Book excerpt: A project-based book that deals with Adobe Audition (formerly Cool Edit Pro), included in the Adobe Video Collection, this guide explores creating soundtracks for digital video and demonstrates how to use the software to start recording, editing, and producing immediately. Examined are how to edit, mix, and add built-in effects to AVI soundtracks while watching movie playback, how to clean up poor quality audio with powerful noise reduction tools, and how to use sound effects such as sweetening and mixing. Recording engineers will learn how to customize Audition, record multitrack sessions, transform the multitrack mix into a stereo or surround-sound experience, edit audio files using sample-accurate tools, and mix up to 128 tracks of audio. Working with powerful DSP and analysis tools including DirectX effects is covered, as is importing audio (WAV) files from Adobe Audition into projects created with Adobe Premiere Pro or Adobe After Effects.
