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 call

The clearest difference is update cadence: Voice Synth at every 6 weeks against Matrix Vocoder's every 15 months. Voice Synth also leads on review sentiment (62% vs 42%) and ratings volume (333 vs 20). Matrix Vocoder's advantage is rating (4.3 vs 4.1) and price ($5.99 vs $8.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Matrix Vocoder holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: Voice Synth has 333 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 62% of Voice Synth's written reviews are positive against 42% of Matrix Vocoder's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Voice Synth ships an update every 6 weeks, Matrix Vocoder every 15 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
