A fifteen (15) minute sampler of Bernard Herrmann's score to Alfred Hitchcock's 1959 film,
North By Northwest
The original soundtrack was recorded in stereo and has wide dynamic range
I believe some music services are streaming a file of the original soundtrack with 24-bit resolution
But as the producer stated in the liner notes, one master tape was very much detoriated, unfortunately the "famous" cues like the beginning and the chase at Mount Rushmore were affected. This can be also heard in the video, the tracks affected sound much more muffled.
But the dawn of the digital era, labels like Unicorn - Kanchana released new recordings of Movie soundtracks,
using just stereo microphones hooked to a PCM recorder like Soundstram or Sony:

P.S. I always loved Jerry Goldsmiths "Star Trek - The Motion Picture" from 1979. The sessions were recorded simultaneously with a Sony PCM hooked to a stereo mic
plus the "classical" setup / way, using multiple mics for closer recording of the orchestras' sections, recording this on multitrack tape - I assume this was to save time, so that the PCM-based soundtrack could be prepared independently of the movies' mixing.
La-LaLand records released the complete score in 2012, using the multitrack source - sounds much better!
