New Decimator Bitcrusher In 1U

Mosaic has introduced Decimator, a 1U DSP bitcrusher, with independent bit-depth and sample-rate reduction.

Here’s what they have to say about it:

“Bit reduce and downsample audio into oblivion with Decimator. Lo-Fi sweet spots are just a knob turn away with independent control over each decimation aspect, and a dedicated dry/wet mix knob to bring the heat when you want it. Effortlessly turn your karplus-strong plucks into heavy metal power chords, or harmonically complex samples into 8-bit chiptune goodness within a single module. Sonic destruction is a patch away with Decimator!”


  • High Fidelity 96kHz, 24-bit audio engine
  • Multifaceted decimation DSP effect
  • Downsampling
  • Bit depth reduction
  • Mix between dry and wet signals

Note: Mosaic panels conform to the Intellijel 1U format, but Pulp Logic style panels are also available.

Pricing and Availability:

Decimator is available now for $119 USD.

  1. The module is nice, but the description is incorrect. It makes no sense to reduce the bit depth if the input signal is analog (so it doesn’t have bit depth, because it is not quantized). Also, it makes no sense to talk about downsampling of a signal that is not sampled at all. These two operations are well defined if the original signal is already digital. For analog signal it is just sampling and quantization.

    1. Are you new to this?
      It’s a digital module.
      you can do analog down sampling with sample and hold …
      Both ways make a lot of sense sonically.
      Modulate it with key follow and let your jaw drop.

      1. I’m not new to this, you just didn’t understand my comment. A digital signal (already sampled) can be DOWNsampled (i.e. resampled with a lower frequency). This module may be digital inside, but its input signal is ANALOG. So the input signal here is not DOWNsampled, it is just SAMPLED (first time). The same applies to bit crushing: you can reduce bit depth if the signal is already digital. But here, the input signal is analog, so it doesn’t have bit depth that could be reduced.

        I have nothing against this module, it is pretty nice. I’m just pointing out the wrong terminology used.

        1. The description of it having a “High Fidelity 96kHz, 24-bit audio engine” sure makes it seem like it is first converting the analog input to a high resolution digital signal, and then internally downsampling/bit reducing that. The manual doesn’t expressly say, but I’d assume the “dry” signal from using the wet/dry knob at fully dry has been converted from analog to digital to back to analog (to avoid any phasing caused by the latency any digital processing introduces when mixed back with the wet signal).
