each track to cut or boost frequency ranges. ○ Enable the internal look ahead sidechain compressor. ○ Capture up to 3 compare mixes and preview in real time. ○ Create up to 12 snapshots and fade from one to another. ○ Invert the phase of tracks to avoid phasing issues. ○ Remove DC option to remove unwanted noise and rumble below 60Hz. ○ Instant Pass Thru to bypass all instances of AudioScope. ○ Mix lock to prevent accidental changes to your mix. ○ Monitor up to 32 tracks at once.
