Nothing added to your audio path, drop it on any track and monitor in real time while you mix.
Overview
See the signal
Scope gives you a clear, accurate view of your signal in real time. Beat-synced or free-running, sharp at any size. Zero latency. Minimal CPU. If you find yourself wanting to compare two signals, isolate a frequency band, or measure a waveform, DeltaScope adds those capabilities.
- Beat-sync with 22 divisions, from 1/128th note to 16 bars
- Free-run mode for Hz and ms-based time windows
- Channel modes: Left, Right, Mono, Stereo
- Polarity-aware clip indicators, a waveform overlay and scope-border markers
- Manual sample or ms offset with a lock, to line the waveform up with the grid
- Adjustable phosphor-style glow, saved with your session
Beat-synced visualisation
Lock your waveform to the tempo for repeatable, stable views.
22 beat divisions from 1/128th note to 16 bars: straight, dotted, and triplet. PPQ-snap locks transients to the same position every cycle. Free-run mode available for Hz and ms-based time windows. If upstream latency shifts your timing, a manual sample or ms offset nudges the waveform back onto the grid and locks once you have it set.
Tempo-locked
Your waveform stays locked to the beat, every division from 1/128th note to 16 bars.
Stable views
PPQ-snap locks transients to the same position every cycle, no jitter, no drift.
Free-run mode
Switch to Hz or ms-based time windows when you don't need tempo sync.
Amplitude scaling
Scale the display from -36 dB to +36 dB to focus on the detail that matters.
Clean, accurate display
Full visual quality from the DeltaScope rendering engine.
Custom waveform colours. Adjustable phosphor-style glow. Polarity-aware clip indicators. Resize the window to any size, the display stays sharp and responsive, up to 4K.
Colours and glow
Set your waveform colour to match your workflow, and dial in CRT-style phosphor glow from clean to full. Both are saved with your session.
Clip indicators
A clip overlay marks overs on the waveform, and clip markers light the scope border, polarity-aware, top for positive and bottom for negative. Toggle either in the settings cog.
Full screen to 4K
Drag the window to any size. The display redraws cleanly at every resolution, up to 4K.
Channel modes
Left, Right, Mono, or Stereo, switch instantly.
Support
Zero fluff (no-nonsense)
Compatibility
VST3 and AU. macOS 13 Ventura or later, Intel and Apple Silicon native.
No strings
Free to keep. No trial, no feature gates. Activate with a free licence key, no dongle, no iLok.
Support
Direct email support. Feature requests welcome.
Coming soon
Windows, AAX, and CLAP support are on the way.

Need deeper analysis?
Scope shows the signal. DeltaScope analyses it.
DeltaScope is our audio analyser plugin, built on the same engine: null test any two signals, isolate and hear the difference, map phase correlation across time, and measure straight from the waveform.
