As the leading players in the radio industry gather today in Salford , much of the conversation will be about the topic of innovation. Listeners are currently very satisfied with radio services but digital technology does bring opportunities to keep improving what we offer. This summer, 主播大秀 Radio 3 completed. A positive listener response led us to look at a permanent launch. Therefore, from the beginning of December, we will offer "HD Sound" (as we are calling it) on Radio 3 and listen online. We will quickly assess the performance of this before making the higher quality stream available on iPlayer and the proposed radio industry player (called Radioplayer). Radio 3 listeners will get the benefit of the highest quality broadcast available anywhere. Interestingly, it was Radio 3 that led the charge in 1971 as radio moved to stereo, and once again it is excellent to see it at the forefront of innovation.

As with Stereo, I would expect to see further roll-outs of HD Sound over time and we have already announced that we will be trialling it for . I am expecting that the performances by Elton John,Robert Plant and Neil Diamond will all be available.

A few days ago I hosted a celebration of the launch of our new radio Outside Broadcast (OB) fleet. The fleet comprises of state of the art sound trucks that you may see parked up at countless festivals, concerts and events throughout the year. The new trucks have come to the rescue of our ageing vehicles which have been heavily used for many years. Capital investment is very significant (and rare) for 主播大秀 radio, so it represents a landmark moment.

Of course, inside the trucks are some of the most accomplished audio engineers, technicians and producers in the world. When you meet these teams, who have decades of experience, you are struck by their passion for delivering a perfect broadcast and the enormous pride that they have in representing the 主播大秀 across the country. Everything that you hear from live events beyond the studio is utterly dependent on their expertise.

This year, during some of my most enjoyable days, I visited our trucks across many locations such as outside the , at or Maida Vale. However, perhaps I appreciate what these trucks deliver most in a cottage in Cornwall every summer, listening to live coverage of the Proms. The quality of our OB Fleet combined with the skill of the team comfortably closes the distance between the Albert Hall and the Lizard.

Furthermore, the OB team are a group that are constantly pushing the boundaries of technology. Immediately after last week's launch, they were testing new ways of producing music during . I will be returning to this theme of audio innovation as we bring news of further developments to improve the quality of our broadcasting.

Meanwhile, if you do have ideas on how radio should innovate, don't hesitate to leave a comment here on the blog.
