|

542
|

543 Each element of `sound-alist' is a list describing a sound.
|

544 The first element of the list is the name of the sound being defined.

545 Subsequent elements of the list are alternating keyword/value pairs:

547 Keyword: Value:
|
|
|
548 ------- -----
|
|
|
549 sound A string of raw sound data, or the name of another sound to
|
|
|
550 play. The symbol `t' here means use the default X beep.
|
|
|
551 volume An integer from 0-100, defaulting to `bell-volume'
|
|
|
552 pitch If using the default X beep, the pitch (Hz) to generate.
|
|
|
553 duration If using the default X beep, the duration (milliseconds).
|
|

554
|
|

555 For compatibility, elements of `sound-alist' may also be:
|
|

558 ( sound-name <volume> <sound> )

563 Caveats:
|
|
|
564 - You can only play audio data if running on the console screen of a

|
|
565 Sun SparcStation, SGI, or HP9000s700.
|
|
|
566
|
|
|
567 - The pitch, duration, and volume options are available everywhere, but
|
|
|
568 many X servers ignore the `pitch' option.
|
|
|
569
|
|
|
570 The following beep-types are used by emacs itself:
|
|
|
571
|
|
|
572 auto-save-error when an auto-save does not succeed
|
|
|
573 command-error when the emacs command loop catches an error
|
|
|
574 undefined-key when you type a key that is undefined
|
|
|
575 undefined-click when you use an undefined mouse-click combination
|
|
|
576 no-completion during completing-read
|
|
|
577 y-or-n-p when you type something other than 'y' or 'n'
|
|
|
578 yes-or-no-p when you type something other than 'yes' or 'no'
|
|
|
579 default used when nothing else is appropriate.
|
|
|
580
|
|
|
581 Other lisp packages may use other beep types, but these are the ones that
|
|
|
582 the C kernel of Emacs uses.
