Select frequency ranges

In the spectral display, three tools let you select audio data within specific frequencies. The Frequency Selection tool selects an entire frequency range throughout a file, the Marquee tool selects a rectangular area, and the Lasso tool creates free‑form selections. All three tools provide powerful flexibility for audio restoration projects. For example, if you find a sonic imperfection, you can select and edit just the affected frequencies, with superior results and faster processing.

  1. In the toolbar, click the Spectral Frequency Display button . Then select the Frequency Selection , Marquee , or Lasso  tool.
  2. In the spectral display of the Editor panel, drag to select audio.

    • To extend or shorten a selection, drag its left or right edge in the timeline ruler.

    • To move the selection without changing its length, drag the middle of the selection in the timeline ruler.
