Creating a New File
Press the New... 
command button on the Home Tab or File Tab (the same New File option can be accessed from the Application Button menu or Quick Access Toolbar). The following window will be opened:
Select the Sample Rate (8'000 - 96'000 Herz), Sample Size (8-bit - 32-bit) and the Number of Channels (1/0 - mono -- 3/4+LFE 7.1 surround). Specify the new file name and check the Auto-add date_time to file name option if necessary. Then click the OK button to quickly create a file of the selected format.
Note:
AVS Audio Editor creates all files using a temporary audio file format and saves all the changes to the edited file only when you select to
Save them using one of the ways.
