[Tech1] Topic for today Stereo vision

[Alasdair Lawrance]

  A long time ago, John the Noise played me a tape of a particular song, singer and orchestra combination, titles  of all I've unfortunately forgotten.

It started on one channel, then dual mono and finally proper stereo, I know not how, crossed pair live, multi channel or what.

I was mightily impressed, and that started the rot for me, hearing it at proper level on his wonderful KEF Monitors.

I'm sure John will fill in the details, but it did for me!

Don’t blame me, I voted Remain.

He agreed and found that the whole screen acted as a giant speaker. The TV system sensed where a sound source was in the picture and adjusted the apparent position in the stereo feed to suit. No sound bar needed so I retired it. All you sound techies can have a good laugh - I’m only a simple cameraman. However - I like what I am hearing and the clarity is such that I can now listen at a normal volume once again despite my impaired hearing. My wife is very pleased!
