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

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 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. No other referencing plugin does this.

Send it from the plugin

The snapshot menu sends the current snapshot, or any file you've exported from your DAW — WAV, AIFF, FLAC, OGG, MP3, up to roughly 15 minutes of stereo.

There in seconds, lossless

Audio is encoded to FLAC and uploaded in the background. Open sonescent.com/listen on your phone and it's already waiting — new uploads appear on their own, no refresh.

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.

Everything you need to finish the track.

Seven processing stages, drag-to-reorder, all transparent until engaged. Leave it on the master bus all session as a pure analyzer — engage the chain when you're ready to finish. Or flip to the External Rack (new in 1.2) and run your own VST3s inside Cartigraph's measurement — replace the chain or combine both engines, with the same gain-matched, sample-aligned before/after.

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+ — 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.
