VoMPE (Voice over MIDI Polyphonic Expression) analyzes voice input and then outputs polyphonic MIDI notes based on formant frequencies representing voice characteristics. The process of voice production can be modeled by the vibration of the vocal cords and the resonance of the vocal tract. In this case, the voice spectrum is…
SpakerObjects, a customized version of SoundObject, specializes in binaural reproduction of stereo speaker-based sound fields. Headphone monitoring of stereo sound that is assumed to be play-backed from speakers degrades sound localization. Similarly, stereo speaker sound mixed by headphone monitoring leads to sound imbalance. In this case, it is necessary to…
PolyPortamento by suzumushi is a Virtual Instrument Audio Plugin for Windows. It functions as a VST 3 Plugin. PolyPortamento is a plug-in enabling polyphonic portamento with MPE synthesizers. MIDI Polyphonic Expression (MPE) specification is applicable to polyphonic, that is, MIDI channel-based pitch bend, as well as portamento and legato functions. However, in a…
AudioQAM simultaneously modulates phase and amplitude of audio input, and as a result, creates unexpected sound. Quadrature Amplitude Modulation (QAM) is widely used in digital communications. AudioQAM is derived from digital quadrature amplitude modulators and refined for audio processing. AudioQAM supports sine as well as triangle, square, and sawtooth waveforms for carrier…

SoundObject creates a binaural sound with the senses of three-dimensional sound localization from a monaural acoustic source and its positional information. Conventional three-dimensional binaural sound processors implement sound localization with the convolution of an acoustic source and head-related impulse response (HRIR) that represents scattering by the head. Since the convolution…
