Audio Palette - Audio Customization Technique

      A methodology is described herein that permits a user to
customize computer audio features via a windowed end user interface.

      Customization programs have ignored the audio medium of
computer systems.  There are many such programs that, for example,
change the user's screen colors and character font styles and sizes.
The audio medium should be customizable as well.  This article
describes some of the user benefits of audio customization.

      The mechanism by which a user customizes screen colors is
usually done by permitting the user to select a color (or color
combinations) from a color palette and applying that color to a
portion of the screen (or an object residing on the screen - for
example, text).  This customization technique is easily applicable to
the audio environment.  In lieu of a color palette, the user would
have access to an audio palette.  Each "color" of the palette would
consist of characteristics that chanbe, distinctly, the audio signal
to which it is applied.  Much like a color changes the appearance of
the screen, an audio element of the audio palette changes sound of
the audio signal.  For example, one element of an audio palette may
be called "echo".  When "echo" is applied to an audio signal it
causes the audio signal to be echoed.  These audio elements could
exist in a palette that is easily selectable by the user thru an end
user interface.

      The graphic depicts an example end user interface
implementation to allow users to select audio elements from an audio
palette (Fig. 1).

      The audio elements shown in this palette are a few examples of
the type of audio attributes that can be applied to an audio signal.
The user's audio palette could contain a default set of elements.  It
is also possible to allow the user to provide or create his own auio
elements.

      As previously described, the "echo" audio element, when applied
to an audio signal would cause the audio signal to echo.  The
elements labelled "lo-pass", "hi-pass", and "mid-pass" are low, high
and mid pass filters that allow only the low, high or mid frequencies
of an audio signal to be heard.  All other frequencies are
suppressed.  The audio elements labelled "10hz", "100hz".  "1Khz",
"100Khz".  amd "1Mhz" can be used to boost or soften the audio signal
near these frequency levels (much like an equalizer).  A user would
be allowed to create additional audio elements (of this type) at
other frequencies as well (e.g. have a frequency adjustment mechanism
to create such filters at any desired frequency at the most granular
level allowed by the hardware).  Also included in the palette would
be an "amplitude" audio element to control the loudness of the
signal.  The amplitude element could be modified to soften or
increase the loudness of all frequencies of the input signal.  The
audio signal labelled "notch" is a notch filter that permits a very
s...
