Tune your everyday microphone to suit your voice. Voice Booster adjusts microphone levels and speech clarity, then sends the processed audio to your calling or streaming app through a virtual audio cable. This is the English edition. The interface, connection guide and PDF manuals are in English. Japanese edition: https://cat-tool.booth.pm/items/8717965 ■ Main features • Three voice profiles: Calls & streaming, Natural voice and Clear voice • Input/output volume, clarity EQ, de-esser, noise gate and automatic volume control • Advanced compressor settings and preset save/import/export • Raw monitor, processed listening, test tone and connection guide • Prefer stability / Prefer low latency modes and diagnostic reports Sound quality and latency depend on your PC, microphone, audio devices and receiving app settings. The noise gate reduces quiet sounds; it does not remove all background noise while you speak. ■ Before you buy Supported: Windows 11 x64 on an Intel/AMD 64-bit PC.
