USING ADOBE AUDITION 37 Editing audio files More Help topics "Select spectral ranges" on page 39 "Customize the spectral display" on page 37 "Techniques for restoring audio" on page 86 View layered or uniquely colored waveform channels For stereo and 5.1 surround files, you can view layered or uniquely colored channels. Layered channels better reveal overall volume changes. Uniquely colored channels help you visually distinguish them. ❖ Choose View > Waveform Channels, and then select Layered or Uniquely Colored. A B Channel View options A. Uniquely Colored B. Layered (with Uniquely Colored still selected) More Help topics "Change interface colors, brightness, and performance" on page 17 Customize the spectral display The Spectral Display preferences help you enhance different details and better isolate artifacts. 1 Choose Edit > Preferences > Spectral Display (Windows) or Audition > Preferences > Spectral Display (Mac OS). 2 Set the following options Windowing Function Determines the Fast Fourier transform shape. These functions are listed in order from narrowest to widest. Narrower functions include fewer surrounding frequencies but less precisely reflect center frequencies. Wider functions include more surrounding frequencies but more precisely reflect center frequencies. The Hamming and Blackman options provide excellent overall results. Spectral Resolution Specifies the number of vertical bands used to draw frequencies. As you increase resolution, frequency accuracy increases, but time accuracy decreases. Experiment to find the right balance for your audio content. Highly percussive audio, for example, may be better reflected by low resolution. To adjust resolution directly in the Editor panel, right-click the vertical ruler next to the spectral display, and choose Increase or Decrease Spectral Resolution. Decibel Range Changes the amplitude range over which frequencies are displayed. Increasing the range intensifies colors, helping you see more detail in quieter audio. This value simply adjusts the spectral display; it does not change audio amplitude. Play Only Selected Frequencies When A Spectral Selection Exists Deselect this option to hear all frequencies in the same time range as a selection. Last updated 2/16/2012
