Prisma Suite icon — a prism refracting a spectrum

Deish.Audio · Windows · VST3 + Standalone

Five analyzers. One window.

Spectrum, spectrogram, oscilloscope, goniometer and the full BS.1770-4 loudness suite on one screen — for producers, DJs and engineers who would rather read one window than open four plug-ins. It is a pass-through analyzer and never touches your audio.

Panel by panel

The five analyzers

A header of global controls, then the analyzers: spectrum across the top, oscilloscope and goniometer below it, level and loudness metering down the right edge. Every divider drags, every panel has its own gear, and the arrangement is saved with your session.

01 — Spectrum

Spectrum with musical-note readout

A smooth FFT curve or up to 320 log-spaced bars, with attack/release smoothing so it reads "fast up, slow down" instead of flickering. Hover anywhere and it tells you the frequency, the level, and the musical note — with the key lit on the piano strip along the axis. Capture a reference curve and view the difference against it.

  • FFT size 512 – 16384, perceptual tilt, adjustable dB range
  • Colour by frequency, by energy, or one FLAT colour everywhere
  • Reference curve overlay with difference view
  • Peak-hold history and a FabFilter-style dB scale

02 — Spectrogram

Multi-resolution spectrogram

Three FFT sizes crossfaded, so the low end stays detailed while transients stay crisp. Each frame writes one column into a circular image, which is what makes it scroll smoothly rather than step. Run it in place of the spectrum, or side-by-side with its own draggable divider.

  • 32768 / 8192 / 2048 FFTs, PSD-normalized, seamless crossovers
  • Frequency scale: Log · Linear · Mel
  • Palettes: Magma · Ice · Fire · Aurora · Mono
  • dB floor, low/high bias, and freeze to hold a passage still

03 — Oscilloscope

Oscilloscope with band-split colour

Two modes. Sync triggers on a zero crossing and draws the raw waveform, for checking phase and transient shape. Scroll renders a min/max envelope into a scrolling image, split into low, mid and high bands and coloured accordingly — the DJ software view, where a kick is red, a vocal is green and hats are blue.

  • Time window 10 ms – 5 s (3 s default)
  • Whole-pixel scroll accumulator — jitter-free at any window
  • Peak-history overlay, anti-flicker envelopes, mirrored fill

04 — Goniometer

Goniometer with correlation metering

Left and right rotated 45° and drawn as a connected curve into a phosphor-persistence image — a vertical smear means centred, a horizontal one means wide, and a diagonal lean means one side is louder. The correlation rail underneath is the early warning: if it swings negative, something is going to disappear when a club sums to mono.

  • Modes: Lissajous · Polar Sample · Polar Level (Peak / RMS / Envelope)
  • Persistence, dot size, guides, and normalize (off by default — true levels)
  • Correlation meter from −1 to +1, updated every frame

05 — Levels & loudness

Broadcast-grade loudness metering

bx_meter-style Peak and RMS bars with a floating crest segment, peak-hold and over lights — plus the full broadcast loudness suite underneath. Pick a platform in the header and the target line appears; go over and it turns red. Loudness runs on the audio thread and is published through atomics, so the readouts are honest at any buffer size.

  • LUFS Momentary / Short-term / gated Integrated (ITU-R BS.1770-4)
  • True Peak in dBTP, 4× oversampled · LRA (EBU R128, P95−P10)
  • PLR / PSR and Mid/Side maxima
  • Targets: Spotify · YouTube · Apple · Tidal · Amazon · Deezer · Club · EBU · ATSC
  • K-System scales (K-20 / K-14 / K-12) and an analog VU with settable 0 dB reference

Panels 01, 03, 04 and 05 are real captures of the window running. Panel 02 and the MINI strip below are still drawn live in your browser rather than photographed; each of those is stamped Illustration, so you always know which you are looking at.

Standalone & MINI

Runs without a DAW, and gets out of the way

The standalone app listens to whatever your PC plays — referencing on Spotify, checking a bounce, streaming, DJing. No routing, no virtual cables. Then press MINI and all five analyzers collapse into a strip you can pin above your session and forget about.

  • System-audio capture (WASAPI loopback), on by default
  • Follows your default output device automatically
  • MINI strip for a second monitor or the top of your screen — state persists

Focus & channel

Band-zoom every analyzer at once (Low / Mid / High) and audition Stereo, Mid, Side, L or R from the header.

Themes & presets

Six themes and eleven presets, including Dual View, Broadcast and Low End.

Your layout, kept

Every divider drags and every panel has its own gear. The arrangement is saved with the session and restored when you open it.

