Velvet Machine Brings ‘Convolution Fairy Dust’ To Your iPad

Developer Yuri Turov shared this preview of Velvet Machine, a new audio effect that promises to bring that ‘velvet noise convolution fairy dust’ to your audio.

Velvet Machine is an 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)


  • Flexible volume envelope with arbitrary number of segments and curvature
  • Effect time ranging from 100 ms to 10 s
  • Response density adjustable from 1 to 2000 repeats per second
  • Predelay up to 500 ms
  • High cut and low cut filters for the effected signal
  • Mix adjustable from 100% dry to 100% wet with no dry signal
  • Mix Lock to switch presets while keeping the dry/wet mix constant

Pricing and Availability

Velvet Machine is available now for $5.99 USD.

    1. Convolution is typically used in reverb applications to simulate the dynamics of various types of spaces like rooms and halls and so forth

      In this app it seems they have decoupled the convolution mechanics into a standalone synthesis effect, which probably acts a bit like granular methods on a much different scale
