Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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

Crusher is an easy-to-use Filter and Bit Crusher effect available as an AUv3 plugin and standalone. This plugin is inspired by the effect section of our instrument plugin Noises. Crusher features a multimode filter (lowpass, highpass, bandpass, notch) with 2 or 4-pole and an output gain, along with a crisp bit crusher (bits, downsample, mix) paired with a harshness control taken from our plugin Reels.
