|
|
690 volume An integer from 0-100, defaulting to `bell-volume'
|
|
|
691 pitch If using the default X beep, the pitch (Hz) to generate.
|
|
|
692 duration If using the default X beep, the duration (milliseconds).

694 For compatibility, elements of `sound-alist' may also be:
|
|
|
695
|
|
|
696 ( sound-name . <sound> )
|
|
|
697 ( sound-name <volume> <sound> )
|
|
|
698

|
699 You should probably add things to this list by calling the function
|
|
|
700 load-sound-file.

|
702 Caveats:
|
|
|
703 - XEmacs must be built with sound support for your system. Not all
|
|
|
704 systems support sound.
|
|
|
705
|
|
|
706 - The pitch, duration, and volume options are available everywhere, but
|
|
|
707 many X servers ignore the `pitch' option.
|
|
|
708
|
|
793
|
709 Sound symbols that map directly to data should be considered named sounds;
|
|
|
710 sound symbols that map to other sounds should be considered abstract
|
|
|
711 sounds, and are used when a particular behavior or state occurs. See
|
|
|
712 `ding' for a list of the standard abstract sounds.
