This command loads one or more files in Vox Studio. It opens a dialog box from which you can browse to and select the files you want to load.
By default Vox Studio looks for files in the directories defined in the Tools/Defaults/Folder defaults menu. Vox Studio also looks by default for ".wav" files or telephony files as defined in the same default menu. You can change these defaults at any time, or you can change the proposed default on-the-fly while using Vox Studio. This behavior is intended to simplify the work of those who have to manipulate thousands of files all located in the same folder and all of the same type. If you just want to edit a single file this behavior may not be that helpful.
If the file you open is a file type which has a recognizable header ( ".wav" and ".vsn" files have such headers for instance ) then Vox Studio gets all the file information it needs from the header portion of the file and will not bother you with additional questions.
Vox Studio, however, cannot guess what kind of sound data you have in your files unless it is explicitly written in the file or unless you tell Vox Studio what it is. Therefore, if the file you open is a headerless file (Dialogic ".vox" for instance) or a file with a non-recognizable header, then, when needed, Vox Studio will open a dialog box and request additional information about the file such as sample rate and coding format.
Telephony format files often lack a header (luckily there are a few exceptions) and the program user is the only one able to provide the information that Vox Studio needs to read the file data correctly. It is, of course, crucial to give Vox Studio the right file information! If you do not, Vox Studio will still read the file but what you will hear or see will be junk. Typically, if you hear screeching noise instead of normal sounds, then you have probably selected the wrong coding algorithm (ADPCM instead of A-law for example). If your file plays too fast or too slow, then you have given the wrong sample rate to Vox Studio.
