Features & Capabilities

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 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

I can’t seem to find anything I’m doing wrong but seems pretty busted to me

Works for me (iOS 17.6) and works with AudioBus3 as the site stated it would.

I have no idea how to apply this app! If I could get a refund I would. That being said, I gave it a four star rating because it seems very cool and I am probably just ignorant of the application! Too much work goes into developing an app to have it devalued by me, but it needs instructions!
