    Chapter 2: Digital audio fundamentals An understanding of key audio concepts helps you get the most out of Adobe Soundbooth CS3. Understanding sound Sound waves Sound starts with vibrations in the air, like those produced by guitar strings, vocal cords, or speaker cones. These vibrations push nearby air molecules together, raising the air pressure slightly.

    Chapter 5: Editing and repairing audio The intuitive visual tools in Adobe Soundbooth CS3 make it easy to edit, optimize, and repair audio. Displaying audio View audio waveforms and spectrums When you open an audio file, the Editor panel provides a visual representation of sound waves. If you open a stereo file, the left channel appears at the top and the right channel appears at the bottom.
  • Page 36 SOUNDBOOTH CS3 User Guide About the waveform display The waveform display shows audio as a series of amplitude peaks and valleys. The x-axis (horizontal ruler) measures time, and the y-axis (vertical ruler) measures amplitude on a decibel scale that ranges from –∞ (negative infinity) for silence to 0 dBFS for loud peaks.

  • Page 53 SOUNDBOOTH CS3 User Guide Compressor The Compressor effect reduces dynamic range, producing consistent volume levels and increasing perceived loudness. Compression is particularly effective for voice-overs, because it helps the speaker stand out over musical soundtracks and background audio. For examples of highly-compressed audio, listen to recordings of modern pop music. By contrast, most jazz recordings are lightly compressed, while typical classical recordings feature no compression at all.
