The QuickEnhance Plug-In provides six sequential stages of speech clarification filtering in a single plug-in. It can be operated within many PC-based audio/video editor platforms, including Adobe Audition, Acon Acoustica, iZotope, and Avid Media Composer. With a simple, innovative user interface, QuickEnhance efficiently and effectively improves the intelligibility of voice recordings by reducing typical background noises such as hum, motors and fans, static, and hiss. Additionally, reverberations in speech can be reduced, and multi-band equalization can be applied to improve the final sound quality, with a final AGC stage compensating for near/far talker level differences in the clarified conversation.
