Without
wasting much of time, we can cut the introduction of HTML 5 in short,
it is the future of the internet world. Let’s suck it up and get on some
facts. If you are not using HTML5 then there could be reasons like, it
is not completely adopted by people yet, you love writing the HTML5
codes, your IE doesn’t support HTML5 or it could be any other such
probable reason. Whatever the reason is, whether you like this format or
not, the truth that you need to gulp is, HTML5 is the latest version of
HTML that will soon dominate the whole intenet world.
HTML
5 caters some superior and top-notch multimedia options within a web
page like Graphics and Audio processing, that would surely get web
developers hands on it, which HTML4 was unable to do, moreover working
on such amazing stuff was impossible to imagine with HTML4. Hence, to
make you experience the amazing functionality of HTML5, we have
three-stage staircase, which on climbing, will lead you to know – how to
create Audio visualisation within a HTML5 web page.
 First Stage of Staircase: To Create Audio Visualisation
Creativity
and uniqueness always attract the eye and sometimes serve as the key to
success as well. Keeping that in mind, first thing that we need to
carry out is develop an idea. An idea should be developed so creatively
and uniquely that it suits best with the audio file. For those who are
not aware of the details of HTML5, let us tell you that a new tag has
been added to HTML5 with the help of which we can facilely manipulate
any audio file incorporated in the webpage.
You
must be wondering what does this new tag offer? This tag supplies a
media player for audio file that delivers a media player structure with
time, volume control and other exciting features. But we are focusing
over the visualisation part and these features are not enough to create
visualisation. Audio visualisation is not a child’s play, it requires
synchronisation with an audio file. This process of audio visualisation
involves the extraction of the audio data from the audio file which can
be extracted from a file using the pre-processor that can efficiently be
used later for the coding purpose.
Second Stage of Staircase: To Build Visual Graphics
This
stage demands concentration. Before we start with the infixing of the
visualisation with an audio file, we need to sketch out the graphical
resources that are essential and would be required for the
visualisation. In this stage the designing part comes into play mainly.
Those who are planning to create lyrics based visualisation, need to
focus on the design of the backdrop (where the lyrics will appear) of
the page. To carry out the lyrics visualisation, you will have to create
the timeline record of the lyrics. Here, synchronisation should be
given a bit of attention, because if the timeline of the lyrics is not
perfectly synchronised with the audio stream, it would create an
embarrassing visualisation. Hence, synchronisation is not what you can
sneeze at, it is the core element to escape the embarrassment.
If
carrying out such task is difficult for you, you need not worry! You
can go for wave based visualisation that would exhibit wave peaks with
high volume; it is simpler and easier to develop as it requires minimal
graphic resources. Although we can use sample colors or textures to
create waves, but for such visualisations nothing can be done without an
audio data. It acts as an essential element to create wave based
visualisation.
