soundfruuze vs Matrix Vocoder
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
Matrix Vocoder
Transform your voice into an electronic instrument with this app, simulating classic analog vocoder sounds. It analyzes input signals, performs spectral analysis, and reassembles synthetic speech using filter banks and replacement signals.
- 32 channel filterbank with analog filters
- Stereophonic synthesis with alias-free oscillators
- External carrier input
- Voiced/Unvoiced detection and pitch tracking
- Formant shift
- Patchbay for channel connection
- 16 internal oscillators for choir sounds

Matrix Vocoder transforms your voice into an electronic instrument! The Vocoder was invented by Homer Dudley in the mid-30's of the last century. Dudley worked at Bell Laboratories, and this is where the first Vocoder took shape. The Matrix Vocoder is designed to properly simulate the classic analog Vocoder sound made famous e.g. by the music of the german band Kraftwerk. At there last world tour they used in fact the PC version of our Matrix Vocoder on stage ! The epic Cylon Robot voice is The basic function of a Vocoder is characterised by an analysis of the input signal, usually speech but other type of inputs can also be very interesting. In a special filter bank, a spectral analysis is performed and signals are developed which follows the amount of spectral energy in each channel. Another part of the analyser tests if there are unvoiced or voiced sounds at any particular time and extracts the pitch of the voiced sounds. The output section of the vocoder consists of a stereophonic synthesis filter bank which assembles the new synthetic speech from the characteristic filter envelopes from the analysis stage together with an external or internal replacement signal. - 32 channel Filterbank with 8-pole Butterworth analog filters - Stereophonic synthesis with analog modelled alias free oscillators. - External carrier possible ( left channel = voice / right channel = carrier ) - Voiced/Unvoiced detection - Pitch tracking - Formant shift - Matrix uses patchbay to connect analysis and synthesis channels. - Pan position and level for each channel. - 16 internal oscillators with unlimited voices for choir like sounds. - Stereo wide panorama parameter for internal generator. - Optional monophonic generator with Glide setting. - Internal noise generator. - Effect AudioUnit and Music Effect AudioUnit - stand alone / Audiobus 3 / IAA

Verdict
The clearest difference is review sentiment: soundfruuze at 79% against Matrix Vocoder's 42%. soundfruuze also leads on rating (4.8 vs 4.3) and update cadence (fortnightly vs every 15 months). Matrix Vocoder's advantage is chart position (#181 vs unranked) and device support (3 vs 1). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
