voc-one is a vocal synthesis plugin that combines a simple analog-style synthesizer with a morphable formant filter bank to recreate realistic vocal sounds. It simulates the glottal pulse to capture the essence of vocal tone, while the formant filter shapes the sound with warmth and clarity. This approach provides a flexible way to generate natural-sounding vocals with a wide range of character.

The formant filter offers control over 11 distinct vowel spectra recognized in phonetics, allowing smooth and subtle morphing between vowel sounds. Users can adjust the register and emphasis of the filter to explore various vocal timbres, from soft and airy to strong and focused. With 8 built-in presets and room for 8 additional ones, the plugin encourages creative exploration and customization for unique vocal textures.

voc-one also includes a high-quality built-in reverb effect based on UDReverb, enhancing the spatial depth of the synthesized vocals. While the plugin demands considerable CPU resources, it is optimized for smooth performance on systems with at least a 1.2GHz processor. This makes voc-one a powerful tool for producers seeking expressive and adaptable vocal synthesis in their music production workflow.
