iZotope Insight — Mac download

Insight 2 runs on any Mac with macOS Big Sur or later. It supports both Intel and Apple silicon processors natively, including arm64 AAX for Pro Tools 2023.3 and above.

Place Insight 2 on your master bus for loudness compliance and spectral balance checks. It monitors LUFS, true peaks and intelligibility in real time. Move it to a submix bus to catch problems in stems before they hit the master. On individual tracks, the spectrogram and vectorscope help verify stereo placement and frequency build-up. Resizable meters let you adapt the layout to a compact toolbar or a full-screen analysis panel. Colour signals flag issues as they happen, so you make decisions with visual confirmation alongside what you hear.

How Insight 2 compares with similar Mac metering tools

Three metering plug-ins dominate Mac-based post-production and mastering workflows. Each approaches the same core job differently.

iZotope Insight 2 vs. Waves WLM Plus

WLM Plus focuses on loudness and true-peak measurement with less spectral depth. It handles broadcast standards well, but the metering layout is fixed. Insight 2 gives you the 2D/3D spectrogram and surround scope on top of loudness tools — resizable and configurable to fit any screen layout. For dialogue intelligibility checks, Insight 2 pulls ahead. For a quick loudness read on a stereo mix, WLM Plus is lighter.

Insight 2 vs. NUGEN VisLM

VisLM is a loudness specialist built for compliance workflows. Its history graph and logging are more detailed than Insight 2's. But VisLM stops at loudness. Insight 2 adds spectral analysis, stereo field checks and a vectorscope in one window. If you need an all-in-one analysis station, Insight 2 covers more ground. If loudness logging is the only task, VisLM does that one thing deeper.

Insight 2 vs. Blue Cat's DP Meter Pro

DP Meter Pro is a customisable multi-channel meter with configurable thresholds and visual skins. It covers true peaks and RMS well. But it lacks the broadcast presets, intelligibility meter and Dolby Atmos 7.1.2 routing that Insight 2 includes out of the box. Insight 2 also integrates tighter with post-production standards. For sheer visual tweakability, DP Meter Pro wins. For compliance and diagnostics across multiple metrics, Insight 2 is the broader tool.

Workflow: verifying a mix for loudness compliance

1. Load Insight 2 as the last insert on your master bus.
2. Select the BS.1770-4 loudness preset from the preset manager tabs. This sets LUFS targets, true-peak limits and the loudness history graph to the correct standard.
3. Play the entire programme from start to finish. Watch the Integrated Loudness readout. Note any sections where the short-term LUFS drifts more than ±2 LU from the target.
4. Check the True Peak Meter. If the colour signal turns red, locate the overshoot point on the timeline and reduce the output ceiling of your final limiter.
5. Open the Loudness History Graph. Scan for sudden jumps or dips. These often point to a scene change in post-production where dialogue levels shift without enough fill.
6. Switch to the Stereo Vectorscope. Look for widening that pushes beyond safe limits — anything consistently outside the -0.5 correlation zone flags mono-compatibility risks.
7. If the mix is for broadcast, verify the short-term loudness maximum and the momentary loudness maximum against the delivery spec. Note the values.
8. Export a screenshot of the full Insight 2 window for the QC report and move on to the next deliverable.

What changed after version 2.4.0

• Native Apple silicon for Pro Tools — arm64 AAX support landed for Pro Tools 2023.3 and above. Users on M-series Macs no longer run Insight 2 through Rosetta inside Pro Tools sessions. Meter redraws feel snappier, and CPU usage drops noticeably on large Atmos projects.
• Preset manager with tabs — factory and custom presets got separate tabs. Switching between a broadcast loudness setup and a dialogue intelligibility layout now takes one click instead of scrolling through a flat list.
• Multi-user installation — studios and facilities with shared machines can install once for all user accounts. This cuts setup time on multi-seat Mac Pros and Mac Studios.
• Relay removed from the installer — Relay is no longer bundled directly. Users who relied on Relay for inter-plugin communication need to source it separately. Insight 2's metering routing still works via track and bus assignments without it.
• Authorization workflow changed — the method for activating the plug-in shifted. Returning users upgrading from older versions follow a different set of prompts than before.

• Native arm64 AAX support added — works with Pro Tools 2023.3+ on Apple silicon Macs
• Apple silicon install support now native
• Preset manager updated with factory and custom tabs

• macOS Big Sur or later
• Intel or Apple silicon Mac
