BLEASS Vox is your gateway to effortless sonic manipulation. This cutting-edge processor immerses you in a world of sonic possibilities, effortlessly shaping every nuance of your vocal performances. Formant processing lets you alter the perceived character of a voice independently from its melody, opening up everything from natural tonal variations to dramatic vocal transformations. The Unison processor can spread up to 10 detuned voices across the stereo field, adding width, depth and weight without requiring a complex vocal processing chain. Vibrato adds controlled pitch movement for anything from gentle modulation to more pronounced special effects, with immediate hands-on control. BLEASS Vox includes two processing modes for different workflows. Real-time mode prioritizes speed and responsiveness for recording and live performance, while Standard mode delivers the accuracy needed for editing and mixing. BLEASS Vox can be used as an AUv3 plugin or standalone app on iPhone and iPad. BLEASS Vox is also available for Windows, macOS and Linux.
