531 sound will be generated instead of the standard beep.
|
|
|
532
|

533 Each element of `sound-alist' is a list describing a sound.
|
|
|
534 The first element of the list is the name of the sound being defined.
|
|
|
535 Subsequent elements of the list are alternating keyword/value pairs:

|
|
536
|
|
|
537 Keyword: Value:
|
|
|
538 ------- -----
|
|
|
539 sound A string of raw sound data, or the name of another sound to
|
|
|
540 play. The symbol `t' here means use the default X beep.
|
|
|
541 volume An integer from 0-100, defaulting to `bell-volume'
|
|
|
542 pitch If using the default X beep, the pitch (Hz) to generate.
|
|
|
543 duration If using the default X beep, the duration (milliseconds).
|
|
|
544
|
|
|
545 For compatibility, elements of `sound-alist' may also be:
|
|
|
546

|
547 ( sound-name . <sound> )
|
|
|
548 ( sound-name <volume> <sound> )

551 load-sound-file.
|
|

552
|
|
|
553 Caveats:
|
|
|
554 - You can only play audio data if running on the console screen of a
|
|
|
555 Sun SparcStation, SGI, or HP9000s700.
|
|
|
556
|
|
|
557 - The pitch, duration, and volume options are available everywhere, but
|
|
|
558 many X servers ignore the `pitch' option.
|
|
|
559
|
|
|
560 The following beep-types are used by emacs itself:
|
|
|
561
|
|
|
562 auto-save-error when an auto-save does not succeed
|
|
|
563 command-error when the emacs command loop catches an error
|
|
|
564 undefined-key when you type a key that is undefined
|
|
|
565 undefined-click when you use an undefined mouse-click combination
|
|
|
566 no-completion during completing-read
|
|
|
567 y-or-n-p when you type something other than 'y' or 'n'
|
|
|
568 yes-or-no-p when you type something other than 'yes' or 'no'
|
|
|
569 default used when nothing else is appropriate.
|
|
|
570
|
|
|
571 Other lisp packages may use other beep types, but these are the ones that
|
|
|
572 the C kernel of Emacs uses.
