gravel
Key Features
- Three distortion modes in one plugin: hard-clipping drive, smooth non-integer bit depth reduction (1 to 24-bit), and sample rate reduction
- Built-in envelope follower with adjustable attack and release (1 to 5000 ms) for amplitude-driven dynamic modulation of all effects
- Positive and negative modulation routing lets the envelope follower increase or decrease distortion intensity based on input dynamics
- Additional mod knob provides extra modulation control over the audio input for fine-tuned sound shaping
- Excels at transient-aware drum processing, adding sustain and grit to percussion without smashing the attack
- Ideal for lo-fi sound design, retro digital degradation, and creative audio mangling with dynamic character
Description
Gravel by Taiga DSP is a multi-mode distortion plugin that combines drive, bitcrushing, and sample rate reduction into a single streamlined interface. What sets it apart from typical bitcrushers is its built-in envelope follower, which uses the input signal's amplitude as a modulation source to make all three distortion types respond dynamically to incoming audio.
The drive section delivers hard-clipping distortion for adding grit and sustain, while the bit depth control offers smooth, non-integer reduction from 24-bit all the way down to 1-bit for everything from subtle warmth to extreme digital destruction. Sample rate reduction rounds out the distortion trio, introducing aliasing artifacts and retro lo-fi character.
The envelope follower is the real creative engine here, with adjustable attack and release times from 1 to 5000 milliseconds. It can modulate any of the three distortion parameters positively or negatively, allowing transient-sensitive processing that responds to the dynamics of your audio in real time.
Gravel particularly excels at beefing up drums and percussion without destroying transients, thanks to the envelope follower's ability to shape distortion around the attack phase. It also shines for lo-fi sound design, retro game-style audio degradation, and adding modulated crankiness to synths and vocals.
Available as a VST plugin in both 32-bit and 64-bit versions for Windows only, Gravel is a lightweight 1.9 MB download. Note that the developer site (taigadsp.com) is no longer active, though the plugin remains available through SoundShockAudio.

Frequently Asked Questions
What makes Gravel different from a standard bitcrusher?
Gravel goes beyond simple bit reduction by combining three distortion types (drive, bitcrushing, and sample rate reduction) with a built-in envelope follower. The envelope follower uses the audio signal's amplitude to dynamically modulate the distortion parameters, so the effect responds to how hard you play rather than applying a static effect.
Can Gravel process drums without ruining the transients?
Yes, this is one of Gravel's standout strengths. By adjusting the envelope follower's attack and release settings, you can shape the distortion to preserve transients while adding sustain and grit to the body of percussive sounds. Users frequently praise it for beefing up drums without making them sound flat or overprocessed.
Does Gravel work on macOS or as an AU/VST3 plugin?
No, Gravel is available only as a VST plugin (32-bit and 64-bit) for Windows. There is no macOS, AU, VST3, or AAX version. The developer (Taiga DSP) has since gone inactive, so additional format support is unlikely.
Is the Taiga DSP website still active?
No, the Taiga DSP website (taigadsp.com) is no longer online as of 2021. However, the plugin itself remains fully functional and is still available for download through SoundShockAudio and other plugin archives.
