About

Land Waves

This app generates sound waves from a 1D reaction-diffusion system simulation. It translates pixel brightness into audio frequencies, creating complex soundscapes from simple mathematical models found in nature.

Highlights
  • 1D reaction-diffusion system simulation
  • Sonification of pixel brightness
  • Generates complex soundscapes
  • Mathematical models of natural fluid behaviors
  • Translates pixel values to audio frequencies

Raw sonification of a 1D reaction diffusion system. Reaction diffusion systems are mathematical representations of the behaviours of fluids that can be found in nature. A key characteristic of these systems is that the initial parameters are simple but the resulting process can be extremely complex. Here, each pixel brightness affects the brightness in the corresponding pixel line. Frequencies of the sound waves are the sonification of these pixel values.

About

BLEASS Slow Machine

Thanks to 3 different yet complementary ways of manipulating time with creativity, BLEASS Slow Machine can deepen any beat by completely or partially slowing down the audio signal, transform epic leads into heavy basses, and add some “tape stop” effect with precision either by touching the X/Y Stop trigger, or by dialing in precise sequence automations. TECHNICAL DESCRIPTION: BLEASS Slow Machine offers both sequenced and live ways to manipulate time thanks to 3 stages: ____ SLOW DOWN stage: Creative and straightforward slow down effect that modulates both rhythm and pitch. - Loop Size: Slow Down resets its reading position according to the Loop Size. A Loop Size of ‘1 bar’ means that the reading position is resynced with the host reading position every 1 bar. - Speed: controls the speed of the played loop relative to the default speed. (For example ‘½’ means that audio is played back at half its original speed, which means one octave lower). - Quantization: When this option is ON, every change in Loop Size and in Speed will wait until the end of the current loop to be effective. When it is set to OFF, the change is immediate. - Filter: keep a selected frequency band of the slowed signal. When the filter is ON, the middle colored band is processed by the effect while the low and high bands remain unchanged. - Fade: Sets the duration of the crossfade between loops. - State: Activates or deactivates the SLOW DOWN stage - Dry/Wet: mixes the dry and wet signals ____ TIME STOP stage: Especially made for performance, TIME STOP gives an intuitive and visual way to instantly create a classic tape stop effect. - Trigger: the “Stop” button triggers the time stop effect within a given duration (set by the position of your finger along the Y-axis) and following a curve (set by the position of your finger along the X-axis). - Mode: choose between 4 time stop modes: ‘Step’, ‘Ramp Up & Down, ‘Ramp Down’ and ‘Ramp Up’. _ In ‘Step’ mode, the speed instantly goes to 0 when the trigger is hit and goes back to 1 when the trigger is released. _ In ‘Ramp Up & Down’ mode the speed is ramped down to 0 when the trigger is hit and ramped up to 1 when it is released. The duration and curve of the ramp is set by the position of your finger on the control. _ In ‘Ramp Down’ mode, the speed is ramped down to 0 when the trigger is hit and instantly goes back to 1 when released. _ In ‘Ramp Up’ mode the speed instantly goes to 0 when the trigger is hit and is ramped up to 1 when released. - Hold: when Hold is ON, the trigger is not released until Hold is turned OFF. - Speed: precise control of the play speed. - State: Activates or deactivates the TIME STOP stage - Dry/Wet: mixes the dry and wet audio signals ____ SPEED SEQUENCER stage: The speed sequencer stage offers a unique way to program speed variations in your music. - Length: sets the number of steps in the sequencer. - Resolution: sets the duration of a sequencer step. - Grid Snap: when ON, steps snap to the grid allowing a precise rhythmic and harmonic editing. - Sequencer: sets a playing speed per step. Each step has 4 different curve modes: ‘Step’, ‘Link’, ‘Ramp Up’ and ‘Ramp Down’. Change the curve mode by tapping the curve icon at the bottom of each step. - Amount: controls the amount of sequencer speed modulation. 100% means that speed can go from 1 to 0 (50% means that speed can go from 1 to 0.5). - Randomness: sets the amount of randomness of the sequencer. If randomness is 50%, a step value will be a random value between stepValue +/- 0.5 - Fade: controls the crossfade duration between each step. - State: Activates or deactivates the Speed Sequencer stage - Dry/Wet: mixes the proportion of dry and wet signals Check out www.bleass.com for video tutorials and more info! * PLEASE NOTE: this is an Audio Unit Effect plugin (AUv3) which requires a compatible host such as AUM, GarageBand, Cubasis, BM3 or Auria. Standalone mode also available for demo purposes.
