The sample display is where you can edit MP3 and the supported audio files graphically with the mouse on a 3D sample display. MPEG files are edited without decoding, this means there is no degradation of quality and it's also very fast, as there is no need to decode and re-encode the files.

Selection start position can be set with left mouse button click, end position with right mouse button click. Point to a position and roll the mousewheel up to zoom in and down to zoom out. You can play the stream from the position where you click with the middle mouse button.

Commands (above sample display)

This will pop-up a dialog with options to set artist, title, etc. for the new subsong. Use the menu: File/Save Subsong Layout to save the subsong layout or menu: File/Generate .CUE Sheet. Subsongs are stored in ID3v2 tag, so only audio file formats support subsongs which can have ID3v2 tags like MP3, MP2, Flac, WAV, .CUE file is generated aside the audio file with the same name but with .CUE extension. An exising subsong can be moved with left mouse clicking on a subsong and dragging it with the mouse. Right mouse button clicking on a subsongs deletes it.
