USING SOUNDBOOTH CS4 33 Editing and repairing audio files View layered or separated waveform channels For stereo and surround-sound files, you can view layered or separated channels. Layered channels overlay each other in different colors, better revealing overall volume changes. By contrast, separated channels appear individually, better revealing distinct volume changes. ❖ Choose View > Channels, and then choose Layered or Separated. A B Channel View options A. Layered B. Separated See also "Change interface brightness and colors" on page 15 Customize the spectral display 1 In the Tasks panel, click Remove A Sound. 2 From the Resolution menu, choose a high setting to display frequencies more accurately, but time location less accurately. Or, choose a low setting to do the opposite. Use high Resolution settings to identify artifacts of long duration (like squeaks or 60-Hz hum). Use low settings to identify transient peaks (like clicks and pops). 3 For Vertical Scale, enter a higher number to display frequencies more logarithmically, or a lower number to display them more linearly. A logarithmic display better reflects the uneven frequency emphasis of human hearing, providing better low-frequency detail. A linear display gives equal weight to each frequency. 4 To limit playback to frequencies you've selected with the Frequency Selection, Rectangular Marquee, or Lasso tools, select Play Selected Frequencies Only. By default, the option above is deselected, so Soundbooth plays all frequencies in the same time range as selected frequencies.
