Audio file

We recommend using MP3 files to offer audio on your web pages—but you should also use alternative file formats (such as OGG and/or

WAV) so that visitors using Firefox (for Mac or PC) or older PC browsers will be able to use the alternative if the MP3 file format is not

supported. Audio files can be quickly converted using a free online conversion service such as the one at http://audio.online-convert.

com/convert-to-mp3.

Drag and drop the MP3 file onto your Freeway page and then, with the item selected, look at the options in the Item Output Settings

tab of the Inspector.

• Type: If you have your page set to HTML5 or XHTML5, this popup will be

set to Audio by default. If you have the page set to any other HTML level

(HTML 4.01 Transitional, XHTML 1.0 Transitional, etc.) the popup will

display as QuickTime because the page will not validate correctly unless

it has an HTML5 declaration in the head tag, and the audio file will be

output as QuickTime (which may only play on some browsers, especially

PC browsers, if the visitor has the QuickTime plug-in downloaded and

installed).

• Source 2 and Source 3: These popups allow you to offer an alternative

audio file type which a browser can use if the MP3 file format is not

supported. The two main file types you will use in here are OGG or WAV. If

you don’t have those video file types already, you can use OnlineConvert.

com (mentioned above) to convert your MP3 file into one or both of those

file types.

• Preload: This lets the web designer choose a preferred action for how a browser treats the audio file. This set by default to default,

which means that the visitor’s browser preferences will be allowed to control what happens on page load. There are three other

options:

– none: This means that the designer would not like the audio file to load on page load.

– metadata: This means that the designer wants only the metadata of the audio file item to load on page load.

– auto: This means that the designer would like the entire audio file to load on page load (note that this will be chosen if Autoplay

is switched on—see below).

• Controls: This option must be switched on, otherwise the default audio player controller bar will not display.

• Autoplay: With this option switched off, the visitor will need to click on the play button to make the audio file play. With the

option switched on, it will play as soon as it has downloaded.

• Loop: With this option switched off, the audio file will play once and then stop. With the option switched on, the audio will play

over and over.

• Muted: As the name suggests, switching on this option will mute the sound of the audio file, which will mean that the visitor will

need to manually adjust the volume to listen to the file.

The HTML5 audio item is like any other HTML item used on your Freeway page. You can select it and add graphic effects (such as

Shadow or Border) if you wish, etc.

You can see in the above screenshot that the handles of the HTML5 audio item display in red—and this is because it has a Width and

Height of Flexible because that is the default size of a standalone audio controller bar. The height of an audio controller bar will always

be 25px, but you can change the width of the item by clicking on the General Settings tab of the Inspector then changing the Width

to Fixed before entering the value you want to use, or you can scale it by clicking and dragging the center left or center right handles.

QuickTime

QuickTime was once the most common way for Mac users to offer movie content for multimedia and the web. It was also used for

specialist Virtual Reality output or for exporting animations created in 3D modeling programs.

However, although QuickTime works fine on all Mac computers and devices, it is often the case that PC visitors will need to download

and install the QuickTime plug-in to see the multimedia content. Understandably, many PC users are reluctant to download plug-ins

so they can watch a movie or animation due to security concerns (and many office users may not have the authority to do so)—so

QuickTime is now out of favour compared to HTML5 video.

QuickTime movies may consist of both sound and pictures, sound only, or pictures only, and are normally identified by having “.mov”

at the end of the filename.

Drag and drop the MP3 file onto your Freeway page and then,

with the item selected, look at the options in the Item Output

Settings tab of the Inspector.

The “Poster” frame of the movie will then appear inside the item.

The poster frame is the first frame of the movie, or the frame

that’s been set to show as a still image before the movie begins to

play.
