Cartigraph main view: loudness over time and per-band levels comparing your mix, a reference and a snapshot, loudness-matched

Watch Cartigraph work on a real mix

Ten minutes on loudness bias: why the louder version always wins, and how snapshots and loudness-matched comparison give you a fair listen.

Comparison

Your mix. Your reference. Your past self.

Switch between your live mix, a reference track, and a saved snapshot in one keystroke, loudness-matched so you're judging tone, not volume. BLIND mode randomly assigns mix vs. snapshot to two unlabeled buttons: pick the one that wins, then hit Reveal. ABX mode runs a significance test and tells you whether you can actually hear the difference, or whether you're guessing. No more "louder = better" fooling yourself.

Cartigraph Blind Compare after Reveal: the version picked blind turns out to be the current mix, loudness-matched against the snapshot
Snapshots

Version control for how your mix sounds.

Save a snapshot before any risky move. Cartigraph freezes up to 3 minutes of any section of your mix (no bouncing, no re-importing) and stores it with your DAW session so it comes back when you reopen the project. Pull any of up to 32 snapshots up against your current mix or reference, instantly, and see the difference spectrum: exactly where energy moved between revisions instead of eyeballing two overlapping curves.

Cartigraph difference spectrum: since Snapshot 6 the mix has less around 200 Hz and more top end
Cartigraph Listen

Your mix on your phone, seconds after you touch it.

Every license includes Cartigraph Listen: a private listening library that syncs straight from the plugin to your phone. Send the snapshot you're working on, or any track you've exported, and hear it on earbuds, in the car, on the kitchen speaker. No bouncing to a folder, no AirDrop, no Dropbox link.

Cartigraph Listen library on iPhone: a reference track and two snapshots with dates, lengths, and LUFS readouts
Your snapshots and references, synced to your pocket, each with its length and LUFS.
Cartigraph Listen compare view: a mix and a snapshot loudness-matched, with big A and B buttons
A/B any two versions right on your phone, loudness-matched so louder can't win.
Cartigraph Listen listening view: loop, markers, and a time-stamped review note tagged with the listening system
Loop a section, mark a moment, and leave time-stamped notes tagged Car, Headphones, Phone, or Speakers.

Analysis

See exactly what's different between your mix and theirs.

Five analysis views (spectrum, dynamics, stereo image, correlation, and spectrogram), all with simultaneous MIX / REF / SNAP overlay in colour-coded channels. The loudness arc plots short-term LUFS across the entire track as it plays, so you can confirm your drop actually hits harder than the build. Resonance detection flags the frequencies that ring and build over time. Click any flag to audition it.

Cartigraph EQ after Analyze: four resonance flags on a chorus, mid-channel cuts on two of them, and the 306 Hz flag reading +6.0 dB over the surrounding octave
Cartigraph Suite

Everything you need to finish the track.

The Suite adds seven processing stages, drag-to-reorder, all transparent until engaged. Leave it on the master bus all session as a pure analyzer, then engage the chain when you're ready to finish. Cartigraph includes the dynamic EQ and a simple true-peak limiter from this list, for checking a mix at a mastered level.

Dynamic multiband

Click the spectrum to drop a band that compresses only its own frequency range. Up to 8 bands with imaging tools: mono-maker, M/S solo, and mono-safe width cap.

Glue compressor

Classic VCA bus compressor with side-chain high-pass, parallel mix, and switched ratios. Binds the mix without killing the kick.

Dynamic EQ

Up to 24 bands. Any node can move only when the signal crosses a threshold. Per-band M/S/L/R placement. Resonance detection built in.

Saturator

Five characters (Soft, Tube, Tape, Transformer, and Tape Machine) with drive, mix, bias, tone, and a high-pass to keep the low end clean. 4x oversampled.

Smooth

28-band dynamic resonance suppressor. Tames harsh frequencies before the clipper emphasises them. Reduction hard-capped at 12 dB per band so it can't dull a master.

Clipper

Transparent peak control before the limiter. Soft, Hard, and Distort modes, draggable threshold line, up to 8x oversampling.

True-peak limiter

Brickwall limiter with lookahead, inter-sample peak handling, gain match, and reference loudness matching. Draggable ceiling line.

Dither

TPDF dither with optional 2nd-order noise shaping, always last in the chain. For 16 / 20 / 24-bit export.

External Rack · Cartigraph Suite

Run your own plugins inside the measurement.

Eight slots for your favorite VST3s, hosted inside Cartigraph Suite. Put your go-to EQ, compressor, or limiter before or after the built-in chain, or replace the chain entirely. Everything you load gets the same gain-matched, sample-aligned before/after, shows its cost per slot, and is captured by snapshots like everything else. Drag cards to reorder. Dither always stays last.
