WaveWarp is a live drawing board for audio: drag blocks onto a canvas, wire them together, and the sound flows through your chain in real time — one sample at a time. The same idea, from a 1998 classic to a modern, cross-platform revival.
Every block does one thing to sound — read a sound card, apply an effect, mix, measure, record. The cable between two blocks is the audio flowing from one to the next. You literally draw your own signal path, and you hear it run in real time as you build it.
Under the hood, WaveWarp processes one sample at a time. That is what makes true, sample-accurate feedback loops possible — and it has been the beating heart of WaveWarp since day one.
Every block wears its type as a colour, and every cable its signal — the same convention as the app:
WaveWarp began as a commercial Windows product from Sounds Logical, went quiet for two decades, and came back rebuilt from the ground up.
Yusuf Jafry and Pepijn Sitter began building WaveWarp in 1998 under their company Sounds Logical. A Windows workbench and a DirectX effect host in one, it shipped with a Component Library of effects, a live message window, transport controls and parameter windows — and it earned an Electronic Musician 2001 Editors' Choice.
The Component Library on the left, a hotkeys window, a transport window, the drawing board, and floating parameter windows for every block. It looked like Windows 98 — because it was.
A WAV input fanned into a down-sampler, a delay and an up-sampler, then merged and played out — mixing sample rates on one board. Different chrome, identical concept to the board at the top of this page.
Before VST took over Windows, the way a plugin got into Sound Forge, Cool Edit, Cakewalk or WaveLab was DirectX — Microsoft's DirectX Media Objects. WaveWarp could hand any board to such a host through two dedicated I/O blocks, and shipped a whole folder of boards pre-converted to prove it. Those boards said so themselves, in capitals, in their own on-screen description: any drawing board at all could be a DirectX plugin, not just the ones in that folder.
DirectX audio plugins no longer exist. The format was superseded and the hosts moved on, so those boards became a category about a format instead of about sound — and in 2026 WaveWarp retired them. The promise itself survived intact: the modern build ships a VST3/AU plugin that hosts a complete board, and inside a DAW its input and output blocks bind to the host's bus. Any board is still a plugin; only the letters on the socket changed.
Sounds Logical wound down and WaveWarp went dormant. The source survived — and the core idea kept its pull.
On 30 July 2026, Pepijn pulled the original source out of storage and started WaveWarp 3.0. One modern C++ engine now drives the same core into three homes: the cross-platform DrawingBoard desktop app, a full VST3 / AU plugin that drops a whole board onto a track in your DAW, and a mobile player on Android. The workbench was redrawn from scratch — a searchable node library down the side, an Inspector for the selected block, blocks grouped by category and colour, and a clean light/dark theme. A free account keeps your boards and impulses in the cloud, so the same board plays everywhere.
Everything the original could do, plus the things a modern machine — and a phone — make possible.
The per-sample core is intact, so feedback loops behave exactly right — no block-processing shortcuts.
Record from one interface and play out of another — different clocks and sample rates on one board.
Cables carry a bus, not just one channel. Split, process and merge from mono to surround.
WaveWarp runs as a complete VST3 / AU plugin: drop a whole board onto a track, wired to the host's audio in and out, and shape it like any other effect.
Bundle a busy patch into one tidy block, dive in to edit, pop back out — wiring intact.
Boards and impulses live in your account and autosave. Draw on the desktop, play the same board on your phone. Sign in through your browser — and a signed-in machine keeps working offline for a month.
Sound you can draw, and hear in real time — processed one sample at a time — now open where the original was closed, on every device you own.
Every example DrawingBoard — from single effects to whole synths and live-input rigs — with a real screenshot, the effects it uses, whether it plays on the mobile app, and how the original documented it back in 1998.
The whole WaveWarp effect library — delays, reverbs, filters, dynamics, modulation, signal generators and the control-rate math that drives them. Each block shows what it does, its parameters, the boards it appears in, and — where we still have it — its original 1998 icon.
Draw on Windows with the DrawingBoard app or the VST3 / AU plugin in your DAW, and play the boards you draw straight from your phone. A free account ties them together.
