Every feature, in depth

Cartigraph is built around one question: is it actually getting better? Snapshot how your track sounds now, keep working, then compare against where you were — always loudness-matched, so you're hearing real change instead of just a louder version. Everything else — reference, deep analysis, a full finishing chain — surrounds that loop. Here's the full tour.

Snapshots

Version control for how your mix sounds

This is the heart of Cartigraph. Freeze how your track sounds at any moment, keep working, then put that snapshot up against your current mix — always loudness-matched. It's the difference between thinking you improved it and knowing you did.

Freeze a moment. Compare it for real.

Freeze up to 3 minutes of any section of your mix — no bouncing, no re-importing — and keep up to 32 snapshots stored with your DAW session. Pull any of them up against your current mix or a reference and A/B in real time. A mastering engineer can run the finished master against the untouched snapshot as it plays; a mix engineer can check this pass against the last one; a producer can hear exactly what a change actually did.

New in 1.2 — The External Rack

Your favourite plugins, inside Cartigraph's measurement

Click EXT and the processing section flips to an eight-slot rack that hosts your own VST3 plugins. Everything around it — snapshots, reference comparison, gain-matched bypass, Blind Compare — keeps working exactly the same, whoever's processing is in the middle.

Replace the chain, or combine both

Three modes: REPLACE CHAIN hands the whole processing section to your plugins. BEFORE CHAIN and AFTER CHAIN run both engines in series — EQ in Cartigraph and finish with your favourite limiter, or drive a third-party saturator into Cartigraph's mastering chain. Latency is reported to your DAW exactly, and dither still runs last. The controls stay honest too: EXT shows the rack, the rack's own ON/OFF runs it — so you can stage a chain in silence and bring it in at once.

Cartigraph External Rack in AFTER CHAIN mode — four third-party VST3 plugins loaded with live CPU and latency readouts

The before/after you can trust — for any plugin

BYPASS stays sample-aligned and GAIN MATCH drops the processed output to the raw mix's loudness, so you judge what a plugin does — not how loud it makes things. It's the same honest A/B Cartigraph applies to its own processing, now wrapped around anything you own.

The plugin shootout

Master with Cartigraph's chain and record a snapshot. Flip to the rack and build the same intent with your third-party chain. Then Blind Compare — loudness-matched, label-free, your ears against the labels. Whichever wins, you learn something true.

Built like a host should be

Scanning probes every plugin in a separate worker process, so a badly-behaved plugin can't take your DAW down — and the list is remembered, so you scan once. Type to search, drag cards to reorder the chain, drop a .vst3 straight from Explorer, and watch each slot's CPU and latency live. Sessions restore every guest with its exact settings; a plugin missing on another machine is preserved, not lost.

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. No bouncing to a folder, no AirDrop, no Dropbox link. No other referencing plugin does this.

Send a snapshot, or the whole song

In the snapshot menu, Send Snapshot to Listen uploads the snapshot you're working with. Send Audio File to Listen… takes anything you've exported from your DAW — WAV, AIFF, FLAC, OGG, or MP3, up to roughly 15 minutes of stereo — so a full song is one export away, and you don't need a snapshot at all.

It's waiting before you pick up your phone

Audio is encoded to lossless FLAC and uploaded in the background — the status line under the meters reads Sending…, then Sent. Open sonescent.com/listen and it's already there. New uploads appear on their own within seconds; nothing to refresh, nothing to sync by hand.

Sign in once, then forget about it

Enter the email on your license and tap the link that lands in your inbox. You stay signed in for 30 days, and the session quietly renews itself every time you use it. Add the page to your home screen and it opens like an app from then on. A native iOS and Android app is in development.

Hear it on the systems that tell the truth

Earbuds, the car, the kitchen speaker — where you find out what your mix actually does. Your library keeps a rolling window of the 30 most recent uploads, so older ones fall off by themselves and it never needs housekeeping. Everything is lossless end to end and private to your license. Because uploads are tied to that license, Listen needs an activated one — it isn't part of the trial.

Who it's for

For producers, mixers, and mastering engineers who don't want to guess.

Cartigraph lets you snapshot, compare, and loudness-match every version of your track, so you can judge what actually changed — not just what got louder.

The producer

You want to know if the track is actually getting better. Capture a rough idea, push the sound or arrangement, then compare it instantly against where you started — no guessing, no second-guessing, and no "I think this is better."

The mix engineer

You need proof that the mix is moving in the right direction. Use snapshots, dynamic EQ views, spectrum overlays, and reference comparisons to hear what changed, identify what still needs work, and confirm every move against your last pass.

The mastering engineer

You need to compare the finished master against the unmastered mix without being fooled by level. Cartigraph keeps the comparison loudness-matched in real time, so you can judge tone, width, punch, and translation — not just volume.

Reference & compare

Judge your mix against pro tracks — and your past self

Switch between your live mix, a reference, and a saved snapshot in one keystroke, always loudness-matched so you're hearing tone, not volume.

Loudness & dynamics over time

Short-term LUFS plotted across the whole track, plus per-band level for mix, reference, and snapshot together — confirm your drop actually hits harder than the build, and see where your dynamics differ from the track you're chasing.

Mix vs. reference vs. snapshot, overlaid

All three spectra at once in colour-coded channels — see exactly where your low end, mids, and air sit against your reference and your previous revision.

BLIND A/B

Hides which is which behind two unlabeled buttons. Pick the one that wins, then reveal — it kills the "louder = better" and "mine = better" bias that wrecks mix decisions.

ABX significance testing

Runs a real statistical test and tells you whether you can actually hear the difference between two versions — or whether you're just guessing.

Analysis

Five analysis views, all reference-aware

Every view overlays mix, reference, and snapshot in colour-coded channels.

Stereo image

Width per frequency band, so you can widen with intent and keep the low end mono.

Correlation

Phase correlation across frequency and time — catch mono-compatibility problems before they reach the master.

Spectrogram

A full spectrogram of mix, reference, or snapshot — spot resonances, masking, and noise across the entire track.

Finishing chain

Seven stages, drag-to-reorder, transparent until engaged

Leave it on the master bus all session as a pure analyzer — engage the chain when you're ready to finish.

Dynamic multiband

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

Glue (bus) compressor

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

Dynamic EQ

Up to 24 bands that only move when the signal crosses a threshold, with per-band M/S/L/R placement and built-in resonance detection.

Saturator

Soft, Tube, Tape, Transformer, and Tape+ characters — with drive, mix, high-pass, bias, and tone. 4x oversampled.

Smooth

A 28-band dynamic resonance suppressor that tames harsh frequencies before the clipper emphasises them — reduction is hard-capped at 12 dB per band, so it can't dull the master.

Clipper

Transparent peak control ahead of the limiter — Soft, Hard, and Distort modes, a draggable threshold line, and up to 8x oversampling. Distort's CHARACTER knob sweeps clean to smashed and is level-compensated, so it changes the sound, not the volume.

Cartigraph clipper

True-peak limiter

Brickwall limiter with lookahead, inter-sample peak handling, gain match, and reference loudness matching — plus dither on export.

Workflow

Built for real sessions

Project notes

Keep mix notes and to-dos right inside the plugin — they save with your project so they're there when you reopen it.
