This app transforms image data into sound, allowing for unique musical compositions and experimental sound design. It offers control over pitch, timbre, and envelopes to create shape-timbre relationships from visual input.
- Image sonification
- Visual music composition
- Experimental sound design
- Pixel luminance audification
- Shape-timbre relationships
- Adjustable pitch and timbre
- ADSR envelope control

VOSIS is a synthesizer combining audification of greyscale pixel data with several image filters. It is a tool for image sonification, visual music composition, and experimental sound design. The audification of pixel luminance values creates shape-timbre relationships. Pixel scan rate is controlled in terms of note interval, octave, and scale to give varying pitch between image regions. The ADSR envelope allows one to play images as a non-linear sequence of pitches with varying wavetable/timbre. For more features including presets and unlimited recording see VOSIS Pro.

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.
- 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.

Verdict
VOSIS and Land Waves both sit at 4.2 stars, but that hides the real split: 86% of VOSIS's written reviews are positive against 50% of Land Waves's. VOSIS also leads on update cadence (every 8 months vs every 31 months). Land Waves's advantage is iOS requirement (8.0 vs 13.0). On price, rating, ratings volume and ads there is nothing between them.
