Puccini - Tosca - Mario Cavaradossi...e lucevan le stelle pitch down by 4%

Same as • Video . However, just to compare or judge the influence of a half tone difference, the pitch is changed.
The pitch of this one is down 4 percent, about a half tone. That would adjust for the easy way that is often taken to play and subsequently record film recordings on European TV (PAL). Pal runs at 25 frames /sec, while the film recorded the scene originally at 24 frames /sec . In that case the film shortens by about 4% and the pitch is raised by about 4 %.
I have listened to much to judge the effects. And the 5 file format conversion I needed, may have affected the quality.
