CyberLink Director Suite is a great toolset that includes almost every instrument you may need for editing media files. It's a complete package of audio, image, photo and video editing software.
The suite has common interface design for all programs, and it is rather easy to use despite programs being some of the more advanced tools of the art. There's the AudioDirector for editing, restoring and converting audio files in waveform. This tool has the precision and speed you can only wish for, and its features help you truly customize a track. There's dynamic range correction, equalizer, vocal removal, etc.
Another audio tool is called WaveEditor and is better suited for quick changes and updates of a file in progress. Then there's the PhotoDirector for photo editing by changing tone, contrast, brilliance, lights and shadows. A tool called ColorDirector does the same for video, both as a whole and in specific frames. You can adjust its white balance, contrast, exposure, brightness, darkness, clarity, etc. Both tools support a wide range of formats.
Finally there is PowerDirector, a tool for combining your audio and video files to create a complete product. With a simple drag & drop interface it lets you edit, move and enhance files by adding various effects and cutting, merging, syncing and doing other things to your files. It has built-in Magic Movie Wizard for previewing and producing final video files.
To conclude, CyberLink Director Suite is an all-in-one set of tools that work fast and stable and have so many functions they can serve as professional software. It's a suite well worth the money.
