PhaseII Dual Stereo Phaser Plugin (AUv3) PhaseII is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro, GarageBand or AUM. Overview PhaseII is a dual stereo phasing machine with a vintage vibe! As well as traditional super-wide stereo phasing effects, PhaseII can also produce all manner of swirly modulated goodness by running the independent phasing engines in parallel or series. Selectable modes allow quick access to finely-tuned settings under the hood that "just work", from subtle to extreme - just the thing if you find some phasers to be overly complex with too many parameters! Set Rate and Depth to taste, adjust the stereo Width, then you can even add some gritty Drive for some "analog" warmth. Controls Active - Bypasses the effect (Off) or selects one of the following processing modes: Stereo - Two independent phasers for the left and right channel, with LFOs 90 degrees out of phase for a stereo effect, determined by the Width control. Parallel - Two independent stereo phasers for the incoming audio, which are then summed together at the output stage. The LFOs for each of the four phasers are 90 degrees out of phase for a stereo effect, determined by the Width control. Series - Two independent stereo phasers with Phase I processing incoming audio, which is then passed on to Phase II for a double-helping of phasey goodness at the output stage! This is potentially the most dramatic phasing effect, especially with the Width set to maximum as each of the four phaser LFOs are 90 degrees out of phase. The following controls apply to each phase stage, referred to as Phase I or Phase II: Phase I/II - Toggles the Phase I or Phase II processing engine On or Off. Rate - Sets the rate of the phaser LFO in Hz. Depth - Sets the depth of the phase effect. Mode - Selects one of four different modes. Each mode configures several "under the hood" settings - think of each mode as a mini preset for internal parameters. Modes range from subtle (I) to extreme! (IV). The following controls are global: Width - Adjusts the stereo width from super-wide to monophonic. Note this only adjusts the "wet" phased sound so your original stereo image remains intact for the "dry" signal. Drive - Applies an optional amount of warm overdrive to the phaser processing only, for a bit of a vintage vibe! Mix - Balances the processed audio with the incoming / dry signal. At zero, the output is totally dry, and at 100%, the output is totally wet and phased to the max! The phasing effect can sometimes create loud resonant frequency peaks that could result in clipping. To protect against this, soft limiting is applied at both the phasing processing stage and at the final summed output. If the input levels are high, this can add to the "analog" like sound of PhaseII when compression and saturation occurs. About The UI Not everyone likes the UIs of my latest (2025) plugins - I get it. However, the simplistic and generic approach allows me to (a) 99% focus on the DSP, sound quality and CPU performance, and (b) significantly reduce the development (and potential maintenance) time, which is reflected in my pricing.
