´óÏó´«Ã½

Nice work, very interesting. Love the comment.

Doesn't Andrew McParland look like Daily Mirror hack Kevin Maguire?

Any chance this interesting clip can also be made available as a download in "no availability" areas such as mine (Italy?)

Thanks, Andy

A touch of deja vu all over again. I used to be a DJ on the ´óÏó´«Ã½ and in the days of vinyl you could judge what happened during a disc by looking at the patterns on the surface. The patterns varied depending on the tonal make-up of the sound such that high frequency rhythmic sounds (such as a hi-hat or cymbal) would show as a lighter pattern, often spiralling across the surface (especially on reggae discs I remember). Since bass notes had larger excursions of the groove they were also apparent due to larger areas of 'blank' plastic.

I recall seeing a guy on a TV program years ago whose party piece was recognising a classical symphony just by looking at the disc. I didn't get that far (other than some Mahler with strong tympani) but I used to skip across the surface of an album, checking out each of the sections that showed changes in the music, before coming back and re-listening to anything that had grabbed my attention.

I have often wondered whether a similar technique could be applied to a digital recording as an aid to analysis and now I've seen it.
