## What is Scope AUv3 Visualizer?

Get professional audio visualization with your AUv3 host or the standalone app. Scope transforms your audio into stunning visual displays using GPU-accelerated graphics with classic phosphor glow effects reminiscent of vintage CRT oscilloscopes and more.

Featuring Scope Linear, Scope Circular, Flurry particle, Spectrum, Spectrogram, Spectrum Equalizer, 3D Spectrum, Semaphore and Sliding Scope visualization modes with single and multi-channel split view. Multiple color schemes (including classic phosphor green, vibrant 80s Red and Rainbow) with smooth transitions. Flurry mode renders mesmerizing smoke-textured particles with audio-reactive dynamics, inspired by the classic screensaver. All visualization modes are fully automatable parameters in your DAW.

Optimized for HiDPI Retina displays with dynamic line width scaling, Scope delivers smooth 60fps+ performance for live performances, creative sound design and professional audio monitoring. Whether you are analyzing dynamics during mixing, assisting with sound synthesis or adding visual interest to your sessions, Scope provides the precision and aesthetic flexibility you need. Place it anywhere in your signal chain to visualize audio at any point, though it is typically used last to analyze the cumulative effects of your processing chain.

## Key features

- Classic phosphor glow effects

### 2/5 — Doesn’t work as an AUv3 plugin on IPad.

*2026-06-27*

Looks cool, but I go to find the documentation, it doesn’t exist on the developers website. No support, doesn’t appear in GarageBand, even after reboot.

### 1/5 — This app sucks.

*2026-03-10, version 2.4*

It just does.

### 5/5 — Lovely

*2026-02-08, version 2.3.1*

Thanks for such a tool!

### 1/5 — Needs triggering

*2025-12-19, version 2.0*

This "scope" would be much more useful if it implemented some form of triggering. Even a simple sine wave just keeps rolling around when it should be stationary.

### 1/5 — No controls = useless

*2025-08-22, version 1.7*

Hard to believe they published this.

### 5/5 — Гуд!

*2022-06-02, version 1.1*

Вариант AUv3 осциллографа. Конечно анализатор он не заменит, но для тех, кто занимается синтезом звука, видеть формы волны может быть весьма полезно.

### 4/5 — Thanks

*2021-11-15, version 1.1*

Thank for such a handy tool. Can you please add ability to scale time. Just to see more over time

### 5/5 — Does exactly what I want it to do

*2021-11-02, version 1.1*

Looking for an oscilloscope to understand what is happening when I’m playing different waves on my synth and found this. Great app and price. 5 out of 5.

### 5/5 — Exactly as described

*2021-05-26, version 1.0*

Simple and effective/useful oscilloscope. Works perfectly.  Exactly zero frills!

One frill I’d welcome: some demarcations for input level relative to 0db.

### 5/5 — Full screen visualizer on my iPad!

*2021-02-07, version 1.0*

Just lean your iPad on a speaker (or place elsewhere) and watch the show!  Pure visual display with no indication of any app running.  No controls visible!  Just amazingly designed.  Must be the best $.99 I ever spent...yup!

## Version history (last 5 releases)

### 3.1 — 2026-08-09

New Sliding Scope view with OpenGL rendering and continuous scroll, plus Split View for per-channel rows across all pages.

### 3.0 — 2026-08-01

Five new views join the oscilloscope. Spectrum and Spectrogram analyse the signal on a background thread, Spectrum Equalizer shows eight octave bands on a vintage LED-style display, 3D Spectrum draws an FFT waterfall you can rotate with a drag, and Semaphore lights three lamps from the lows, mids and highs.

A hamburger button now opens a native menu with every view, zoom preset and colour scheme at the top level, replacing the old drawn config panel.

All views share the vertical zoom parameter for input gain and the same colour schemes, including animated Rainbow. The 3D view's render style, auto-rotate and rotation speed are automatable, and its angles are saved with the project.

Fixed Flurry stuttering after long sessions, and fixed the menu button staying hidden after a menu selection.

### 2.5.1 — 2026-07-22

Fixed jagged, step-like breaks in the waveform for a clean, continuous line.
Smoother animation that now adapts to your screen's refresh rate, taking full advantage of 120Hz ProMotion displays.

### 2.5 — 2026-05-03

Stereo linear mode now overlays L/R on the full canvas for a clearer view.
Smoother waveform with frame-to-frame lerp and asymmetric transient response (linear and circular modes).
Thicker waveform core and beefier glow on hot signals.
Editor window size is now persisted between sessions.
Fixed a crash when the GL context wasn't ready yet.

### 2.4 — 2026-02-22

Redesigned waveform rendering with smooth triangle-strip ribbons and tapered end caps.
Added frame-to-frame interpolation for fluid, jitter-free waveform animation.
Auto-detecting stereo mode with left/right channel split display.
Circular mode: animated zoom tunnel trails.
Flurry mode: improved audio responsiveness with asymmetric attack/decay and peak detection.
Optimized GPU rendering path across all visualization modes.
Fixed circular waveform seam alignment with amplitude changes.
Resolved cross-thread data race in waveform buffer updates.
Improved high-DPI rendering with wider, more visible waveform lines.
Reduced visual noise in glow ribbon width and opacity.
General rendering stability and performance improvements.
