Sound file editing

The sound file editing functions include:
Cut, Copy, Paste, Insert silence, Reverse, Adjust volume, Filter and Undo edit.

Using these, it is possible to enhance the sound file in many ways, e.g. to remove undesired portions of a signal or to create a new sound file by cutting and pasting sound clips from other files.

The filter function enables frequency-selective editing of the sound file. Removing e.g. low-frequency noise from a selected portion of the sound file is an easy matter. The filter characteristics are chosen in the "Filter design dialog box", where it is also possible to study the frequency response of the designed filter before actually filtering the sound file.
