Tools that sound
like something
actually
happened.

Character audio plugins for sound that needs a little wear.

Built slowly somewhere in Northern Italy. Released when ready.

Plugins

Not the cleanest. Not the most obedient. Not designed to disappear in the mix.

The Tascam Porta Two
was not a precision
instrument.

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.

Sections
Preamp

Input gain with selectable character. CLEAN is transparent and linear. HOT is a double-stage tanh saturation modeled on the LM833 op-amp — the harder you push the input, the more it breaks up. Two EQ shelves at 150 Hz and 10 kHz, ±15 dB each.

Tape

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.

Output

Logarithmic output fader, –60 to +12 dB. Ghost adds azimuth misalignment in the first half of its range, then fades in print-through echo — the sound of a tape that remembered the previous session. Auto Gain compensates for level changes introduced by the preamp and tape stages.

Suggested settings
Subtle Analog
CLEAN · INPUT noon
DRIVE 20% · GHOST off

Warmth and gentle saturation. The kind you notice when it's not there.

Classic Lo-Fi
HOT · INPUT 70% · DRIVE 50%
FLUTTER 30% · AGE 40% · 1⅞ips

The sound of a tape that has been used.

Ghost Tape
CLEAN · DRIVE 30% · GHOST 60%
AGE 20% · DBX on

Azimuth smear and faint echo of the previous session bleeding through.

Full Destruction
HOT · everything maxed
SPEED 1⅞ips · GHOST full

Not for the faint of heart.

About

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.
