Vintage DA Sound
The coloration and warmth characteristic of circuits from classic samplers recreated with painstaking accuracy
Far More than Just a Bit-Crusher
Approximative anti-alias filter and image filter, adjustable jitter and dithering, and two alternative quantization algorithms for total control over the process.

Multimode Filter

Works in pre or post, along with a resampler module to allow further sculpting of the signal.
Under the hood
Decimort Recreates the Colouration and Adds the Vintage Sampler's Magic to Any Sound
Electronic music (especially Hip-Hop) producers have long been aware that classic samplers (such as early Akai and E-MU units) had a character and sound all their own: they added a "grit" and "color" to the samples and loops they played back which made them sound "fat" and sit well in a mix. This sound coloration was due to the encoding techniques, lower sample rate and bit depth, and conversion circuits used by these early samplers.
Decimort recreates this coloration and adds that vintage sampler magic back to any loop, any bassline, or any sound played through it for that matter! Beyond vintage sampler emulation, it’s also the perfect bit-crusher with filter, capable of extreme settings for dramatic results.

Approximation filter
A very steep low-pass pre filter (Approximative Filter) coupled with the resampling frequency that removes all harmonic content above it, ensuring no aliasing will appear below this frequency in the spectrum.
Two quantization methods
Two available quantization methods; the mid-raiser and mid-tread decimation algorithms, each of them characterized by a drastically different dynamics response.
Two in One
Decimort is also equipped with analog-like filters with adjustable resonance that allow further sculpting of the signal. These can be used to smooth the sound or remove sonic artefacts introduced into the signal path by the modeling process to your taste.
Adjustable Jitter
An unprecedented feature in the bit crusher’s world which introduces short-period, random fluctuations to the resampling frequency, thus making the process even more sonically interesting by producing a type of harmonic distortion you’ve likely never heard in this context
Controllable dithering
Dithering was conceptually developed as means to reduce audible quantization errors by masking the harmonic distortions they cause. We added controllable dithering to increase number of ways in which you can (mal)treat the sound.
Images filter
Post-resampling filter (Images filter) is synchronized with the resampler, gives control over amount of aliasing images appearing above resampling frequency when enabled.
The Highest Quality Low-Quality Effect
While this tagline may seem like an oxymoron on the surface, allow us to explain: The advanced signal processing algorithms within Decimort simulate the complex behavior of the entire (re-)sampling path that exists in every AD/DA converter, and with version 2 comes far greater control over the process!
Decimort has zero internal aliasing—in fact, the only aliasing present is the emulated aliasing of the classic samplers we modeled when creating it. Unwelcome artefacts are completely absent in the processed signal: only the desirable, modeled ones remain.
