A recording of the royal wedding will be available to download hours after the service comes to an end.
Shortly after Prince William and Kate Middleton say 'I do' on April 29, the entire ceremony will be released digitally through Decca Records to online retailers, including iTunes.
Individual tracks, including the couple's vows, will be also available to download as singles.
On May 5, an official recording of the whole ceremony will also be released on CD, vinyl and cassette.
It will include a booklet containing the order of service, readings, hymns, vows and blessings, as well as the music.
£1 from every album sold will go to charity organisation the Foundation of Prince William and Prince Harry.
