About

Velvet Machine

This audio effect plugin generates unique sonic textures by blurring and stretching sounds. It can create reverb-like qualities, act as a delay, and offers extensive control over its volume envelope and timing. Requires a compatible host app and a relatively modern device for optimal performance.

Highlights
  • Real-time convolution with enveloped velvet noise
  • Sound stretching and blurring up to 10 seconds
  • Reverb-like textures with flexible volume envelope
  • Variable density random multi-tap delay
  • Host tempo sync for time and predelay
  • High cut and low cut filters
  • Adjustable dry/wet mix

Sonic texture generator / blur / non-linear reverb *** WARNING *** Velvet Machine is an Audio Unit v3 plugin and requires a compatible host such as GarageBand, AUM, Cubasis, Audiobus etc. The provided standalone app does NOT support the currently deprecated Inter-App Audio. *** Velvet Machine is a CPU-intensive effect at high settings. A *minimum* of 5th Gen iPad, iPhone 6s or 1st Gen iPhone SE is required to run a single instance at maximum settings. However, shorter times and/or lower densities use much less CPU. *** Velvet Machine is a unique audio effect based on real-time convolution with enveloped velvet noise. It's designed to: - Stretch and blur out even short sounds to lengths of up to 10 seconds - Produce reverb-like textures with flexible volume envelope (including reverse, fading in and out, pulsating etc.) - Work as a variable density random multi-tap delay (bordering on granular-like sounds) PDF manual and video demos are available on developer website. Features: - Flexible volume envelope with arbitrary number of segments and curvature - Effect time ranging from 50 ms to 10 s - Response density adjustable from 1 to 2000 repeats per second - Predelay up to 1 s - Host tempo sync for time and predelay parameters - High cut and low cut filters for the effected signal - Mix adjustable from 100% dry to 100% wet - Mix Lock to switch presets while keeping the dry/wet mix constant

BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.