Who it is for

Three rooms, one window

Producers

Your room is lying to you

Untreated rooms hide low end and exaggerate the top. The spectrum shows what is actually there, the goniometer's correlation rail catches the wide synth that disappears on a phone speaker, and the LUFS readout tells you where the track will land on Spotify before you upload it.

DJs

Check a track before it checks you

The standalone listens to whatever is playing, so you can run a promo through it straight from your browser. Over-limited masters show up instantly as a flat oscilloscope and a PLR under about 8, and MINI mode keeps all five meters in a strip above your library.

Engineers

Deliverables that pass first time

Integrated LUFS, LRA, and 4× oversampled True Peak to ITU-R BS.1770-4, with platform and broadcast targets in the header. Capture a reference curve, switch to difference view, and see exactly where your mix departs from it.

Under the hood

How it is built

Real-time safe by construction

No allocation, no locks, no file access in processBlock. Audio reaches the display through a lock-free ring buffer, and the GUI does the heavy FFT work on its own thread. Five analyzers therefore cost one instance of CPU, not five.

Bit-transparent by default

The signal that arrives is the signal that leaves. The one exception is opt-in: selecting Mid, Side, Left or Right in the header auditions that channel, which is the purpose of the control.

Written to the standards

K-weighting filters, 400 ms Momentary and 3 s Short-term windows, gated Integrated loudness, 4× oversampled True Peak, and an LRA histogram with the −70 / −20 LU gates, implemented to ITU-R BS.1770-4 and EBU R128.

Offline licence verification

Activation is a single signed call. After that the plug-in verifies an RS256 signature against a public key compiled into the binary, so the licence server is never in the critical path of a session and an offline studio opens normally.

Trial & licence

Try it for 30 days. Then it's $10.

No account, no subscription, no dongle. The trial is the complete plug-in — nothing is disabled, nothing is muted, no noise is injected.

Install and run

Unzip, run the installer, rescan your plug-ins or launch the standalone. Your 30 days start on first run and the countdown sits in the corner of the window.

Buy when you're convinced

$10 through Stripe. Your serial arrives by email within seconds — a lifetime licence for up to three machines, no renewal.

Activate in place

Gear icon → MAIN → Activate…, paste your email and serial. Nothing to reinstall, nothing to re-authorise, and a plug-in already open in your DAW picks it up within a couple of seconds.

What happens at day 30 if you don't buy? The analyzers stop and the window says so — plainly, with the activation button still reachable. Nothing is deleted, no session is broken, and activating later brings everything straight back.

Release notes

What changed

Current

v0.22.0 — trial + in-app activation

  • Activate from inside the plug-in: gear → MAIN → Activate…
  • Licences verify offline on every launch (RS256, Windows CNG)
  • The 90-day beta window became a 30-day trial; a licensed install ignores the clock entirely
  • Activation is picked up live — an open plug-in notices within ~2 seconds
  • The gear stays clickable when the trial expires, so activation is always reachable

Previous

v0.21.0 — compact mode

  • MINI: every meter collapses into a full-width strip, state persists
  • Spectrum and spectrogram side-by-side with their own divider
  • Three new presets — Dual View, Broadcast, Low End
  • Light theme reworked; header controls aligned on one baseline
  • Fixed a standalone crash entering compact mode

Questions

Questions

Does it change my audio?

No. Prisma is a pass-through analyzer — what goes in comes out, bit for bit. The single exception is opt-in: choosing Mid, Side, Left or Right in the header auditions that channel, which is the entire point of the control.

Is the trial limited in any way?

Only in time. All five analyzers, every theme, every preset, both formats. After 30 days the analyzers stop until you activate a licence.

What does $10 actually buy?

A lifetime licence for Prisma Suite on up to three of your machines, including future 0.x updates and 1.0. No subscription and no renewal.

I bought a new computer — am I stuck?

Three machines is a soft limit, not a trap. Email us and we'll clear the slot from the old one; the licence itself never expires.

Does it need an internet connection?

Once, to activate. After that the licence is verified locally against a public key compiled into the plug-in, so an offline studio opens normally.

Why does Windows warn me about the installer?

It isn't code-signed yet — a certificate is a running cost we're taking on at 1.0. Until then SmartScreen shows a warning on any new publisher's installer; choose More info → Run anyway.

Mac version?

Next on the list, as AU and VST3. The DSP and GUI are already portable; it needs a build machine and notarization.

Which DAWs are supported?

Any Windows VST3 host — Ableton Live, Reaper, FL Studio, Cubase, Studio One, Bitwig and friends. The standalone needs no host at all and listens to your system output.
