31 Chapter 5: Editing and repairing audio files The intuitive visual tools in Adobe Soundbooth 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. If you open a mono file, its single channel fills the total height of the Editor panel. Below the panel's default waveform display, which is ideal for evaluating audio amplitude, you can view audio in the spectral display, which reveals audio frequency (low bass to high treble). ❖ To view the spectral display, do any of the following: • In the toolbar, click the Spectral Frequency Display button . • In the Tasks panel, click Remove A Sound. • In the Editor panel, drag the divider between the waveform and spectral displays to gradually change the proportion of each. To instantly show or hide the spectral display, double-click the handle or click the triangle to its right. A B Viewing the waveform and spectral displays A. Drag the divider to change the proportion of each. B. Click the triangle to show or hide the spectral display. See also "Waveform measurements" on page 6 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. Quiet audio has both lower peaks and lower valleys than loud audio. Updated 15 July 2009

Chapter 5: Editing and repairing audio

files

The intuitive visual tools in Adobe Soundbooth 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. If you open a mono file, its single

channel fills the total height of the Editor panel.

Below the panel’s default waveform display, which is ideal for evaluating audio amplitude, you can view audio in the

spectral display, which reveals audio frequency (low bass to high treble).

❖

To view the spectral display, do any of the following:

•

In the toolbar, click the Spectral Frequency Display button

•

In the Tasks panel, click Remove A Sound.

•

In the Editor panel, drag the divider between the waveform and spectral displays to gradually change the proportion

of each. To instantly show or hide the spectral display, double-click the handle or click the triangle to its right.

Viewing the waveform and spectral displays

Drag the divider to change the proportion of each.
