Just came across this post from Open Culture on the first computer generated music.
It appears that although Turing had worked out that his computer could be made to produce music but wasn’t interested in pursuing this. Christoper Strachey played with the concept and came up with some recognisable tunes. The Open Culture blog has a wonderful piece on it.
Apparently the BBC recorded it but the disc is not accurate. The British Library Sound and Vision blog has a piece on it by Jack Copeland and Jason Long discussing the finding of the disc and the work that was needed to record the original tune.
This is not part of the research that I am interested in but has relevancy in the recovering of the audio and its imprecision.
