You don't. &nbsp;There is no editing in HTML Audio.

<div>
create the individual tracks on your mac, then upload them to html page

Tom's suggestion of Audacity is good.<br />
<br />
Audacity is very memory efficient + fast to slice + export parts of an mp3 as other mp3s.

Thanks to everyone who replied. I always appreciate smart people that have done something correctly before I take it on. :-)<br />
<br />
While it was a little time-consuming, I believe that this is going to do the trick:<br />

I stuck with Audacity (mostly because I had it downloaded already and the libraries installed that I wanted). It was easier than doing it in ProTools and once the entire concert is broken up, I just use the standard HTML audio tags to set it up.<br />
<br />
Thanks again.

I have a single concert MP3. I'd like to break up this MP3 so that folks can click on a link and go to a particular song. <br />
<br />
I've used programs like Sublr (for Mac) to break up MP4 files, but <i>how the heck do I do it in HTML using just the native Audio in HTML5</i>?<br />
<br />
Thanks!

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.

HTML

Multimedia applications are those programs that integrate more than one media at a time; browsers are the most obvious. However, the term has come to include the use of programs that enable the use of any component that isn’t simple text and static graphics, such as audio, video, animation, virtual reality, conferencing and monitoring.
