A free psychoacoustic panning plugin that places a sound left or right by delaying one stereo channel by a fraction of a millisecond.
One central knob does the work, with steps down to a tenth of a millisecond, and it runs on macOS, Windows and Linux.
Best for: Vocals, Guitars, Keys & Synths, Sound Design. Genres: all genres.
Keywords: free, vocals, auto-pan, electric guitar, mixing, simple, single knob, synths, backing vocals, beginner-friendly, Linux, minimal controls, sound design.
What it does
Quick Haas is Venn Audio's "free and simple psychoacoustic panning plugin." Instead of changing the level of each side like a normal pan pot, it positions a stereo signal by adding a tiny delay between the left and right channels, using the precedence (Haas) effect.
- Single-knob control: a central knob moves the image left or right; most material needs only small settings under 2 ms.
- Fine resolution: delay adjusts in steps as small as a tenth of a millisecond.
- Stereo input: it works on stereo tracks, shifting the perceived position without the level loss of balance-style panning.
- Free and donation-supported: no cost; Venn Audio asks regular users to donate.
Version 2.1.0 was released in October 2025. It is free.

When to use it
Pick Quick Haas when you only need to nudge a part left or right by time rather than level, in a plugin with one knob. Kilohearts Haas and W.A. Production PsychoPan cover similar delay-based widening and placement with more controls, and Ozone Imager is the usual free choice for broad stereo width rather than placement.
- Best for: placing doubled guitars, synth layers and backing vocals in the stereo field without changing their level balance.
- Genres: any; it is a general mixing tool.
- Look elsewhere if: you need mono-compatibility checks, frequency-dependent width or modulation; Haas, PsychoPan or Ozone Imager offer more.
- Standout: sub-millisecond delay steps from a single knob, at no cost.
What producers say
The few user reviews are positive, with one reviewer pointing out that it works by channel delay rather than a true Haas effect.
- KVR users rated it 5/5 in both reviews; one (2018) called it "more a positioning tool" and said "the sound placement is clearly noticeable."
- Gripe: a 2022 KVR reviewer argued it "actually has nothing to do with the Haas-Effect itself," and the 2018 reviewer advised "some moderation" in use.
