Audio signatures for BBC radio networks

Written in


Interesting stuff from our R&D team – aka Tristan Ferne – automatically produced radio signatures for BBC radio networks, using the iTunes signature maker.

“I have a directory for each radio station on a particular day with an MP3 file for each programme and I run the application over this. Each random chunk is then cross-faded into the next one in the same order as the programmes were broadcast. This gives a 1-minute signature file per day per radio station, hopefully representing what went on that day…”

Laden with issues, editorial and technical, which Tristan explores further in his blog post. We’re not quite sure how, or indeed if, to deploy them yet – though we do have a set of potential locations and functions in mind. Interesting either way.
