About
About Outboard
Outboard is an independent audio-software studio. We build Outboard-EQ and Outboard-Slab: two plugins for different moments in the mixing and mastering workflow. Outboard-EQ folds dynamic EQ, spectral resonance suppression, analog character and true-peak/LUFS metering into an 8-band mastering equalizer. Outboard-Slab is the fast fattener for density, color and commit — three macros up front, a multistage engine underneath. Both are engineered around modern DSP rather than skeuomorphic gimmicks.
Two plugins, one principle
Outboard-EQ was built to fold the long mastering chain of parametric EQ, dynamic EQ, de-essing, resonance suppression, saturation and metering into one phase-coherent window. Outboard-Slab follows the same idea for fast mix decisions: density, color and parallel mix without a plug-in stack and without level guesswork. Different tools, same direction — fewer detours, more control over the signal.
Under the hood
The depth is in the DSP, and in both plugins we'd rather show it than hide it:
- Outboard-EQ uses a shared STFT engine (4096-point FFT, 75% overlap) for Soothe-style per-bin resonance suppression — running only on bands that need it.
- Linear-phase EQ built from frequency-sampling FIR filters with Kaiser windows, in three resolution tiers, plus an atomic IR double-buffer for phase changes during playback.
- Outboard-Slab puts saturation, compression, color, loudness compensation and a clean output ceiling behind the FAT, COLOR and MIX macros.
- EQ metering with 4× polyphase-oversampled true peak to ITU-R BS.1770 (±0.05 dB), with LUFS targets for nine streaming platforms.
- Native CLAP support alongside VST3 — with Outboard-EQ also supporting multichannel up to Dolby Atmos 9.1.6 and a per-band channel mask.
How we work
Our plugins are one-time purchases with perpetual licenses — no subscription, no rental. The website sets no tracking or marketing cookies, and the plugins collect no usage analytics; the only data they send is what's needed to activate your license. Support comes straight from the person who wrote the DSP, and every release is documented in the changelog.
