PCM2612 Retro Decimator Unit FREE Bitcrusher Plugin

Inphonik has announced the release of PCM2612 Retro Decimator Unit, a free bitcrusher effect plugin modeled after the Sega Genesis Model 1 amp output circuitry.

PCM2612 is based on the decimation effect obtained with the Yamaha YM2612, best known for being the Sega Genesis/Megadrive video game console’s sound chip.

It gives a distinctive 8-bit quantized and aliased effect to any sound you plug into it. On one hand, it adds distortion due to the 8-bit quantization, and on the other hand, it adds aliasing due to the resampling.

Also, the PCM2612 can emulate the line-out circuitry of the Sega Genesis Model 1, released in 1988.

PCM2612 comes with two graphical user interfaces: box, suited for vertical displays, and rack, which is logically at ease with widescreens.

Here’s what Inphonik told us about the new plugin:

The PCM2612 Retro Decimator Unit is the continuation of our work made on the RYM2612 Iconic FM Synthesizer, expanding its ecosystem. As much as the RYMCast Genesis VGM Player, the PCM2612 has a place of choice as a companion effect plug-in that completes our offer in our YM2612 product line.

We’re proud of this little effect plugin since it resolves a problem we had with the RYM2612’s PCM playback feature that not all DAW could use appropriately, due to its audio-in functionality that’s not so common for an instrument plugin.

The PCM2612 is as simple as possible: one FX, one knob. Yet, so much character! It’s our tribute to the magnificence of the 8-bit sound. This decimated noise has shaped our youth. It was the mark of the prowess of the engineers and the artists who produced the classic video games and original soundtracks we still love today.
