Operates entirely by a graphical user interface , although there are key shortcuts for the most-used operations. Reference calls can be appended to a sequence view and are automatically adjusted to match the time and frequency scale of the view. Any call may be selected for very high resolution standard view display and have a reference call displayed beside it with matching time and frequency scales.
Customized versions are available for other time expansion factors.
Calls are processed from standard wav files. The software automatically recognizes and displays which format. Calls may be recorded in any of these wav formats with the Recorder Accessory , which provides real time amplitude feedback during recording. The Recorder Accessory allows the selection of desired segment before saving to file. This is especially useful for selecting a continuous sequence from a looping audio output.
