soundfruuze vs Hearing Space
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
soundfruuze
This app records and manipulates the last 10 seconds of live audio. It offers five lanes, each with unique sound manipulation effects like granular synthesis, looping, and FFT processing. Customize sound by touching lanes, controlling parameters like speed, pitch, and effects.
- Live audio recording and manipulation
- Five customizable effect lanes
- Granular synthesis and scrubbing
- FFT-based freezing and looping
- Frequency shifter, ring modulation, reverb
- Looper with adjustable speed and pitch

'soundfruuze' is an exprerimental live sampler / looper / granular and FFT scrub effect It records live the recent 10 seconds of audio and allows you to manipulate it with special controls. The interface is divided into five “lanes”, sound is produced by touching the lanes. Each lane can be set up to use different effect and has various control parameters mapped to the touch position: Scratch Most basic lane type. You can control the volume of the resulting sound and smoothness of the position interpolation. Lesser smooth value produces the sound with more high frequencies. Speed Another basic playback type. Starts playing from the position in the sound that you selected with touch. Vertical position controls playback speed, horizontal parameter is assignable. Granular Freeze Allows you to select the sound at some position and use both horizontal and vertical coordinates of touch as 2 independent parameters. You can control volume, playback speed (pitch) and the grain size. Granular Scrub This type of lane is very similar to granular freeze but it allows to change the position of the grain after its start. Granular Stream This lane type enables granular playback with random parameters. You can randomise grain position in the selected range, speed, grain size and pan. There is special control for that type lane. The 2-dimensional slider is assignable so you can change 2 parameters for each touch independently. FFT Freeze and FFT Scrub In both FFT types of lanes another algorithm is used to process sound. In both FFT Freeze and Scrub sound is analyzed with the FFT transform and divided into frames. FFT Freeze allows you to select the frame at the desired sample position and to play it making the sound “freeze” at this point. Looper This lane type allows you to make loops / repeat large grains of sound. When you touch a looper lane, a new looper control is created and is kept there until you turn it off with the red ‘close’ button. You can change loop speed, volume, size and position for each loop individually or for all loops on one lane together using additional controls FFT Looper This type works the same way as basic Looper but allows to change playback speed while keeping the pitch. It uses FFT algorithm for playback allowing constant pitch for any playback speed and the same FFT effects (gate and phase randomisation) Each lane has also five effects: - Frequency shifter - Ring modulation - Sample-and-hold (" lo-fi") - HP/LP filter - Reverb
Hearing Space
This experimental art application uses AI and machine vision to analyze images, inferring spatial depth and structure. It then transforms these spatial relationships into interactive soundscapes, allowing users to explore a non-human model of space through touch. The app treats your device as a perceptual instrument to reveal AI's internal logic.
- AI-based image analysis
- Machine vision for spatial inference
- Interactive sound generation
- Touch-based sonic exploration
- Perceptual instrument interface
- Artistic and exploratory experience

Hearing Space-Time is an experimental art application that explores how artificial intelligence perceives space and transforms it into sound. Using machine vision, the app analyzes images to infer spatial depth and structure. These inferred spatial relationships are translated into sound, allowing users to interact with and listen to a non-human model of space. By touching different areas of an image, users activate sonic responses shaped by the machine’s interpretation rather than by visual representation alone. The app treats the mobile device as a perceptual instrument rather than a passive screen. Sound becomes a medium through which machine vision’s internal logic is revealed, inviting reflection on the relationship between human perception, algorithmic interpretation, and spatial understanding. Hearing Space-Time is designed as an artistic and exploratory experience. It does not aim to simulate reality, but to expose how artificial intelligence reconstructs and reorganizes the world through inference.

Verdict
The clearest difference is price: Hearing Space at Free against soundfruuze's $6.99. Hearing Space also leads on update cadence (every 4 days vs fortnightly) and device support (3 vs 1). soundfruuze's advantage is ratings volume (12 vs 3). On rating, ads, in-app purchases and iOS requirement there is nothing between them.
