Hermetic Modular Capicola Brings Real-Time Time Stretching To Eurorack
Hermetic Modular’s Capicola is a 12HP Eurorack module that uses a keyframe-based approach to stretch, pitch-shift, slice and distort stereo audio in real time.
Its core technology, called Extrema Sampling, converts 48kHz audio into a non-uniform stream of keyframes representing local peaks and valleys.
The keyframe representation is then used for time stretching, slicing and nonlinear processing. Pitch and time can be controlled independently, while envelope followers, external CV and triggers can be used to modulate the processor and create self-modulating patches.
Features:
- Real-time stereo time stretching
- Pitch and time independently controlled
- Extrema Sampling keyframe engine
- Non-uniform keyframe representation of audio
- Grain Size control for time-stretch processing
- Quality control for variable keyframe density
- Real-time pitch shifting over ±12 semitones
- Threshold-based transient detection and slicing
- True-freeze behavior through the Stretch control
- Keyframe-domain nonlinear distortion
- Feedback loop with saturation and filtering
- Two independent envelope followers
- Two trigger outputs for detected transients
- External ±5V CV modulation
- Dedicated modulation routing and attenuverters
- Parameter lock for every knob
- 16 preset slots
- 48kHz/24-bit stereo audio
- 12HP, skiff-friendly Eurorack format
Hermetic Modular Capicola is available now for $389 USD. It’s also available as an open source project.
