efeitos visuais

Visual effects for audio:
Various visual effects are available to be displayed, if desired, during sound reproduction. The choice of the effect type and other characteristics is made in "Settings".


Insert or assign images to audio files:
An image can be assigned to any audio file that will be displayed, if desired, during playback. You have the option of relating the image to the title or album name.
Associating the image with the title, each theme of an album will have its own image; by relating the image to the album name, all themes in that album will display the same image. There is the possibility, in the same album, to particularize a certain theme (or themes) with a different image. After you have assigned an image to the entire album, you can assign a different image to a theme, relating it to the title. The remaining themes will continue to display the image that was related to the album name.
To relate an image to the album name, it is necessary that this information exists in the file's metadata.
For mp3 and wav files, it is also possible to embed the image in the file itself.

Viewing images:
You can move the images and zoom, using the mouse wheel, the key combinations (Ctrl + PagUp), (Ctrl + PageDown) or by holding down the (Z) key while "drawing" a dashed rectangle on the image defining the area you want to expand.

Keyboard shortcuts:
Most keyboard shortcuts are visible on the menus or labels (tooltip) that appear near the buttons. The following shortcuts are not included in this information:
F3 - Opens/Closes the CD/DVD drive drawer.
Right Arrow and Left Arrow - Moves the selected cursor one unit in the direction of the arrow (playback position or sound volume). Together with the Ctrl key it moves 10 units.
Ctrl + 0 (zero) - Centers the current image in the Multi Player window.
Ctrl + 1 - Reduces the Multi Player window to its smallest possible size and centers it on the screen.
F11 or F - switches between normal screen and full screen.
