instrument + effect

PS1 synth plugin.

simpleSPU is a sampler instrument and an audio effect modelled on the PlayStation's sound chip. It plays samples back the way the console did, with 4-bit ADPCM, Gaussian interpolation and the chip's own reverb, for the sound of late-90s game soundtracks.

Includes 14-day free trial (all features enabled, no card needed) · VST3 & AU · macOS, Windows & Linux

What it looks like.

These are screenshots of the plugin itself. The mascot is drawn live from a 3D model and reacts to what you play. There's a light theme and a dark theme.

two plugins

An instrument and an effect.

The instrument

A sampler with around 100 presets: pads, strings, choirs, bells, keys, leads, basses, drum kits and atmospheres. Play it from any MIDI track.

  • 24 voices by default, up to 64
  • 4-bit ADPCM samples and the console's envelope shapes
  • Attack, release and detune on the main page
  • Also runs as a standalone app on Linux

The effect

Runs drums, vocals, guitars or a full mix through the same engine. Its presets go from subtle, like Console Room and Warm Grit, to heavy, like 2-bit Destroyer.

  • Input gain, output gain and a dry/wet mix
  • All nine reverb types from the instrument
  • Covered by the same licence as the instrument

how it works

Modelled on the original sound chip.

4-bit ADPCM

Samples are stored in the console's own compressed format, which gives them a slightly noisy character.

Gaussian interpolation

Notes are pitched with the chip's four-point Gaussian interpolation, which rounds off the high end.

The chip's reverb

Nine reverb types, from Room and Hall to Space Echo, built from the chip's published settings and run at half the sample rate, as on the hardware.

Consistent at any sample rate

The engine runs at 44.1 kHz internally, so presets sound the same in 44.1, 48 and 96 kHz projects. Every control can be automated.

Optional extra grit

The Crush knob lowers the bit depth and sample rate further if you want a rougher sound. Each preset is set up at 50%.

No ripped game audio

Every sample is either made by us or comes from openly licensed recordings.

faq

Common questions.

Does it work on Mac?

Yes. simpleSPU runs on Mac, Windows and Linux. VST3 on each, plus AU on Mac.

How does the free trial work?

It lasts 14 days from the first time you open either plugin, with everything switched on. When it ends, the instrument goes quiet and the effect passes audio through unchanged, so your projects still open. Enter a licence key and it carries on.

Does one licence cover both plugins?

Yes. One licence covers simpleSPU and simpleSPU FX, and they share one trial too. It's £19.99 at launch, then £29.99.

Is this an official Sony or PlayStation product?

No. simpleSPU is an original PS1-style instrument and effect, inspired by PlayStation-era console music. It is not affiliated with Sony or PlayStation.

Does it use ripped game samples?

No. Every sample is either synthesised by us or made from openly licensed recordings. The console character comes from modelling how the sound chip stored and played samples: 4-bit ADPCM, low sample rates, Gaussian interpolation and a half-rate reverb.

Which DAWs does it work in?

Hosts that load VST3 plugins, or AU on macOS, such as Logic Pro, Ableton Live, FL Studio, REAPER and Bitwig Studio.

Is simpleSPU a SoundFont player?

No. simpleSPU is its own synth and effect plugin. The SoundFont player is simpleSF2, a separate simpleSoundbank product.

Who's the girl in the headphones?

She's simpleSPU's mascot. She appears in the plugin too, and reacts to what you play.

How do I make PS1-style music?

Low sample rates, a soft top end, one big reverb and no more than 24 notes at once. Our guide How to make PS1-style music in your DAW covers it step by step, with or without simpleSPU.
