Creating midlets with sound

CellPix can generate midlets with a sound track for on any standard MIDP 2.0 phone (or a Midp 1.0 phone that supports the Java JSR 135 API). To do this press the Midp 2.0 button.

Adding sound files

A list of one or many sound files can be added to a midlet and the these files may be a mixture of midi, mp3, wav, au or amr files. The same file can be repeated in the list but this won't make the midlet size larger. If a silent file is needed in the list then an Midi file that doesn't play anything can be added to act as padding.

Sound playing

Sound files will be played continuously while the slide show is in progress but will stop if the slideshow is stopped by some action such as going to the index. if more than one sound file is set then the next sound file in the list will play when the next image appears. The CellPix midlet checks if a sound file's format is playable and if not then it is skipped.

Volume control

Sound volume is controlled by using the UP and DOWN arrow keys (or corresponding joystick actions). This sound dialog includes an option to change volume control to be the '6' and '8' keys, in which case the up/down button will duplicate the functions of the right/left button. The '5' key always acts as a toggle to turn sound on and off.

Checking supported sound formats

Not all phones support all formats. Pressing the '#' key while a CellPix midlet is active will show a list of supported formats.
