VFEdit Professional Prompt Editor Sound your best! Let VFEdit(r) turn your multimedia or voice processing PC into a voice prompt recording studio. VFEdit edits sound the way a word processor edits text - with VFEdit you can see and hear the waveform while you work. VFEdit is the only native mode, direct-to-disk, integrated audio editor for the Microsoft Windows(r) environment. Native mode means you can edit compressed PCM instantly without losing fidelity with conversions. Direct-to-disk capability lets you edit files of any size. Integrated editing lets work on files in one format - while playing and recording them in another. Why? So you can create perfect voice prompts for your applications.
