Since its launch in March, Audioboo, the service which allows users to record and upload short audio recordings, has notched up 30,000 registered users and been taken up by both hyperlocal and international news media.

This Saturday ITV.com is planning to use the tool as part of its FA Cup Final coverage: fans using the Audioboo iPhone app will be able to submit their audio reactions to the site.

Significantly this seems to be the first foray into running a paid-for version of an Audioboo account.

As CEO Mark Rock explains in this blog post, there will always be a free version of the tool, but the firm is developing a range of paid-for options intended for media organisations.

Audioboo Pro will be the version used by ITV tomorrow, ‘which will contain a series of web tools which make it easy for companies, particularly media companies, to manage content coming from their audiences’.

Key to these tools are ‘magic tags’ – a private tag that the account use can apply to any Audioboo content creating a specific feed for use in a player on their site. ITV are using this system to help moderate the ‘boos’ left by fans.

The use of Audioboo by ITV marks a focus by the broadcaster on capturing the online buzz about the match alongside the roar of the crowd within Wembley Stadium. As such, the site will use Twitter aggregator Twitterfall to stream relevant updates to the microblogging site.

In addition, using a tool developed by thruSITES:

“The players’ names and faces will appear alongside bars which will move up and down to reflect the buzz around players during the game. The tool will be available after the match so that fans can scrub along a timeline to see which players caused a buzz at crucial moments.”
