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.
