[sdiy] Frequency shifted from BBD?

[brianw]

That particular article seems to have a few issues.

For one thing, an engineer that worked with The Beach Boys in the studio and on tour says that the Eltro was not used for those songs, and was not even available at the time.

For another thing, I don't hear warbling in the computer speech in 2001: A Space Odyssey, and I really do not understand why advanced, real-time pitch shifting would be needed in a movie production. Surely, none of the audio, sound effects, or dialog were recorded in real time during the performance. The principle of simplicity says that the computer speech would have been recorded to tape and simply slowed down on playback when mixing the movie sound. If the tempo needed to be maintained, the voice actor simply could have talked slightly faster in the section where the pitch needed to be dropped. Yes, the sound is strange at the end, but the human voice would not sound natural at such low speed or pitch anyway. I'm not hearing what's mentioned in the article, despite the story recounted from Carlos recounted from Kubrick.

(see https://valhalladsp.com/2010/05/04/pitch-shifters-pre-digital/) I remember a photo from the WDR Electronic Music Studio, where Karl Heinz Stockhausen used one, which had 12(?) playback heads on a rotating plate. But I don't find the picture at the moment.
