Boutique Audio Plugins — VST3 / AU
Character audio plugins for sound that needs a little wear.
Built slowly somewhere in Northern Italy. Released when ready.
Not the cleanest. Not the most obedient. Not designed to disappear in the mix.
Cassette channel strip. From clean analog warmth to full tape destruction.
Released in 1985, it was a four-track cassette recorder built for bedrooms, not studios. Its preamp clipped early and unapologetically. Its transport wobbled. Its tape hissed. People made records on it anyway — and those records sound like nothing else.
PortaTwin models the full signal chain: the way the preamp colors and saturates at different input levels, the pitch drift of an aging transport, the bandwidth loss and hiss of worn tape. It works as a subtle analog glue or as a deliberate lo-fi tool. Everything in between is fair game.
Input → HPF 10Hz → PREAMP GAIN (CLEAN / HOT) →
[HOT] IC1A TANH → EQ LOW 100Hz / EQ HIGH 6.5kHz → LP ~12kHz → IC2A TANH →
[CLEAN] EQ LOW 100Hz / EQ HIGH 6.5kHz → SOFT CLIP →
[TAPE] TAPE SAT (B-H curve) → HEAD BUMP ~200Hz → WOW/FLUTTER → HISS → DBX →
VU → OUTPUT LEVEL (log) → GHOST azimuth 65→90% → DC BLOCKER
Input gain with selectable character. CLEAN is transparent with a soft clip ceiling. HOT runs two tanh stages modeled on the LM833 op-amp, with the EQ shelves placed between them — so the tone shaping happens inside the saturation, not after. Shelves tuned at 100 Hz and 6.5 kHz, ±10 dB. Switching between modes is completely inaudible — a 10 ms crossfade prevents any click.
B-H curve saturation with bias interaction and head bump around 200 Hz. Multi-LFO pitch modulation — wow at 0.85 Hz, flutter at 4.8, 6.3, and 8.1 Hz. Wear controls hiss level and progressive high-frequency loss. DBX reduces noise aggressively when signal drops. Speed changes everything.
Logarithmic output fader, –60 to +12 dB. Ghost applies a progressive stereo azimuth split — starting at 65/35 and widening to 90/10 as you push it — then fades in print-through echo at the top of its range. The sound of a tape that remembered the previous session. Auto Gain compensates for level changes from preamp and tape.
Warmth and gentle saturation. The kind you notice when it's not there.
The sound of a tape that has been used.
Azimuth smear and faint echo of the previous session bleeding through.
Not for the faint of heart.
Free to download. Pay what you want if you use it.
macOS — Apple Silicon and Intel. VST3 + AU.
The installer is currently unsigned. macOS will ask you to allow it manually once — instructions are in the package.
Pointless Audio makes tools with a point of view. Not the most accurate emulation, not the most feature-complete plugin — just software that pushes audio somewhere interesting and stays out of the way while doing it.
The name is not a joke. Pointless means without a point to prove. It also means exactly what it sounds like, depending on the day.
