Multiplex Vocoder 3 is a powerful 64-bit standalone software designed for sound design and music production. It enables the use of any VST or AU instrument as a vocoder carrier, offering expansive creative possibilities. With the ability to run four vocoder layers simultaneously, users can craft unique vocal effects and complex sound textures by processing voices or audio files.

This vocoder supports multiple input options including microphones and audio players, and can process various audio formats such as WAV, AIFF, and MP3. It features an audio sample editor for selecting specific segments to process, along with playback controls like speed adjustment, reverse playback, looping, and pitch shifting. The software also includes a master rack with three VST/AU plugins, allowing detailed control over pitch and frequency shifting, dry-wet mixing, and cross-morphing between different vocoder outputs.

Additional features include input-dependent activation of vocoder outputs, autokey functionality for playing without a MIDI keyboard, and extensive recording capabilities supporting up to 192kHz/32-bit quality. Users can record source input, individual vocoder layers, and mixed outputs in WAV or AIFF formats. Multiplex Vocoder 3 is compatible with both Windows and Mac systems, requiring 64-bit architecture and recommending at least 4GB of RAM for optimal performance.
